    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934
(``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that
on April 21, 2022, MEMX LLC (``MEMX'' or the ``Exchange'') filed with
the Securities and Exchange Commission (``SEC'' or ``Commission'') the
proposed rule change as described in Items I and II below, which Items
have been prepared by the Exchange. The Commission is publishing this
notice to solicit comments on the proposed rule change from interested
persons.

    \2\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

I. Self-Regulatory Organization's Statement of the Terms of Substance
of the Proposed Rule Change

    The Exchange is filing with the Commission a proposed rule change
to adopt rules to govern the trading of options on the Exchange. The
text of the proposed rule change is provided in Exhibit 5.

II. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements
concerning the purpose of and basis for the proposed rule change and
discussed any comments it received on the proposed rule change. The
text of these statements may be examined at the places specified in
Item IV below. The Exchange has prepared summaries, set forth in
sections A, B, and C below, of the most significant aspects of such
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change

Purpose
    The Exchange is proposing to adopt a series of rules in connection
with MEMX Options, which will be a facility of the Exchange. MEMX
Options will operate an electronic trading system developed to trade
options (the ``System'') leveraging the Exchange's existing robust and
resilient technology platform that it uses to operate its cash equities
market today. The fundamental premise of the proposal is that the
Exchange will operate its options market much as it operates its cash
equities market today and in a manner similar to that of other options
exchanges, with a simplified suite of conventional order types and
functionality that is designed to provide for an efficient, robust, and
transparent order matching process. Much of the proposed functionality
for MEMX Options is substantially similar to that offered by other
options exchanges, primarily Cboe BZX Exchange, Inc. (``BZX''). Thus,
the Exchange proposes to adopt rules applicable to MEMX Options that
are substantively identical or substantially similar to the approved
rules of BZX applicable to the BZX options market (``BZX Options''),
with certain proposed changes or omissions that are described below.
    The System will provide for the electronic display and execution of
orders in price/time priority without regard to the status of the
entities that are entering orders. All Exchange Members will be
eligible to participate in MEMX Options provided that the Exchange
specifically authorizes them to trade in the System. The System will

provide a routing service for orders when trading interest is not
present on MEMX Options and will comply with all applicable securities
laws and regulations and the obligations of the Options Order
Protection and Locked/Crossed Market Plan.
MEMX Options Members
    Pursuant to the proposed rules in Chapter 17 (Participation on MEMX
Options), the Exchange will authorize any Exchange Member who meets
certain enumerated qualification requirements (any such Member, an
``Options Member'') and any Options Member's Sponsored Participants to
obtain access to, and transact business on, MEMX Options.
    There will be two types of Options Members--Options Order Entry
Firms (``OEFs'') and Options Market Makers. OEFs will be those Options
Members representing Customer Orders as agent on MEMX Options or
trading as principal on MEMX Options. Options Market Makers will be
those Options Members registered with the Exchange as Options Market
Makers pursuant to proposed Rule 22.2. To become an Options Market
Maker, an Options Member will be required to register by filing a
written application. The Exchange will not place any limit on the
number of entities that may become Options Market Makers, the number of
appointments an Options Market Maker may have, or the number of Options
Market Makers that may have appointments in a class unless the Exchange
determines to impose any such limit based on system constraints,
capacity restrictions, or other factors relevant to protecting the
integrity of the System. The Exchange will not impose any such
limitations until it has submitted objective standards for imposing the
limits to the Commission for its review and approval.
    Options Market Makers will be required to electronically engage in
a course of dealing reasonably calculated to contribute to the
maintenance of fair and orderly markets. Among other things, an Options
Market Maker would generally have to satisfy the following
responsibilities and duties during trading: (1) On a daily basis
maintain a two-sided market on a continuous basis in at least 60% of
the cumulative number of seconds, or such higher percentage as the
Exchange may announce in advance, for which that Options Market Maker's
appointed classes are open for trading, excluding any adjusted series,
any intraday add-on series on the day during which such series are
added for trading, any Quarterly Option Series, and any series with an
expiration of greater than 270 days; \3\ (2) enter a size of at least
one contract for its best bid and its best offer; and (3) maintain
minimum net capital in accordance with Commission and Exchange rules.
Substantial or continued failure by an Options Market Maker to meet any
of its obligations and duties will subject the Options Market Maker to
disciplinary action, suspension, or revocation of the Options Market
Maker's registration as such or its appointment in one or more of its
appointed options classes.
---------------------------------------------------------------------------

    \3\ The Exchange notes that it also proposes to adopt provisions
that exclude from the calculation of continuous quoting those times
that an Options Market Maker is experiencing a technical failure or
limitation, during a trading halt, suspension or pause in the
underlying security, or when the underlying security is in a limit
up-limit down state.
---------------------------------------------------------------------------

    Options Market Makers receive certain benefits for carrying out
their duties. For example, a lender may extend credit to a broker-
dealer without regard to the restrictions in Regulation T of the Board
of Governors of the Federal Reserve System if the credit is to be used
to finance the broker-dealer's activities as a specialist or market
maker on a national securities exchange. Thus, an Options Market Maker
has a corresponding obligation to hold itself out as willing to buy and
sell options for its own account on a regular or continuous basis to
justify this favorable treatment.
    Every Options Member shall at all times maintain membership in
another registered options exchange that is not registered solely under
Section 6(g) of the Exchange Act \4\ or in FINRA. OEF's that transact
business with Public Customers must at all times be members of FINRA.
Pursuant to proposed Rule 17.2(g), every Options Member will be
required to have at least one registered Options Principal who
satisfies the criteria of that rule, including the satisfaction of a
proper qualification examination. An OEF may only transact business
with Public Customers if such Options Member also is an Options Member
of another registered national securities exchange or association with
which the Exchange has entered into an agreement under Rule 17d-2 under
the Exchange Act \5\ pursuant to which such other exchange or
association shall be the designated options examining authority for the
OEF.
---------------------------------------------------------------------------

    \4\ 15 U.S.C. 78f(g).
    \5\ 17 CFR 240.17d-2.
---------------------------------------------------------------------------

    The proposed rules relating to qualification and participation on
MEMX Options as an Options Member (including as an OEF and an Options
Market Maker) are substantively identical to the relevant rules of BZX
Options.\6\
---------------------------------------------------------------------------

    \6\ See BZX Rules, Chapters XVII and XXII.
---------------------------------------------------------------------------

    As provided in proposed Rule 16.2, existing Exchange Rules
applicable to the MEMX equities market contained in Chapters 1 through
15 of the Exchange Rules will apply to Options Members unless a
specific Exchange Rule applicable to the MEMX Options market (proposed
Chapters 16 through 29 of the Exchange Rules) governs or unless the
context otherwise requires. Options Members can therefore provide
sponsored access to the MEMX Options Exchange to a non-Member (i.e., a
Sponsored Participant) pursuant to Rule 11.3 of the Exchange Rules.

