I. Self-Regulatory Organization's Description of the Proposed Rule
Change

    The Exchange proposes to provide additional guidance in its rules
regarding prohibited disruptive practices.
    The rule amendments included as part of this proposed rule change
are to apply to all products traded on CFE, including both non-security
futures and any security futures that may be listed for trading on CFE.
The scope of this filing is limited solely to the application of the
proposed rule change to security futures that may be traded on CFE.
Although no security futures are currently listed for trading on CFE,
CFE may list security futures for trading in the future.
    The text of the proposed rule change is attached as Exhibit 4 to
the filing but is not attached to the publication of this notice.

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

    In its filing with the Commission, CFE 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. CFE 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

1. Purpose
    CFE Rule 620 (Disruptive Practices) prohibits various disruptive
practices and CFE Policy and Procedure XVIII (Disruptive Trading
Practices) (``P&P XVIII'') of the Policies and Procedures section of
the CFE Rulebook lists various factors that CFE may consider in
assessing whether conduct violates Rule 620. The proposed rule change
proposes to make the following clarifying updates in relation to these
provisions.
    CFE is proposing to amend the provisions of Section E of P&P XVIII
in the following manner.
    The title of Section E of P&P XVIII is currently ``Orders entered
by mistake.'' The proposed rule change proposes to revise the title of
Section E of P&P XVIII to be ``Orders entered by mistake or error'' to
clarify that Section E of P&P XVIII covers Orders entered either by
mistake or error. The Exchange considers the terms ``mistake'' and
``error'' to be synonyms for one another while recognizing that a
mistake may be more associated with human action while an error may be
more associated with system behavior. To the extent that there is a
difference between the two terms and that Section E of P&P XVIII refers
to ``errors'' within the text of the provision, the Exchange is making
this change to make clear that a mistake is encompassed within the
references to ``errors'' in the text of the provision.
    The first sentence of Section E of P&P XVIII currently provides
that: ``An unintentional, accidental, or `fat-finger' Order will not
constitute a violation of Rule 620, but such activity may be a
violation of other Exchange rules, including, but not limited to, Rule
608 (Acts Detrimental to the Exchange; Acts Inconsistent with Just and
Equitable Principles of Trade; Abusive Practices).'' The proposed rule
change proposes to insert the word ``typically'' after the word ``not''
so that the sentence provides that an unintentional, accidental, or
``fat-finger'' Order will not typically constitute a violation of Rule
620, but such activity may be a violation of other Exchange rules,
including, but not limited to, Rule 608.
    The second sentence of Section E of P&P XVIII currently provides
that: ``Market participants are expected to take steps to mitigate the
occurrence of errors, and their impact on the market.'' The proposed
rule change proposes to further flesh out this sentence by revising it
to provide that: ``Market participants are expected to take reasonable
steps or otherwise have controls to prevent, detect and mitigate the
occurrence of errors, market disruptions and system anomalies and their
impact on the market.'' This proposed additional language clarifies
that market participants are expected to take reasonable steps or to
otherwise have controls in place to prevent, detect, and mitigate the
occurrence of errors, market disruptions and system anomalies, and
their impact on the market.
    The proposed rule change proposes to add the following sentence at
the end of Section E of P&P XVIII in reference to the second sentence
of Section E of P&P XVIII: ``Failure to take reasonable steps to
prevent, detect and mitigate such errors, market disruptions, system
anomalies or impacts may violate Rule 609 (Supervision) or other
Exchange rules.'' This sentence is intended to provide additional
clarity to market participants about how P&P XVIII interacts with other
CFE rules.
    Section K of P&P XVIII describes factors that may be considered in
determining whether a market participant intended to disrupt the
orderly conduct of trading or the fair execution of transactions or
demonstrated a reckless disregard for the orderly conduct of trading or
the fair execution of transactions. CFE is proposing to amend Section K
of P&P XVIII to provide that additional factors that may be considered
in this regard include, but are not limited to, the impact to other
market participants' ability to trade, engage in price discovery, or
manage risk. CFE believes that the addition of these added non-
exhaustive factors will provide further clarity regarding how CFE
determines whether a market participant intended to disrupt, or
demonstrated a reckless disregard for, the orderly conduct of trading
or the fair execution of transactions.
    CFE also proposes to make the following clarifying updates to the
provisions of Section U of P&P XVIII.
    The title of Section U of P&P XVIII is currently ``Submission of
partial messages to reduce latency or purposeful corruption of data
packets.'' The proposed rule change proposes to revise the title of
Section U of P&P XVIII to be ``Submission of partial messages to reduce
latency or purposeful submission of intentionally corrupted or
malformed data packets.''
    The second sentence of Section U of P&P XVIII currently provides
that: ``Purposefully corrupting or constructing malformed data packets
also has the potential to disrupt the systems of the Exchange.'' The
proposed rule change proposes to revise this sentence to provide that:
``Purposefully submitting intentionally corrupted or malformed data
packets also has the potential to disrupt the systems of the
Exchange.''
    The proposed revisions to Section U of P&P XVIII are intended
clarify that activity within the scope of Section U of P&P XVIII
relating to corrupted or malformed data packets involves the purposeful
submission of intentionally corrupted or malformed data packets.
    CFE also is proposing to add an example of prohibited activity
under Rule 620. In particular, P&P XVIII includes a non-exhaustive list
of various examples of conduct that may be found to violate Rule 620.
The additional example provides a specific illustration of a trading
strategy that may violate Rule 620 which involves purposefully
submitting malformed data packets to CFE's trading system (``CFE
System'') as part of a trading strategy to reduce latency. In
particular, this type of trading strategy may violate Rule 620(b)(iv)
which provides that no Person shall intentionally or recklessly submit
or cause to be submitted an actionable or non-actionable message(s)
that has the potential to disrupt the systems of the Exchange or other
market participants.
    The proposed additional example includes the following fact
pattern: A market participant engages in a trading strategy where the
market participant's trading system is designed to purposefully submit
malformed data across one or more physical connections to the Exchange.
For example, based on information received, the participant's trading
system begins constructing an order message (e.g., an Ethernet Frame,
TCP or IP packet, etc.). The trading system is designed so that if
further information is received during construction that negates the
desire or need to trade the order being constructed, the trading system
will stop construction and submit the incomplete data to the Exchange.

