24x5 Feed Hours and System Restart (C1 Only)

For C1 Options operating in 24x5 mode, the Auction feed starts on Sunday at approximately 1:00 p.m. ET and shuts down on Friday at approximately 5:30 p.m. ET. A daily restart occurs between 5:30 and 7:00 p.m. ET each day at which time sequences will be reset. The daily restart is typically observed between 5:30 p.m. and 6:00 p.m. ET, but could occur later if needed for operational reasons. Feed startup and shutdown times may be adjusted without notice. Persisted GTC, GTD, and DAY orders are added back into the order book starting at approximately 10 minutes prior to the scheduled queuing time for each underlying symbol.