Rule 16.1 (Definitions), which are to be used in proposed Chapters 16

Execution System
    The Exchange's options System will leverage the Exchange's current
state-of-the-art technology, including its customer connectivity,
messaging protocols, quotation and execution engine, order router, data
feeds, and network infrastructure. This approach minimizes the
technical effort required for existing Exchange Members to begin
trading options on MEMX Options. As a result, MEMX Options will closely
resemble the Exchange's equities market, as well as other options
markets, such as BZX Options, that offer true price/time priority
across all participants rather than differentiating between
participant/trading interest.
    Like the Exchange's system for equities, as well as the BZX Options
market, all trading interest entered into the System will be
automatically executable. Orders entered into the System will be
displayed anonymously. Thus, the System will offer anonymous

trading, however, options trades are not currently anonymous through
settlement. Accordingly, as set forth in proposed Rule 21.10,
aggregated and individual transaction reports produced by the System
will indicate the details of a User's transactions, including the
contra party's executing firm ID (``EFID''), capacity, and clearing
firm account number.\8\ The Exchange will become an exchange member of
the Options Clearing Corporation (``OCC''). The System will be linked
to OCC for the Exchange to transmit locked-in trades for clearance and
settlement.
---------------------------------------------------------------------------

    \8\ The Exchange shall also reveal a User's identity: (i) When a
registered clearing agency ceases to act for a participant, or the
User's clearing firm, and the registered clearing agency determines
not to guarantee the settlement of the User's trades; and (ii) for
regulatory purposes or to comply with an order of an arbitrator or
court. See proposed Rule 21.10. The Exchange notes that proposed
Rule 21.10 is identical to BZX Rule 21.10.
---------------------------------------------------------------------------

    Hours of Operation. As stated in proposed Rule 21.2, the MEMX
Options System will begin accepting orders after 9:30 a.m. Eastern Time
pursuant to the market opening procedures described in proposed Rule
21.7. Orders and bids and offers shall be open and available until 4:00
p.m. Eastern Time except for option contracts on Fund Shares, as
defined in proposed Rule 19.3(i), option contracts on exchange-traded
notes including Index-Linked Securities, as defined in proposed Rule
19.3(l), and option contracts on broad-based indexes, as defined in
proposed Rule 29.1(j), which may close as of 4:15 p.m. Eastern Time.
The proposed hours of operation on MEMX Options are the same as on BZX
Options, except that BZX Options begins accepting orders at 7:30 a.m.
Eastern Time that are then processed in the BZX Options opening process
beginning at 9:30 a.m. Eastern Time.
    Units of Trading. As stated in proposed Rule 21.3, the unit of
trading in each series of options traded on MEMX Options will be the
unit of trading established for that series by the OCC pursuant to the
rules of the OCC and the agreements of the Exchange with the OCC. The
proposed determination of the unit of trading for a series of options
traded on MEMX Options is the same as on BZX Options pursuant to BZX
Rule 21.3.
    Minimum Quotation and Trading Increments. As stated in proposed
Rule 21.5(a), the Exchange is proposing to apply the following
quotation increments: (1) If the options series is trading at less than
$3.00, five (5) cents; (2) if the options series is trading at $3.00 or
higher, ten (10) cents; and (3) if the options series is trading
pursuant to the Penny Interval Program one (1) cent if the options
series is trading at less than $3.00, five (5) cents if the options
series is trading at $3.00 or higher, unless for QQQQ, SPY, or IWM
where the minimum quoting increment will be one (1) cent for all
series. In addition, as stated in proposed Rule 21.5(b), the Exchange
is proposing that the minimum trading increment for options contracts
traded on MEMX Options will be one (1) cent for all series. Such
proposed minimum quotation and trading increments are the same as on
BZX Options pursuant to BZX Rules 21.5(a) and (b).
    Penny Interval Program. As set forth in proposed Rule 21.5(d), the
Exchange is proposing to adopt a Penny Interval Program that is
substantially similar to the penny programs of other exchanges,
including BZX Options pursuant to BZX Rule 21.5(d), which includes
minimum quoting requirements for option classes listed under the Penny
Interval Program. However, eligibility for inclusion in the Penny
Interval Program will be limited to those classes already operating
under penny programs of other options exchanges at the time MEMX
Options is launched. The list of option classes included in the Penny
Interval Program will be announced by the Exchange via circular
distributed to Options Members and published by the Exchange on its
website.
    Order Types and Handling Instructions. The System will make
available to Users two Order Types (as defined in proposed Rule
21.1(d))--Limit Orders and Market Orders--as well as various other
instructions and modifiers that can be appended to such orders. The
characteristics and functionality of each Order Type is substantially
similar to what is currently approved for use in the Exchange's
equities trading facility or on other options exchanges, including BZX
Options, except where described below. MEMX Options will support bulk
messages for Options Market Makers as specified in the description of
each Order Type or other instruction. Proposed Rule 21.1(d) includes
the following details with respect to Limit Orders and Market Orders:
     Limit Order. Limit Orders are orders (including bulk
messages) to buy or sell an option at a specified price or better. A
Limit Order is marketable when, for a Limit Order to buy, at the time
it is entered into the System, the order is priced at the current
inside offer or higher, or for a Limit Order to sell, at the time it is
entered into the System, the order is priced at the current inside bid
or lower.
     Market Order. Market Orders are orders to buy or sell at
the best price available at the time of execution. Market Orders to buy
or sell an option traded on MEMX Options will be rejected if they are
received when the underlying security is subject to a ``Limit State''
or ``Straddle State'' as defined in the Plan to Address Extraordinary
Market Volatility Pursuant to Rule 608 of Regulation NMS under the Act
(the ``Limit Up-Limit Down Plan''). Bulk messages may not be Market
Orders.
    The System will also make available to Users several additional
instructions that can be designated on an order (``Handling
Instructions''). A Handling Instruction applied to a bulk message
applies to each bid and offer within that bulk message. The Handling
Instructions available on MEMX Options are described in proposed Rule
21.1(e) and will include the following:
     Book Only. Book Only is an instruction that an order is to
be ranked and executed on the Exchange pursuant to proposed Rule 21.8
(Order Display and Book Processing) or cancelled, as appropriate,
without routing away to another options exchange. Users may designate
bulk messages as Book Only as set forth in proposed Rule 21.1(l).
     Post Only. Post Only is an instruction that an order is to
be ranked and executed on the Exchange pursuant to proposed Rule 21.8
(Order Display and Book Processing) or cancelled, as appropriate,
without routing away to another options exchange except that the order
will not remove liquidity from the MEMX Options Book. The Exchange
notes that, unlike a Post Only Order on BZX Options, an order with a
Post Only instruction on MEMX Options will not remove liquidity even if
the value of price improvement associated with such execution equals or
exceeds the sum of fees charged for such execution and the value of any
rebate that would be provided if the order posted to the MEMX Options
Book and subsequently provided liquidity.\9\ A Market Order cannot be
designated as Post Only.\10\ Users may designate bulk messages as

Post Only as set forth in proposed Rule 21.1(l).
---------------------------------------------------------------------------

    \9\ The Exchange notes that other options exchanges offer
functionality equivalent to the Post Only instruction that does not
remove liquidity based on potential price improvement. See, e.g.,
NYSE Arca Rule 6.62-O.(t) and NYSE Arca Rule 6.62P-O(e)(2), each of
which defines an ALO Order, which is an order that does not remove
liquidity from the NYSE Arca order book without any exception for
removing liquidity when price improvement could be obtained.
    \10\ The Exchange notes that the comparable description of Post
Only Orders on BZX Options in BZX Rule 21.1(d)(8) does not specify
that Market Orders cannot be designated as Post Only, however, the
Exchange believes the proposed functionality is the same.
---------------------------------------------------------------------------

     Intermarket Sweep Order (``ISO''). ISOs are orders that
shall have the meaning provided in proposed Rule 27.1, which relates to
intermarket trading. Such orders may be executed at one or multiple
price levels in the System without regard to Protected Quotations at
other options exchanges (i.e., may trade through such quotations). The
Exchange relies on the marking of an order as an ISO order when
handling such order, and thus, it is the entering Options Member's
responsibility, not the Exchange's responsibility, to comply with the
requirements relating to ISOs. ISOs are not eligible for routing
pursuant to proposed Rule 21.9. A Market Order cannot be designated as
an Intermarket Sweep Order.\11\ Users may not designate bulk messages
as ISOs.
---------------------------------------------------------------------------

    \11\ The Exchange notes that the comparable description of ISOs
on BZX Options in BZX Rule 21.1(d)(9) does not specify that Market
Orders cannot be designated as ISOs, however, the Exchange believes
the proposed functionality is the same.
---------------------------------------------------------------------------

