 Cash commodities or "actuals" refer to the physical goods—e.g., wheat, corn, soybeans, crude oil, gold, silver—that someone is buying/selling/trading as distinguished from derivatives.In a call option counterparties enter into a financial contract option where the buyer purchases the right but not the obligation to buy an agreed quantity of a particular commodity or financial instrument (the underlying) from the seller of the option at a certain time (the expiration date) for a certain price (the strike price).The seller (or "writer") is obligated to sell the commodity or financial instrument should the buyer so decide.
