TT® FIX

Operational Notes

FIX services are available 24/7 except during software deployments, which occur Friday evenings approximately every two weeks for UAT environments and monthly for Production environments. Also, TT resets all FIX sessions on Saturdays at 22:00 UTC.

By default, message sequence numbers for FIX sessions are reset when TT resets all FIX sessions. Message sequence numbers can also be reset, when desired, by setting Tag 34 (MsgSeqNum) = 1 and Tag 141 (ResetSeqNumFlag) = Y when sending a Logon (A) message.
