On all days other than the final trading day of the week and the day before a mid-week holiday, these contracts will continue to have a two-minute post-close session using the closing range as a trading range.
Unlike the current post-close session, there will be no restrictions for the end-of-week session on placing and executing new orders. However, only orders entered after regular trading ends may be executed during the end-of-week session.
Also unlike the current session, prices will be disseminated for the end-of-week session, but they will not be factored into the settlement price, just as they aren't currently. The end-of-week session will begin 20 minutes after the close and will be limited to trading in the first four months of the contract. Post-close trading is also currently limited to the first four months.
This rule change has been approved by the Commodity Futures Trading Commission.
Exchange Executive Vice President Neal Wolkoff said, "This session has been requested by both our floor community and customer base as an opportunity to provide a more expansive range in which participants can adjust their positions prior to gaps in market access due to holidays and weekends."
