Queuing Period

The pre-market queuing period for GTH eligible products begins at 8pm ET and the queuing period for RTH only products begins at 7:30am ET.

Complex instruments can also be halted intraday whenever the underlying product for a component leg is halted. Complex orders sent while a complex instrument is halted will also be queued up for a Re-Opening Auction.

During Queuing Periods, the Exchange disseminates expected opening price and size information using Options Auction Update messages over the U.S. Options Complex Multicast PITCH feed once every five seconds during the queuing period.