Because the incomplete data (e.g., a TCP/IP packet missing required TCP
or IP fields such as Sequence Number or Destination Port) cannot be
properly processed by a network switch or receiving device at the
logical or physical entry point to the CFE System, the receiving device
will discard the data. If no further information is received by the
trading system during construction that would negate the desire or need
to trade the order, the trading system will complete construction of,
and submit, the data so that an Order message from the trading system
is able to reach the CFE System. The practice of submitting to the
Exchange purposefully incomplete or malformed data packets has the
potential to disrupt the systems of the Exchange and may violate Rule
620(b)(iv).
    The purposeful submission of intentionally corrupted or malformed
data packets has the potential to impact the systems of the Exchange
and the Exchange believes that this activity serves no useful purpose.
Accordingly, the proposed rule change further clarifies how this type
of activity may violate Rule 620 and P&P XVIII.
    The proposed rule change is consistent with similar updated
guidance provided by other designated contract markets (``DCMs'')
regarding disruptive practices.\3\ The Exchange believes that aligning
its guidance regarding disruptive trading practices across DCMs where
appropriate protects the Exchange, investors, and the public interest
by promoting uniform expectations among market participants regarding
disruptive trading practices.
---------------------------------------------------------------------------

    \3\ These DCMs are ICE Futures U.S., Inc. (``ICE''), Chicago
Mercantile Exchange, Inc. (``CME''), The Board of Trade of the City
of Chicago, Inc., New York Mercantile Exchange, Inc., and Commodity
Exchange, Inc. Each submitted rule certification filings to the CFTC
to effectuate their respective updated guidance. See, e.g., ICE
Submission 21-44 (June 22, 2021) and CME Submission No. 20-306 (July
16, 2021), which are available on the CFTC website.
---------------------------------------------------------------------------

    CFE also believes that the proposed rule change is consistent with
the Electronic Trading Risk Principles recently adopted by the CFTC.\4\
The Electronic Trading Risk Principles are intended to address the
potential risk of a DCM's trading platform experiencing a market
disruption or system anomaly due to electronic trading. For example,
CFTC Regulation 38.251(e) \5\ provides that a DCM must adopt and
implement rules governing market participants subject to its
jurisdiction to prevent, detect, and mitigate market disruptions or
system anomalies associated with electronic trading. The proposed rule
change furthers the goals of the Electronic Trading Risk Principles by
making clear, among other things, (i) that market participants are
expected to take reasonable steps or otherwise have controls to
prevent, detect, and mitigate the occurrence of errors, market
disruptions, and system anomalies and their impact on the market and
(ii) that factors which may be considered in determining whether a
market participant intended to disrupt, or demonstrated a reckless
disregard for, the orderly conduct of trading or the fair execution of
transactions include, but are not limited to, the impact to other
market participants' ability to trade, engage in price discovery, or
manage risk.
---------------------------------------------------------------------------

