The FIX MMT Committees are currently working on delivering the FIX MMT v5.0.

This standard upgrade will cover the regulatory changes applicable to trade flags, as stated in the revised RTS 1, RTS 2 and unnumbered RTS on consolidated tape input/output in the EU.

The final MMT v5.0 data model will be published once the EU Commission has formally validated the ESMA recommendations. This validation is currently expected in May 2025, corresponding application date to be + 9 Months (February 2026) for the 1st batch of changes.

A summary of the expected changes was presented at the FIX EMEA Trading Conference 2025 (March 6) and can be found in the attached power point presentation.
