EP300 EU Consolidated Tape for Bonds and Equities
This Extension Pack covers extensions needed to support the EU’s consolidated tape (CT) for bonds and equities defined by ESMA and published by the European Commission2 on June 12, 2025 as RTS document, defining the detailed CT requirements for regulatory and core market data in Annex II and Annex III.
Note that two FIX Recommended Practice documents and one Orchestra XML file (attached as separate file to each of the document downloads) have been published alongside EP300 to provide an official specification for the usage of the FIX Protocol for the EU Consolidated Tape. The Orchestra XML file is the machine-readable version of the message tables provided in the PDF documents. It uses Orchestra scenarios to distinguish between bonds and equities as well as between input data to and output data from the CT provider.

Improvements
Together with EP300, the following changes were also made to FIX Latest:
- Corrected presence of field LastUpdateTime(779) in the message MarketDataSnapshotFullRefresh from required to optional.
- Change the definition of TrdRegTimestampType(770)=34 to be more generic, i.e. not limited to national BBOs.
