Sequence Numbers

Sequence numbers, both inbound and outbound, will be reset to one daily between 4:00 p.m. CT and 4:45 p.m. CT. Existing FIX connections will be forcibly disconnected at that time each day.

Messages are processed in sequence order. Behind sequence messages (other than Sequence Reset) cause immediate logout. Ahead of sequence messages (other than a Resend Request) trigger a message recovery via a Resend Request.
