Choose Pre-Market Session to place an option order in the pre-market. These orders will be eligible for execution from 7:00 a.m. ET until 9:15 a.m. ET and may only be routed to the CBOE.
Eligible Time-in Force (TIF) for pre-market option trades are Good 'til 9:15, Fill or Kill, and Immediate or Cancel.
Choose Standard Session if you'd like to place an option order for the standard session prior to market open.