    The Exchange notes that, in contrast to BZX Options, it has
proposed characterizing Book Only, Post Only, and ISO as Handling
Instructions rather than Order Types, as each of these instructions
represents an additional modifier that can be appended to a Market
Order or Limit Order rather than a unique Order Type. The Exchange does
not believe that this characterization changes anything with respect to
the proposed operation of the Exchange but rather is a more accurate
characterization of the proposed functionality. The Exchange notes that
each of the proposed Order Types and Handling Instructions available on
MEMX Options is substantially similar to the same order type available
on BZX Options, except where described above or as relates to the
display-price sliding process offered by BZX Options, which the
Exchange is not proposing to adopt. The Exchange also notes that BZX
Options offers additional order types, such as reserve orders, minimum
quantity orders, price-improving orders, stop orders, and stop limit
orders, none of which the Exchange proposes to adopt.
    Time-in-Force Designations. Users entering orders into the System
may designate such orders to remain in force and available for display
and/or potential execution for varying periods of time. Unless
cancelled earlier, once these time periods expire, the order (or the
unexecuted portion thereof) is returned to the entering party. A Time-
in-Force applied to a bulk message applies to each bid and offer within
that bulk message. Unless otherwise specified in the Exchange Rules or
the context indicates otherwise, the Exchange determines which of the
following Times-in-Force are available on a class or system basis. The
Time-in-Force designations available on MEMX Options are described in
proposed Rule 21.1(f) and will include the following:
     Immediate Or Cancel (``IOC''). IOC means, for an order so
designated, an order that is to be executed in whole or in part as soon
as such order is received. The portion not so executed immediately on
the Exchange or another options exchange is cancelled and is not posted
to the MEMX Options Book. IOC orders that are not designated as Book
Only and that cannot be executed in accordance with proposed Rule 21.8
on the System when reaching the Exchange will be eligible for routing
away pursuant to proposed Rule 21.9. Users may designate bulk messages
as IOC.
     Day. Day means, for an order so designated, an order to
buy or sell which, if not executed expires at market close. Users may
designate bulk messages as Day.
    The Exchange notes that each of the proposed Time-in-Force
designations available on MEMX Options is identical to the same Time-
in-Force designation available on BZX Options, except that BZX Options
rules describe Time-in-Force designations as applicable only to limit
orders on BZX Options, whereas the Exchange has proposed allowing such
designations to be placed on both Limit Orders and Market Orders. The
Exchange also notes that BZX Options offers additional Times-in-Force,
such as good til cancelled, fill-or-kill, at the open, limit-on-close,
and market-on-close, none of which the Exchange proposes to adopt.
    Member Match Trade Prevention Modifiers. As with its equities
market, the Exchange will allow Users to use certain Match Trade
Prevention (``MTP'') modifiers, which are described in proposed Rule
21.1(g). Any incoming order designated with an MTP modifier will be
prevented from executing against a resting opposite side order also
designated with an MTP modifier and originating from the same EFID,
Exchange Member identifier, trading group identifier, or Exchange
Sponsored Participant identifier. The Exchange will offer the following
MTP modifiers: MTP Cancel Newest, described in proposed Rule
21.1(g)(1); MTP Cancel Oldest, described in proposed Rule 21.1(g)(2);
and MTP Cancel Both, described in proposed Rule 21.1(g)(3). The
Exchange notes that each of the proposed MTP modifiers available on
MEMX Options is identical to the same MTP modifier available on BZX
Options. The Exchange also notes that BZX Options offers additional MTP
modifiers, such as MTP Decrement and Cancel and MTP Cancel Smallest,
neither of which the Exchange proposes to adopt.
    Re-Pricing Mechanism. Like other options exchanges, the Exchange
proposes to offer a re-pricing mechanism to Users to comply with the
order protection and trade through restrictions of the Options Order
Protection and Locked/Crossed Market Plan. This re-pricing mechanism,
described in proposed Rule 21.1(i), is referred to by the Exchange as
Price Adjust and is identical to the Price Adjust mechanism offered by
BZX Options pursuant to BZX Rule 21.1(i), with the exception of the
handling of an order with a Post Only instruction subject to the Price
Adjust process. Whereas BZX Options applies the Price Adjust process
when a Post Only Order locks or crosses a Protected Quotation displayed
on BZX Options and re-prices such Post Only Order pursuant to BZX Rule
21.1(i)(4), the Exchange is not proposing to adopt this clause and
instead would cancel a Post Only Order that locks or crosses a
Protected Quotation displayed on MEMX Options. As noted above, the
Exchange is not proposing to offer a re-pricing mechanism equivalent to
the display-price sliding process offered by BZX Options.
    EFIDs. As proposed in Rule 21.1(j), the term ``EFIDs'' means
Executing Firm IDs and shall refer to what the System uses to identify
the User and the clearing number for the execution of orders and quotes
submitted to the System with that EFID. A User may obtain one or more
EFIDs from the Exchange (in a form and manner determined by the
Exchange). The Exchange assigns an EFID to its Users. Each EFID
corresponds to a single User and a single clearing number of a Clearing
Member with the Clearing Corporation. A User may obtain multiple EFIDs,
which may be for the same or different clearing numbers. A User is able
(in a form and manner determined by the Exchange) to designate which of
its EFIDs may be used for each of its ports. If a User submits an order
or quote through a port with an EFID not enabled for that port, the
System cancels or rejects the order or quote. The Exchange notes that
its proposed Rule 21.1(j) is identical to BZX Rule 21.1(k) other than
the use of the term ``User'' instead of ``Member.''
    Ports and Bulk Messages. Proposed Rule 21.1(k) defines two types of
ports:

(1) A``physical port,'' which provides a physical connection to the
System and may provide access to multiple logical ports; and (2) a
``logical port'' or ``application session,'' which provides Users with
the ability within the System to accomplish a specific function through
a connection, such as order entry, data receipt, or access to
information. The Exchange notes that each of the proposed types of
ports available on MEMX Options is identical to the same types of ports
on BZX Options, though instead of application session BZX Options also
refers to logical ports as logical sessions. The Exchange also notes
that BZX Options offers specific ports used for bulk messages whereas
the Exchange proposes to offer bulk message functionality through the
same logical ports as Users submit other messages to the Exchange.
Other than this distinction, the Exchange proposes to adopt the same
bulk message functionality as is offered by BZX Options. The term
``bulk message'' is proposed to mean a bid or offer included in a
single electronic message a User submits with a Market Maker Capacity
to the Exchange in which the User may enter, modify, or cancel up to an
Exchange-specified number of bids and offers (which number the Exchange
will announce via Exchange notice or publicly available technical
specifications). The System handles a bulk message in the same manner
as it handles an order or quote, unless the Exchange Rules specify
otherwise.\12\ Users may submit bulk messages through a logical port,
subject to the following: bulk messages must contain a Time-in-Force of
Day or IOC; a Market Maker with an appointment in a class must
designate a bulk message for that class as Post Only or Book Only, and
a non-appointed Market Maker must designate a bulk message for that
class as Post Only; the System cancels or rejects a Post Only bulk
message bid (offer) with a price that locks or crosses the Exchange
best offer (bid) or ABO (ABB); the System executes a Book Only bulk
message bid (offer) that locks or crosses the ABO (ABB) against offers
(bids) resting in the Book at prices the same as or better than the ABO
(ABB) and then cancels the unexecuted portion of that bid (offer).
---------------------------------------------------------------------------

    \12\ The Exchange notes that BZX Options maintains the
definition of bulk message in BZX Rule 16.1 whereas MEMX Options has
proposed to include this language in proposed Rule 21.1(l), where
bulk messages are further described. Despite this distinction, as
noted above, the functionality is the same other than the fact the
Exchange does not propose to require a separate bulk port to submit
bulk messages.
---------------------------------------------------------------------------

    Cancel Back. The term ``Cancel Back'' is proposed to mean an
instruction a User designates on an order (including bulk messages) to
not be subject to the Price Adjust process pursuant to proposed Rule
21.1(i). The System cancels or rejects an order with a Cancel Back
instruction (immediately at the time the System receives the order or
upon return to the System after being routed away) if displaying the
order on the Book would create a violation of proposed Rule 27.3, or if
the order cannot otherwise be executed or displayed in the Book at its
limit price. The System executes a Book Only--Cancel Back order against
resting orders. The proposed definition of Cancel Back in proposed Rule
21.1(m) is substantively identical to a Cancel Back Order defined in
BZX Rule 21.1(m), except as relates to the display-price sliding
process offered by BZX Options, which the Exchange is not proposing to
adopt, and the fact that the Exchange has not proposed to execute an
order with a Post Only instruction to the extent there is price
improvement associated with such execution (including if such order
also has a Cancel Back instruction).\13\
---------------------------------------------------------------------------

