Eurex’s T7 Release 15.0 is scheduled for production on 9 November 2026. The exchange’s 23 October circular requires participants to submit readiness statements and named technical contacts by Friday, 30 October. This is an interface migration with compatibility changes, not merely a cosmetic platform update.[1]

The changes cover trading and market-data interfaces, including ETI, FIX LF, EDCI, EOBI, EMDI, MDI, RDI and RDF. Deprecated ETI order requests are removed. The Java Admin GUI is retired in favour of the Web Admin GUI.[1]
Test retained state as well as new connections
A successful connection is only the start of readiness. The important operational test is whether the participant can submit, amend and cancel the messages it actually uses, interpret the resulting responses and reconcile orders that persist across the migration. Reference data also needs to match the new production environment.[1][2]
This creates a coordination task between a broker and its vendors. A supplier may certify its adapter while the broker’s downstream risk or reporting component still expects the old fields. Mapping the dependency chain helps identify that gap before the production weekend.[1][2]
The readiness deadline, connectivity test and launch are separate milestones. Passing one does not substitute for completing the others, and later release features should not be assumed to arrive on the initial production date.[1][2]
