7 U.S.C. § 6j — Restrictions on dual trading in security futures products on designated contract markets and registered derivatives transaction execution facilities

(a) Issuance of regulations The Commission must write regulations banning the privilege of "dual trading" (defined below) in security futures products, on every contract market and registered derivatives transaction execution facility. These regulations: (1) take effect as soon as they're issued; and (2) must include exceptions the Commission thinks are fair, such as — (A) spread transactions and fixing trading errors; (B) letting a customer name, in writing, once a year, a specific floor broker to handle their orders even though dual trading is otherwise banned; and (C) other measures designed to fit a particular exchange's unique features, handle emergencies or unusual market conditions, or otherwise serve the public interest — while still promoting efficient, innovative, and expanding markets, protecting investors, and supporting this section's goals. (b) "Dual trading" defined "Dual trading" means a floor broker executes a customer's order during the same trading session in which that floor broker also trades — in the same contract market or facility — for: (1) their own account; (2) an account they have trading discretion over; or (3) an account controlled by someone they're connected to through a broker association. (c) "Broker association" defined A "broker association" is two or more members of a contract market or derivatives transaction execution facility with floor trading privileges — at least one of whom is a floor broker — who: (1) do floor brokerage work for the same employer; (2) have an employer-employee relationship tied to floor brokerage; (3) share profits and losses from their brokerage or trading; or (4) regularly share a deck of orders.