    \13\ See supra note 9 and accompanying text.
---------------------------------------------------------------------------

    Market Opening Procedures. As stated in proposed Rule 21.7, the
System shall open options, other than index options, for trading based
on the first transaction after 9:30 a.m. Eastern Time in the securities
underlying the options as reported on the first print disseminated
pursuant to an effective national market system plan. With respect to
index options, the System shall open for trading after a time period
(which the Exchange determines for all classes) following the System's
observation after 9:30 a.m. Eastern Time of the first disseminated
index value for the index underlying an index option. Because the
Exchange does not propose to adopt an opening cross or similar opening
process, the opening trade that occurs on the Exchange will be a trade
in the ordinary course of dealings on the Exchange. Accordingly, the
System will ensure that the opening trade in an options series will not
trade through a Protected Quotation at another options exchange,
consistent with the general standard regarding trade throughs
articulated in proposed Rule 21.6(e). The proposed market opening
procedures for options other than index options are identical to the
market opening procedures for such options that were initially adopted
by BZX Options.\14\ The proposed market opening procedures for index
options are substantially similar to the market opening procedures for
index options on BZX Options under current BZX Rule 21.7(d)(2) with
respect to when the System opens. However, once the BZX Options system
observes that an index value has been disseminated for the applicable
index BZX Options then commences an opening rotation (i.e., an opening
process to match liquidity at a price determined by the BZX Options
system) while the Exchange does not currently propose to adopt an
opening process. Additionally, the Exchange proposes that it may delay
the commencement of trading in any class of options in the interests of
a fair and orderly market. As stated in proposed Rule 21.6(c), orders
received prior to the opening of the System will be cancelled. The
Exchange believes that it is appropriate to commence operations on MEMX
Options with simplified procedures for when the System is open for
trading because for a successful opening process to function, an
exchange needs a critical mass of liquidity from market participants in
order to price and execute opening transactions. In turn, as a new
options exchange, MEMX Options does not know the amount of pre-opening
interest it will have, and it will have to gain market share in order
to accumulate such interest. MEMX Options will re-evaluate its opening
procedures over time and may propose to add an opening process through
a rule filing submitted to the Commission in the future.
---------------------------------------------------------------------------

    \14\ See Securities Exchange Act Release No. 61419 (January 26,
2010), 75 FR 5157 (February 1, 2010) (SR-BATS-2009-031) (Notice of
Filing of Amendment No. 1 and Order Granting Accelerated Approval of
a Proposed Rule Change, as Modified by Amendment No. 1 Thereto, To
Establish Rules Governing the Trading of Options on the BATS Options
Exchange).
---------------------------------------------------------------------------

    Order Display/Matching System. The System will be based upon
functionality currently approved for use in the Exchange's equities
trading system. Specifically, the System will allow Users to enter
Market Orders and priced Limit Orders to buy and sell MEMX Options-
listed options. All orders (including bulk messages) will be designated
for display (price and size) on an anonymous basis by the Exchange.
    Routing. The MEMX Options Exchange will support orders that are
designated to be routed to the National Best Bid and Offer (``NBBO'')
as well as orders that will execute only within MEMX Options. Orders
that are designated to execute at the NBBO will

be routed to other options markets to be executed when the Exchange is
not at the NBBO consistent with the Options Order Protection and
Locked/Crossed Market Plan. Subject to the exceptions contained in
proposed Rule 27.2(b), the System will ensure that an order will not be
executed at a price that trades through another options exchange. An
order that is designated by an Options Member as routable will be
routed in compliance with applicable trade-through restrictions. Any
order entered with a price that would lock or cross a Protected
Quotation that is not eligible for either routing or the price adjust
process as defined in proposed Rule 21.1(i) will be cancelled. Bulk
messages are not eligible for routing.
    The proposed routing functionality for MEMX Options is designed to
operate much like the routing functionality for the Exchange's equities
market, in that the Exchange offers a simple routing service to
facilitate compliance with applicable regulations and does not
currently offer other complex routing strategies. The Exchange notes
that the proposed rules relating to the routing of orders on MEMX
Options to away options markets are similar to the approved rules of
BZX Options, except that the Exchange proposes to cancel any unexecuted
portion of a Market Order after the System has routed to and received
response from an away options market, whereas BZX Options offers
additional handling instructions that may be chosen with respect to the
unexecuted portion of an order after the System has routed to and
received response from an away options market, and BZX Options offers
various additional routing options, such as routing to a specific
destination or at specified price levels.\15\
---------------------------------------------------------------------------

    \15\ See BZX Rule 21.9.
---------------------------------------------------------------------------

    MEMX Options shall route orders in options via MEMX Execution
Services LLC (``MEMX Execution Services''), which serves as the
Outbound Router of the Exchange, as defined in Rule 2.11. The function
of the Outbound Router will be to route orders in options listed and
open for trading on MEMX Options to other options exchanges pursuant to
the proposed rules of MEMX Options solely on behalf of MEMX Options.
The Outbound Router is subject to regulation as a facility of the
Exchange, including the requirement to file proposed rule changes under
Section 19 of the Act. Use of MEMX Execution Services or Routing
Services (as defined below) to route orders to other market centers is
optional. In the event the Exchange is not able to provide order
routing services through its affiliated broker-dealer, the Exchange
will route orders to other options exchanges in conjunction with one or
more routing brokers that are not affiliated with the Exchange
(``Routing Services''). Parties that do not desire to use MEMX
Execution Services or other Routing Services provided by the Exchange
must designate orders as not available for routing.
    In connection with the proposed rules regarding routing to away
options exchanges, proposed Rule 21.9(f) provides that MEMX Execution
Services has, pursuant to Rule 15c3-5 under the Act,\16\ implemented
certain tests designed to mitigate the financial and regulatory risks
associated with providing the Exchange's Users with access to such away
options exchanges. Pursuant to the policies and procedures developed by
MEMX Execution Services to comply with Rule 15c3-5, if an order or
series of orders are deemed to be erroneous or duplicative, would cause
the entering User's credit exposure to exceed a preset credit
threshold, or are non-compliant with applicable pre-trade regulatory
requirements (as defined in Rule 15c3-5), MEMX Execution Services will
reject such orders prior to routing and/or seek to cancel any orders
that have been routed. This is consistent with the routing
implementation of other options exchanges, and the Exchange notes that
proposed Rule 21.9(f) is substantively identical to BZX Rule 21.9(f).
---------------------------------------------------------------------------

    \16\ 17 CFR 240.15c3-5.
---------------------------------------------------------------------------

