Pending all relevant CFTC regulatory review periods, effective September 15, 2014, CME, CBOT, NYMEX and COMEX will adopt new Rule 575 (“Disruptive Practices Prohibited”). New Rule 575 and the accompanying Questions & Answers and examples in this Advisory Notice codify particular types of disruptive order entry and trading practices that the CME Group Exchanges find to be abusive to the orderly conduct of trading or the fair execution of transactions. Such practices have historically been prohibited by and prosecuted under other Exchange rules, including, but not limited to, Rules 432.T. (“to engage in dishonorable or uncommercial conduct”), 432.B.2. (“to engage in conduct or proceedings inconsistent with just and equitable principles of trade”), and 432.Q. (“to commit an act which is detrimental to the interest or welfare of the Exchange or to engage in any conduct which tends to impair the dignity or good name of the Exchange”). Other disruptive practices not covered by this Rule 575 may continue to be prosecuted under other Exchange rules including, but not limited to, 432.B.2, 432.Q and 432.T.
