PUBLIC COMMENT PERIOD - FIX Recommended Practices - MiFIR Transparency

The Global Technical Committee has reviewed and preliminarily approved the submitted proposal. This document from the FIX Trading Community’s Equities and Fixed Income Consolidated Tape Working Groups covers guidance on using FIX standards (specifically the FIX Protocol and MMT) for transmitting and using post-trade transparency data in European securities. It is based on guidelines produced by the FIX Trading Community’s MiFID Transparency subgroup, last updated in May 2017 with new material covering regulatory changes in the EU and UK and greater detail on FIX Protocol field usage.

Please post feedback, comments, and questions as replies to this discussion thread. The public comment period ends on December 8, 2023.
