Please note, for PIT traded CME, CBT, Comex, and NYMEX products there is a major change in the way that the modified post-close trading session will be handled. The post-close session is the three minute trading session that occurs at a designated time after the trading day is over. Previously for CME and CBT products there were restrictions over what prices could trade in this session. Today the restrictions will be removed and prices can trade anywhere in the daily price range. New highs and lows can be made in this session as a result of the change. Please view the advisory the CME has issued regarding this change which includes a Q&A section. http://www.cmegroup.com/rulebook/files/CME_Group_RA0906-5.pdf