    \4\ See CFTC Final Rule regarding Electronic Trading Risk
Principles, 86 FR 2048 (January 11, 2021).
    \5\ 17 CFR 38.251(e).
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent
with Section 6(b) of the Act,\6\ in general, and furthers the
objectives of Sections 6(b)(1) \7\ and 6(b)(5) \8\ in particular, in
that it is designed:
---------------------------------------------------------------------------

    \6\ 15 U.S.C. 78f(b).
    \7\ 15 U.S.C. 78f(b)(1).
    \8\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

     To enable the Exchange to enforce compliance by its
Trading Privilege Holders and persons associated with its Trading
Privilege Holders with the provisions of the rules of the Exchange,
     to prevent fraudulent and manipulative acts and practices,
     to promote just and equitable principles of trade,
     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.
    The proposed rule change provides additional guidance regarding
disruptive practices that violate CFE Rule 620. CFE considers the
disruptive trading practices addressed by the proposed rule change to
be prohibited by existing CFE rules, including current Rule 620, P&P
XVIII, CFE Rule 608 (Acts Detrimental to the Exchange, Acts
Inconsistent with Just and Equitable Principles of Trade; Abusive
Practices) and CFE Rule 609 (Supervision). CFE also considers the
provisions that are proposed to be added to P&P XVIII relating to
factors that the Exchange may consider in assessing whether conduct
violates Rule 620 and relating to purposefully submitting intentionally
corrupted or malformed data packets to be within the scope of existing
CFE rules, including current Rule 620 and P&P XVIII. Although this is
the case, CFE believes that it is beneficial to provide additional
guidance to market participants through the inclusion of further detail
in CFE's rules regarding prohibited disruptive practices.
    By further describing prohibited disruptive trading practices in
CFE's rules and by providing additional guidance relating to the
application of CFE's rule provisions with respect to disruptive trading
practices, the proposed changes to P&P XVIII contribute to the
protection of CFE's market and market participants from abusive
practices; to the promotion of fair and equitable trading on CFE's
market; and to precluding activity on CFE's market that is disruptive
to the operation of the Exchange or the ability of other market
participants to trade, engage in price discovery, or manage risk.
    Accordingly, the Exchange believes that the proposed rule change
will benefit market participants because it will provide greater
clarity regarding the Exchange's current prohibited disruptive trading
practices and the various factors that CFE may consider in assessing
whether conduct violates Rule 620. Additionally, the Exchange believes
that the proposed rule change will strengthen its ability to carry out
its responsibilities as a self-regulatory organization by providing
further guidance regarding the type of activity that is prohibited
under CFE Rule 620. In addition, the proposed rule change benefits
market participants by contributing to the protection of CFE's market
and market participants from abusive practices and to the promotion of
a fair and orderly market.
    The Exchange also believes that the proposed rule change is
equitable and not unfairly discriminatory in that the rule amendments
included in the proposed rule change would apply equally to all market
participants.

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

    CFE does not believe that the proposed rule changes will impose any
burden on competition not necessary or appropriate in furtherance of
the purposes of the Act. Specifically, the Exchange believes that the
proposed rule change will not burden intra-market competition because
the clarifying updates to the prohibited disruptive trading practices
will apply equally to all market participants. The Exchange also
believes that these clarifying updates will help to foster a fair and
orderly market and contribute to furthering the promotion of fair and

equitable trading on the Exchange. Additionally, the proposed rule
change is designed to make CFE's disruptive trading practice rules
consistent with the existing rules and guidance published by other DCMs
and thus will not burden intermarket competition.

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

    No written comments were solicited or received with respect to the
proposed rule change.

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

    The proposed rule change will become operative on October 20, 2021.
At any time within 60 days of the date of effectiveness of the proposed
rule change, the Commission, after consultation with the CFTC, may
summarily abrogate the proposed rule change and require that the
proposed rule change be refiled in accordance with the provisions of
Section 19(b)(1) of the Act.\9\