    Order Priority. The System, like the Exchange's equities facility,
shall execute trading interest within the System in price/time
priority, meaning it will execute all trading interest at the best
price level within the System before executing trading interest at the
next best price. Trading interest will be executed with the order
clearly established as the first entered into the System at each price
level having priority up to the number of contracts specified in the
order. Any order entered with a price that would lock or cross a
Protected Quotation that is not eligible for either routing or the
price adjust process as defined in proposed Rule 21.1(i) will be
cancelled. The Exchange notes that the proposed price/time order
priority and book processing is substantially similar to that on BZX
Options.
    Data Feed. The System will include a proprietary data feed which
will display without attribution to Users' orders on both the bid and
offer side of the market for price levels then within MEMX Options
using the minimum price variation applicable to that security.
    Risk Controls. The Exchange also proposes to offer to all Users of
MEMX Options the ability to establish certain risk control parameters
and limits that are intended to assist Users in managing their market
risk. The proposed risk controls are set forth in proposed Rules 21.16
and 21.17 and are based, in part, on those of BZX Options, with certain
additions and differences described below. The proposed risk controls
are designed to offer Users protection from entering orders outside of
certain size and price parameters, as well as certain standard or
Exchange-established parameters based on order type and market
conditions.
    The Exchange proposes to offer a Risk Monitor Mechanism described
in proposed Rule 21.16 that features passive risk counter
functionality, which is similar to the risk monitor mechanism
functionality offered by other options exchanges, including BZX
Options, as well as active risk counter functionality. Under the
proposed Risk Monitor Mechanism, Users may configure risk limits for
various parameters, including number of contracts executed
(``volume''), notional value of executions (``notional''), number of
executions (``count''), number of contracts executed as a percentage of
number of contracts outstanding within an Exchange-designated time
period or during the trading day (``percentage''), and the number of
times the limits on any of the foregoing parameters are reached (``risk
trips''). The System will track each of the parameters within an
underlying for an EFID (``underlying limit''), across all underlyings
for an EFID (``EFID limit''), across all underlyings for a group of
EFIDs (``EFID Group'') (``EFID Group limit''), and/or across a
customized group of orders designated by the User (``Custom Group
Limit''), over a User-established time period (``interval'') and on an
absolute basis for a trading day (``absolute limits'').
    When the System determines that a specified parameter has reached
the User-defined risk limit, depending on the User's instructions and
the applicable limit that has been reached, the Risk Monitor Mechanism
either: (1) Cancels or rejects such User's orders or quotes in all
series of the applicable underlying(s) and cancels or rejects any
additional orders or quotes from the User in the applicable
underlying(s) until the counting program resets; or (2) suspends all of
a User's resting orders or quotes in all series of the applicable
underlying(s) and cancels or rejects any additional orders or quotes
from the User in the applicable underlying(s) until the Exchange is
instructed to

reinstate such bids and offers. A User may also engage the Risk Monitor
Mechanism to cancel resting bids and offers, as well as subsequent
orders as set forth in proposed Rule 22.10 (``mass cancellation'') or
to suspend all resting bids and offers until the Exchange is instructed
to reinstate such bids and offers (``mass suspension'').
    The proposed Risk Monitor Mechanism functionality described above
is substantially similar to the risk monitor mechanism offered on BZX
Options, except that BZX Options does not permit Users to designate a
Custom Group Limit to track risk parameters across a customized group
of orders, nor does BZX Options permit Users to choose to suspend,
rather than cancel or reject, resting orders when a risk limit has been
reached or to engage the Risk Monitor Mechanism for mass suspension as
an alternative to mass cancellation. The Exchange believes that these
proposed additions to the Risk Monitor Mechanism functionality that is
currently available on BZX Options would provide Users with greater
optionality when managing their risk on MEMX Options.
    The proposed Risk Monitor Mechanism functionality described above
is similar to the Risk Monitor Mechanism functionality offered by other
options exchanges, including BZX Options, in that it provides for the
System to track specified risk parameters across designated underlyings
and/or order groups until the counting program is reset by the User
(such functionality, the ``passive risk counter''). In addition to the
Risk Monitor Mechanism's passive risk counter functionality, which is
similar to the Risk Monitor Mechanism functionality offered by BZX
Options in BZX Rule 21.16, the Exchange also proposes to enable a User
to optionally manage their risk limits actively using the Exchange's
proposed active risk counter functionality within the Risk Monitor
Mechanism. As proposed, for a User using the active risk counter, the
System will increment the active risk counter associated with a defined
parameter when such parameter increments, and the System will decrement
the active risk counter upon positive confirmation from the User via an
electronic instruction that the User has acknowledged a change in the
active risk counter. A User would also be able to specify the value by
which each parameter increments and decrements in the active risk
counter. The proposed active risk counter therefore enables a User to
interact with the Risk Monitor Mechanism dynamically such that the User
may actively acknowledge executions and decrement the counting program
by a specified amount as such executions occur (or at any time), rather
than waiting until a risk limit is reached or the User otherwise sends
a specific instruction to the Exchange to completely reset the counting
program.
    The following examples illustrate the proposed behavior of the
passive risk counter and the active risk counter within the Risk
Monitor Mechanism. In each case, assume a User configures a risk limit
of 10,000 contracts executed with respect to options contracts on
underlying security ABC for a single EFID.
    Passive Risk Counter:
     The System executes User's order to purchase 5,000 call
options on ABC (``Transaction 1''). The System's counting program would
increment to a total of 5,000 executed options contracts on ABC for the
User.
     The System then executes User's order to purchase 3,000
call options on ABC (``Transaction 2''). The System's counting program
would increment an additional 3,000 executed options contracts for
Transaction 2 to a total of 8,000 executed options contracts on ABC for
the User.
     The System then executes User's order to purchase 3,000
call options on ABC (``Transaction 3''). The System's counting program
would increment an additional 3,000 executed options contracts for
Transaction 3 to a total of 11,000 executed options contracts on ABC
for the User. As Transaction 3 results in executions in excess of the
User's risk limit with respect to the number of options contracts
executed, the Risk Monitor Mechanism is triggered, and the System will
cancel, reject or suspend, as applicable in accordance with the User's
instructions, the User's orders and quotes in all series of options
contracts on ABC for the User.
     The User then submits an electronic instruction to the
System to reset the counting program, and the counting program is
decremented to zero. The System will now accept new orders or quotes
from the User in a series of options contracts on ABC.
    Active Risk Counter:
     The System executes a transaction to purchase 5,000 call
options on ABC (``Transaction 1''). The System's counting program would
increment to a total of 5,000 executed options contracts on ABC for the
User.
     The User then submits an electronic instruction to the
System acknowledging a change in the active risk counter due to
Transaction 1. Upon the System's receipt of such instruction, the
counting program decrements the active risk counter by 5,000 options
contracts for Transaction 1 to a total of zero with respect to the
number of executed options contracts on ABC for the User.
     The System then executes two separate transactions to
purchase 3,000 call options on ABC per transaction (``Transaction 2''
and ``Transaction 3'' respectively), and the User does not acknowledge
a change in the active risk counter due to either of these executions.
The System's counting program would increment 3,000 executed options
contracts at the time of execution for each of Transaction 2 and
Transaction 3, for a total of 6,000 executed options contracts on ABC
for the User.
     The User then submits an electronic instruction to the
System acknowledging a change in the active risk counter due
Transaction 3, but not Transaction 2. Upon the System's receipt of such
instruction, the counting program would decrement the active risk
counter by the 3,000 executed options contracts for Transaction 3 to a
total of 3,000 executed options contracts on ABC for the User.
     The User then executes a transaction to purchase 10,000
call options on ABC (``Transaction 4''). The System's counting program
would increment an additional 10,000 executed options contracts for
Transaction 4 to a total of 13,000 options contracts on ABC for the
User. As Transaction 4 results in executions in excess of the User's
risk limit with respect to the number of options contracts executed,
the Risk Monitor Mechanism is triggered, and the System will cancel,
reject or suspend, as applicable in accordance with the User's
instructions, the User's orders and quotes in all series of options
contracts on ABC for the User.
     The User then submits an electronic instruction to the
System acknowledging a change in the active risk counter due to
Transaction 4. Upon the System's receipt of such instruction, the
counting program would decrement the active risk counter by the 10,000
executed options contracts for Transaction 4 to a total of 3,000
executed options contracts on ABC for the User. The System will now
accept new orders or quotes from the User in a series of options
contracts on ABC.
    In addition to the Risk Monitor Mechanism functionality described
above, the Exchange also proposes to offer additional price protection
mechanisms and risk controls that relate to certain standard or
Exchange-established parameters based on order type and market
conditions, which are

