One Chicago LLC, a designated contract market authorized by the Commodity Futures Trading Commission, proposed amending its rule prohibiting disruptive trading practices to give greater clarity to members regarding prohibited conduct. Currently, the relevant One Chicago’s rule tracks the CFTC prohibition (click here to access 7 U.S.C. § 6c(a)(5)). Among other things, One Chicago proposed to eliminate its prohibition against spoofing by name, but instead prohibit generally the entering or causing to enter an order with the intent, at the time the order is placed, to cancel the order before execution or to modify the order to avoid execution. Absent objection, One Chicago’s amended rule will become effective August 15. (Click here for background on One Chicago.)
