CME Group proposed minor changes to its advisory regarding its prohibition against disruptive trading practices to clarify that it is prohibited to enter a trading at settlement or trading at marker order into Globex prior to receiving notice that the market has transition to pre-open status. CME Group has also clarified that entry of a bona fide order into Globex that is intended to be executed is authorized even where an execution might serve some other risk management purpose, such as testing the flow of a trade through a firm’s back office system. The changes will be effective October 26, 2015, absent objection by the Commodity Futures Trading Commission. (Click here to access CME Group’s prohibition against disruptive practices – Rule 575.)