described in proposed Rule 21.17. These additional price protection
mechanisms and risk controls are substantially similar to those offered
on BZX Options pursuant to BZX Rule 21.17, with slight modifications to
align with the Exchange's proposed market opening procedures and
available order types and instructions on MEMX Options, except that the
Exchange is proposing a simplified version of the drill-through price
protection mechanism described in proposed Rule 21.17(d). Whereas the
drill-through price protection mechanism offered on BZX Options
pursuant to BZX Rule 21.17(d) executes an incoming order to a
determined ``Drill-Through Price'' and then displays the remainder of
the order on BZX Options at that price for a brief period of time, the
Exchange has proposed to simply cancel the remainder of an incoming
order after executing the order to the Drill-Through Price.
    One Second Exposure Period. Proposed Rule 22.11 would require
Options Members to expose their customers' orders on the Exchange for
at least one second under certain circumstances. During this one second
exposure period, other Options Members will be able to enter orders to
trade against the exposed order. In adopting a one second order
exposure period, the Exchange is proposing a requirement that is
consistent with the rules of other options exchanges.\17\ Thus, the
exposure period will allow Options Members that are members of other
options exchanges to comply with proposed Rule 22.11 without
programming separate time parameters into their systems for order entry
or compliance purposes. The Exchange believes that market participants
are sufficiently automated that a one second exposure period allows an
adequate time for market participants to electronically respond to an
order. Also, it is possible that market participants might wait until
the end of the exposure period, no matter how long, before responding.
Thus, the Exchange believes that any longer than one second would not
further the protection of investors or market participants, but rather,
would potentially increase market risk to investors and other market
participants by creating a longer period of time for the exposed order
to be subject to market risk.

Options Order Protection and Locked/Crossed Market Plan Rules
    The Exchange will participate in the Options Order Protection and
Locked/Crossed Market Plan (the ``Plan''), and therefore will be
required to comply with the obligations of Participants under the Plan.
The Exchange proposes to adopt rules relating to the Plan that are
substantially similar to the rules in place on all of the options
exchanges that are Participants to the Plan. The Plan essentially
applies the Regulation NMS price-protection provisions to the options
markets. Similar to Regulation NMS, the Plan requires the Plan
Participants to adopt rules ``reasonably designed to prevent Trade-
Throughs'', while exempting ISOs from that prohibition. The Plan's
definition of an ISO is essentially the same as under Regulation NMS.
The remaining exceptions to the trade-through prohibition, discussed
more specifically below, either track those under Regulation NMS or
correspond to unique aspects of the options market, or both.
    The proposed rules in Chapter 27 (Options Order Protection and
Locked and Crossed Markets Rules) conform to the requirements of the
Plan. Proposed Rule 27.1 sets forth the defined terms for use under the
Plan. Proposed Rule 27.2 prohibits trade-throughs and exempts ISOs from
that prohibition. Proposed Rule 27.2 also contains additional
exceptions to the trade-through prohibition that track the exceptions
under Regulation NMS or correspond to unique aspects of the options
market, or both.
    Proposed Rule 27.3 sets forth the general prohibition against
locking/crossing other eligible exchanges as well as certain enumerated
exceptions that permit locked markets in limited circumstances; such
exceptions have been approved by the Commission for inclusion in the
rules of other options exchanges. Specifically, the exceptions to the
general prohibition on locking and crossing occur when: (1) The locking
or crossing quotation was displayed at a time when the Exchange was
experiencing a failure, material delay, or malfunction of its systems
or equipment; (2) the locking or crossing quotation was displayed at a
time when there is a Crossed Market; or (3) the Options Member
simultaneously routed an ISO to execute against the full displayed size
of any locked or crossed Protected Bid or Protected Offer.
    The Exchange notes that the proposed rules in Chapter 27 (Options
Order Protection and Locked and Crossed Markets Rules) are
substantively identical to the rules of BZX Options.\18\
---------------------------------------------------------------------------

    \18\ See BZX Rules, Chapter XXVII.
---------------------------------------------------------------------------

Securities Traded on MEMX Options
    General Listing Standards. The Exchange proposes to adopt listing
standards for options traded on MEMX Options as described in Chapter 19
(Securities Traded on MEMX Options), as well as for index options as
described in Chapter 29 (Index Rules), which are substantively
identical to the approved rules of BZX Options.\19\ The Exchange will
join the Options Listings Procedures Plan and will list and trade
options already listed on other options exchanges. The Exchange will
gradually phase-in its trading of options, beginning with a selection
of actively traded options. At least initially, the Exchange does not
plan to develop new options products or listing standards.
---------------------------------------------------------------------------

    \19\ See BZX Rules, Chapters XIX and XXIX. The Exchange notes
that it is initially proposing to adopt rules applicable to listing
and trading of index options but has not proposed inclusion of
references to any specific index options products or indices at this
time and therefore has included a placeholder with the rule text
``(Reserved.)'' where such references would otherwise be. To the
extent the Exchange does propose to list and trade certain index
products in the future, the Exchange will file a proposed rule
change with the Commission with respect to such products.
---------------------------------------------------------------------------

Conduct and Operational Rules for Options Members
    The Exchange proposes to adopt rules for MEMX Options that are
substantively identical to the rules of BZX Options regarding:
Exercises and deliveries as described in Chapter 23 (Exercises and
Deliveries); records, reports and audits as described in Chapter 24
(Records, Reports and Audits); minor rule violations as described in
Chapter 25 (Discipline and Summary Suspensions); doing business with
the public as described in Chapter 26 (Doing Business With the Public);
and margin as described in Chapter 28 (Margin Requirements).\20\
---------------------------------------------------------------------------

    \20\ See BZX Rules, Chapters XXIII, XXIV, XXV, XXVI and XXVIII.
---------------------------------------------------------------------------

National Market System
    MEMX Options will operate as a full and equal participant in the
national market system for options trading established under Section
11A of the Exchange Act,\21\ just as its equities market participates
today. MEMX Options will become a member of the Options Price Reporting
Authority (``OPRA''), the Options Linkage Authority (``OLA''), the
Options Regulatory Surveillance Authority (``ORSA''), and the Options
Listing Procedures Plan (``OLPP''). The Exchange expects to participate
in those plans on the same terms currently applicable to current
members of those

plans. The Exchange has contacted the leadership of each options-
related national market system plan to begin the membership process.

---------------------------------------------------------------------------

Regulation
    The Exchange will leverage many of the structures it established to
operate a national securities exchange in compliance with Section 6 of
the Exchange Act.\22\ As described in more detail below, there will be
three elements of that regulation: (1) The Exchange will join the
existing options industry agreements pursuant to Section 17(d) of the
Exchange Act,\23\ as it did with respect to equities; (2) the
Exchange's Regulatory Services Agreement with FINRA will govern many
aspects of the regulation and discipline of Members that participate in
options trading, just as it does for equities regulation; and (3) the
Exchange will perform options listing regulation, as well as authorize
Options Members to trade on MEMX Options, and conduct surveillance of
options trading as it does today for equities. Section 17(d) of the
Exchange Act and the related Exchange Act rules permit SROs to allocate
certain regulatory responsibilities to avoid duplicative oversight and
regulation. Under Exchange Act Rule 17d-1,\24\ the SEC designates one
SRO to be the Designated Examining Authority, or DEA, for each broker-
dealer that is a member of more than one SRO. The DEA is responsible
for the financial aspects of that broker-dealer's regulatory oversight.
Because MEMX Options Members also must be members of at least one other
SRO, the Exchange would generally not be designated as the DEA for any
of its members.

