Improvements

FIX Services

Made a change in FIX Order Router so that when “Set Security ID Source (22) on Outbound Messages” is set to “Default - Client provided source”, FIX OR will now return the same SecurityID & SecurityIDSource on outbound messages as was provided on the inbound new order (D/AB) messages.

Improvements

FIX Services

For customers whose FIX engine natively supports SSL encryption, or who have implemented FIX session encryption using STunnel with certificate pinning, TT provides a TTFIX.crt file with the public certificates used by the TT platform FIX endpoint. These certificates expire on an annual basis and must periodically be refreshed to continue functioning.

On April 26, 2024, TT updated the stunnel.zip file located in the Download Center in order to update the soon-to-be-expired certs in the TTFIX.crt bundle.

All TT customers who use STunnel must download the new zip file and apply it at any time before the new zip file update is applied in each TT environment, which will be:
>> May 1, 2024 for UAT
>> May 10, 2024 for SIM
>> May 17, 2024 for Production - New York
>> May 31, 2024 for Production - All other locations

Customers still using the old stunnel.zip file after the dates listed above will not be able to connect to the respective TT environments.

Added TT Platform STAR.TRADE.TT; valid from 2024/04/01- 2025/03/31 (DC)
