Version: v43

03/08/2019

Improvements

FIX Services

Tag 57, TargetSubID, is an optional tag that may be included by FIX Clients in the Logon (35=A) message header.

Beginning with this FIX release, if and only if the Logon message coming from the FIX client to TT contains tag 57, the client admin *must* configure the tag 57 value in the Target Sub ID field for that specific FIX Session configuration dialog in setup.

if the Logon message coming from the FIX client to TT does *not* contain tag 57, no action is required.

This change is applicable to all TT FIX Session Types in Setup.

Version: v43

03/08/2019

Improvements

FIX Services

Added LastMkt (tag 30) to replace tag 100 on FIX 4.4 TradeCaptureReports. No change in behavior for FIX 4.2.

NOTE: tag 30 has been added to the TT XML schema, but will only be sent on FIX 4.4 sessions.