    \24\ 17 CFR 240.17d-1.
---------------------------------------------------------------------------

    Exchange Act Rule 17d-2 \25\ permits SROs to file with the
Commission plans under which the SROs allocate among each other the
responsibility to receive regulatory reports from, and examine and
enforce compliance with specified provisions of the Exchange Act and
rules thereunder and SRO rules by, firms that are members of more than
one SRO (``common members''). If such a plan is declared effective by
the Commission, an SRO that is a party to the plan is relieved of
regulatory responsibility as to any common member for whom
responsibility is allocated under the plan to another SRO.
---------------------------------------------------------------------------

    \25\ 17 CFR 240.17d-2.
---------------------------------------------------------------------------

    All of the options exchanges, FINRA, and NYSE have entered into the
Options Sales Practices Agreement, a Rule 17d-2 agreement. Under this
Agreement, the examining SROs will examine firms that are common
members of the Exchange and the particular examining SRO for compliance
with certain provisions of the Exchange Act, certain of the rules and
regulations adopted thereunder, certain examining SRO rules, and
certain proposed MEMX Options rules. In addition, the proposed MEMX
Options rules contemplate participation in this Agreement by requiring
that any Options Member also be a member of at least one of the
examining SROs.
    For those regulatory responsibilities that fall outside the scope
of any Rule 17d-2 agreements, the Exchange will retain full regulatory
responsibility under the Exchange Act. However, the Exchange has
entered into a Regulatory Services Agreement with FINRA, pursuant to
which FINRA personnel operate as agents for the Exchange in performing
certain of these functions. As is the case with the Exchange's equities
market, the Exchange will supervise FINRA and continue to bear ultimate
regulatory responsibility for the MEMX Options Exchange.
    Consistent with the Exchange's existing regulatory structure, the
Exchange's Chief Regulatory Officer shall have general supervision of
the regulatory operations of MEMX Options, including responsibility for
overseeing the surveillance, examination, and enforcement functions and
for administering all regulatory services agreements applicable to MEMX
Options. Similarly, the Exchange's existing Regulatory Oversight
Committee will be responsible for overseeing the adequacy and
effectiveness of Exchange's regulatory and self-regulatory organization
responsibilities, including those applicable to MEMX Options.
    Finally, as it does with equities, the Exchange will perform
automated surveillance of trading on MEMX Options for the purpose of
maintaining a fair and orderly market at all times. As it does with its
equities trading, the Exchange will monitor MEMX Options to identify
unusual trading patterns and determine whether particular trading
activity requires further regulatory investigation by FINRA.
    In addition, the Exchange will oversee the process for determining
and implementing trade halts, identifying and responding to unusual
market conditions, and administering the Exchange's process for
identifying and remediating ``obvious errors'' by and among its Options
Members. The proposed rules in Chapter 20 (Regulation of Trading on
MEMX Options) regarding halts, unusual market conditions, extraordinary
market volatility, obvious errors, and audit trail are substantively
identical to the approved rules of BZX Options, with the exception that
Exchange does not propose to include rules permitting certain off-floor
transfers of options traded on MEMX Options.\26\
---------------------------------------------------------------------------

    \26\ See BZX Rules, Chapter XX.
---------------------------------------------------------------------------

Minor Rule Violation Plan
    The Exchange's disciplinary rules, including Exchange Rules
applicable to ``minor rule violations,'' are set forth in Chapter 8 of
the Exchange's current Rules. Such disciplinary rules will apply to
Options Members and their associated persons.
    The Commission approved the Exchange's Minor Rule Violation Plan
(``MRVP'') in 2020.\27\ The Exchange's MRVP specifies those uncontested
minor rule violations with sanctions not exceeding $2,500 that would
not be subject to the provisions of Rule 19d-1(c)(1) under the Act \28\
requiring that an SRO promptly file notice with the Commission of any
final disciplinary action taken with respect to any person or
organization.\29\ The Exchange's MRVP includes the policies and
procedures included in Exchange Rule 8.15 (Imposition of Fines for
Minor Violation(s) of Rules) and in Exchange Rule 8.15, Interpretations
and Policy .01.
---------------------------------------------------------------------------

    \27\ See Release No. 34-89836 (September 11, 2020), 85 FR 58081
(September 17, 2020) (Order Declaring Effective a Minor Rule
Violation Plan) (``MRVP Order'').
    \28\ 17 CFR 240.19d-1(c)(1).
    \29\ The Commission adopted amendments to paragraph (c) of Rule
19d-1 to allow SROs to submit for Commission approval plans for the
abbreviated reporting of minor disciplinary infractions. See Release
No. 34-21013 (June 1, 1984), 49 FR 23828 (June 8, 1984). Any
disciplinary action taken by an SRO against any person for violation
of a rule of the SRO which has been designated as a minor rule
violation pursuant to such a plan filed with and declared effective
by the Commission will not be considered ``final'' for purposes of
Section 19(d)(1) of the Act if the sanction imposed consists of a
fine not exceeding $2,500 and the sanctioned person has not sought
an adjudication, including a hearing, or otherwise exhausted his
administrative remedies.
---------------------------------------------------------------------------

    The Exchange proposes to amend its MRVP and Exchange Rule 8.15,
Interpretation and Policy .01 to include proposed Rule 25.3 (Penalty
for Minor Rule Violations).\30\ The rules included in proposed Rule
25.3 as appropriate for disposition under the Exchange's MRVP are: (a)
Position limit and exercise limit violations; (b) violations regarding
the

failure to accurately report position and account information; (c)
Market Maker quoting obligations; (d) violations regarding expiring
exercise declarations; (e) violations relating to the failure to
respond to the Exchange's requests for the submission of trade data;
and (f) violations relating to noncompliance with the Consolidated
Audit Trail Compliance Rule requirements. The rules included in
proposed Rule 25.3 are the same as the rules included in the MRVPs of
other options exchanges.\31\
---------------------------------------------------------------------------

    \30\ In its proposal to adopt the MRVP, the Exchange requested
that, going forward, to the extent that there are any changes to the
rules applicable to the Exchange's MRVP, the Exchange requests that
the Commission deem such changes to be modifications to the
Exchange's MRVP.
    \31\ See, e.g., BZX Rules, Chapter XXV.
---------------------------------------------------------------------------

    Upon implementation of this proposal, the Exchange will include the
enumerated options trading rule violations in the Exchange's standard
quarterly report of actions taken on minor rule violations under the
MRVP. The quarterly report includes: The Exchange's internal file
number for the case, the name of the individual and/or organization,
the nature of the violation, the specific rule provision violated, the
fine imposed, the number of times the rule violation has occurred, and
the date of disposition. The Exchange's MRVP, as proposed to be
amended, is consistent with Sections 6(b)(1), 6(b)(5) and 6(b)(6) of
the Act, which require, in part, that an exchange have the capacity to
enforce compliance with, and provide appropriate discipline for,
violations of the rules of the Commission and of the exchange.\32\ In
addition, because amended Rule 8.15 will offer procedural rights to a
person sanctioned for a violation listed in proposed Rule 25.3, the
Exchange will provide a fair procedure for the disciplining of members
and associated persons, consistent with Section 6(b)(7) of the Act.\33\
---------------------------------------------------------------------------

    \32\ 15 U.S.C. 78f(b)(1), 78f(b)(5) and 78f(b)(6).
    \33\ 15 U.S.C. 78f(b)(7).
---------------------------------------------------------------------------

    This proposal to include the rules listed in proposed Rule 25.3 in
the Exchange's MRVP is consistent with the public interest, the
protection of investors, or otherwise in furtherance of the purposes of
the Act, as required by Rule 19d-1(c)(2) under the Act,\34\ because it
should strengthen the Exchange's ability to carry out its oversight and
enforcement responsibilities as an SRO in cases where full disciplinary
proceedings are unsuitable in view of the minor nature of the
particular violation. In requesting the proposed change to the MRVP,
the Exchange in no way minimizes the importance of compliance with
Exchange Rules and all other rules subject to the imposition of fines
under the MRVP. However, the MRVP provides a reasonable means of
addressing rule violations that do not rise to the level of requiring
formal disciplinary proceedings, while providing greater flexibility in
handling certain violations. The Exchange will continue to conduct
surveillance with due diligence and make a determination based on its
findings, on a case-by-case basis, whether a fine of more or less than
the recommended amount is appropriate for a violation under the MRVP or
whether a violation requires a formal disciplinary action.

