The presence of tag 393 indicates the inclusion of futures allocations in the execution report. The value set to 1 will notify there is no futures allocation and the value set to 2 will notify the fill includes of futures allocations.

Improvements

FIX Services

Admin users now have the option to configure the time zone of the FIX session reset times. The field TimeZone under the FIX Session setup supports for time zone values consistent with the Olson database. This feature will eliminate the task of updating the session reset times every spring and fall.

All reset times currently in setup are unchanged and remain in UTC. Hence, there will be no impact to the ongoing session setups.

After the release, the users can update the time zone and reset times based on user preference.
