On July 15, the Commodity Futures Trading Commission published a request for public comment on a Market Regulation Advisory Notice related to wash trades that was proposed on July 9 by the Chicago Mercantile Exchange, Chicago Board of Trade, New York Mercantile Exchange, Commodity Exchange, Inc. and Kansas City Board of Trade. The proposed advisory notice would: (i) define wash trade; (ii) define same beneficial ownership and common beneficial ownership; (iii) clarify that unintentional self-trades that occur on more than an incidental basis may be deemed to be wash trades; and (iv) clarify that orders generated in good faith by independent traders or independent algorithms that unintentionally and coincidentally match will not be deemed wash trades. Comments should be submitted to the CFTC on or before August 14, 2013. 

The proposed advisory notice is available here.