Amendments to Existing Exchange Rules
    In addition to the rules of MEMX Options proposed above, the
Exchange proposes to amend certain of its existing Exchange Rules that
currently apply to the Exchange's equities market in order to reflect
the Exchange's proposed operation of MEMX Options.
    First, the Exchange proposes to amend paragraph (d) of
Interpretations and Policies .01 to Rule 2.5 (Restrictions), which
generally requires each Member to register at least two Principals with
the Exchange subject to certain exceptions described therein, to
provide that such paragraph (d) shall not apply to a Member that solely
conducts business on the Exchange as an Options Member, however,
Options Members must comply with the registration requirements set
forth in proposed Rule 17.2(g). The Exchange notes that proposed Rule
17.2(g), which provides that every Options Member shall have at least
one Options Principal and sets forth the Exchange's Options Principal
registration requirements, is identical to BZX Rule 17.2(g). In
connection with this proposed change, the Exchange also proposes to
amend paragraph (i) of Interpretations and Policies .01 to Rule 2.5 to
include Options Principal as a registration category and to set forth
the Exchange's qualification requirements for an Options Principal,
which are the same as those for an Options Principal on BZX Options.
    The Exchange also proposes to delete the word ``equities'' in the
first sentence of Rule 2.7 (Revocation of Membership or Association
with a Member), which currently provides that Members or associated
persons of Members may effect approved equities securities transactions
on the Exchange's trading facilities only so long as they possess all
the qualifications set forth in the Exchange Rules. Thus, such proposed
change is intended to make this statement no longer limited to equities
securities transactions, as options transactions may also be effected
on the Exchange pursuant to this proposal.
    Lastly, the Exchange proposes to amend Interpretations and Policies
.01 Rule 8.15 (Imposition of Fines for Minor Violation(s) of Rules),
which contains the list of Exchange Rule violations and recommended
fine schedule pursuant to Rule 8.15, to include a new paragraph (i)
referencing proposed Rule 25.3 for the recommended fines for minor rule
violations of the Exchange Rules appliable [sic] to MEMX Options, which
the Exchange notes are the same as those of BZX Options.
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent
with Section 6(b) of the Act \35\ in general, and furthers the
objectives of Section 6(b)(5) of the Act \36\ in particular, in that it
is designed to prevent fraudulent and manipulative acts and practices,
to promote just and equitable principles of trade, to foster
cooperation and coordination with persons engaged in regulating,
clearing, settling, processing information with respect to, and
facilitating transactions in securities, to remove impediments to and
perfect the mechanism of a free and open market and a national market
system, and, in general, to protect investors and the public interest;
and is not designed to permit unfair discrimination between customers,
issuers, brokers, or dealers.
---------------------------------------------------------------------------

    \35\ 15 U.S.C. 78f(b).
    \36\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    As described above, the fundamental premise of the proposal is that
the Exchange will operate its options market much as it operates its
cash equities market today and in a manner similar to that of other
options exchanges, with a simplified suite of order types and
deterministic functionality leveraging the Exchange's existing robust
and resilient technology platform. The Exchange believes MEMX Options
will benefit individual investors, options trading firms, and the
options market generally by providing an additional competitive dynamic
to the options landscape, thereby promoting further initiative and
innovation among market centers and market participants. The entry of
an innovative, cost competitive market such as MEMX Options will
promote competition, spurring existing exchanges to improve their own
executions systems and reduce trading costs.
    The Exchange proposes to offer a simplified suite of conventional
order types and order type modifiers and other instructions that are
designed to provide for an efficient, robust, and transparent order
matching process. The

basis for a majority of the proposed rules of MEMX Options are the
approved rules of other options exchanges, primarily BZX Options, which
have already been found consistent with the Exchange Act. Therefore,
the Exchange does not believe that any of the proposed order types and
order type functionality raise any new or novel issues that have not
been previously considered by the Commission.
    In few instances where the Exchange proposes functionality that
differs from that of other options exchanges, it has done so to
simplify and/or to improve upon an existing process. For instance, the
Exchange believes the proposed operation of the Exchange's Risk Monitor
Mechanism described in Rule 21.16, including the proposed functionality
in addition to that provided under BZX Rule 21.16, removes impediments
to and perfects the mechanism of a free and open market and a national
market system by offering Users additional ways to establish and
monitor risk parameters consistent with their overall approach to risk
management. Specifically, the following additional proposed features
with respect to its Risk Monitor Mechanism would provide Users with
greater optionality when managing their risk on MEMX Options: (i) The
ability to designate a Custom Group Limit to track risk parameters
across a customized group of orders, (ii) the ability to suspend,
rather than cancel or reject, resting orders when a risk limit has been
reached, (iii) the ability to engage the Risk Monitor Mechanism for
mass suspension as an alternative to mass cancellation, and (iv) the
ability to utilize the proposed active risk counter to actively
acknowledge executions, rather than waiting until a risk limit is
reached or the counting program is completely reset. Additionally, the
Exchange believes proposed Rule 21.17, which contains standard and
Exchange-determined risk controls based on order type and market
conditions that are the same as other options exchanges, as well as a
simplified version of the drill-through price protection mechanism,
removes impediments to and perfects the mechanism of a free and open
market and a national market system by imposing risk controls that are
designed to prevent orders from executing at prices inconsistent with
the current market.
    The Exchange further believes that the functionality that it
proposes to offer is consistent with Section 6(b)(5) of the Act because
the System is designed to be efficient and its operation transparent,
thereby facilitating transactions in securities, removing impediments
to and perfecting the mechanisms of a free and open national market
system. As described above, the Exchange's proposed rules, including
the proposed Order Types and Handling Instructions, opening procedures,
routing services, and order matching process are designed to provide a
simplified suite of conventional features and to comply with all
applicable regulatory requirements, including the obligations of the
Options Order Protection and Locked/Crossed Market Plan.
    The Exchange believes that the proposed rules of MEMX Options, as
well as the proposed method of monitoring for compliance with and
enforcing such rules is also consistent with the Exchange Act,
particularly Sections 6(b)(1), 6(b)(5) and 6(b)(6) of the Exchange Act,
which require, in part, that an exchange have the capacity to enforce
compliance with, and provide appropriate discipline for, violations of
the rules of the Commission and of the exchange. The Exchange has
proposed to adopt rules necessary to regulate Options Members that are
nearly identical to the approved rules of other options exchanges, as
described above. The Exchange proposes to regulate activity on MEMX
Options in the same way it regulates activity on its equities market,
specifically through various Exchange specific functions, an RSA with
FINRA, as well as participation in industry plans, including plans
pursuant to Rule 17d-2 under the Exchange Act.

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will
result in any burden on competition that is not necessary or
appropriate in furtherance of the purposes of the Act. The Exchange
operates in an intensely competitive global marketplace for transaction
services. Relying on its array of services and benefits, the Exchange
competes for the privilege of providing market services to broker-
dealers. The Exchange's ability to compete in this environment is based
in large part on the quality of its trading systems, the overall
quality of its market and its attractiveness to the largest number of
investors, as measured by speed, likelihood and cost of executions, as
well as spreads, fairness, and transparency.
    Consolidation amongst U.S. options exchanges has led to
concentration of ownership by certain exchange groups, thereby
diminishing the competitive landscape among options exchanges. This
proposal will enhance competition by allowing the Exchange to leverage
its existing robust technology platform to provide a resilient,
deterministic, and transparent execution platform for options. The
proposed rule change will insert an additional competitive dynamic to
the options landscape by allowing the Exchange to compete with existing
options exchanges and will promote further initiative and innovation
among market centers and market participants.

C. Self-Regulatory Organization's Statement on Comments on the Proposed
Rule Change Received From Members, Participants, or Others

    The Exchange neither solicited nor received comments on the
proposed rule change.

III. Date of Effectiveness of the Proposed Rule Change and Timing for
Commission Action

    Within 90 days of the date of publication of this notice in the
Federal Register, the Commission shall: (a) By order approve or
disapprove such proposed rule change, or (b) institute proceedings to
determine whether the proposed rule change should be disapproved.\37\
---------------------------------------------------------------------------

    \37\ In its filing, MEMX consented to an extension of time for
Commission action to ninety (90) days after the date of publication
of the proposal.
