Deutsche Börse Group will launch Release 10.1 of the T7 trading system on 27 June 2022. Please refer to the dedicated document “T7 Release 10.1 Final Release Notes” for a full overview of both the new and changed functional scope. The document is available on the dedicated initiative page via the link:

Support > Initiatives & Releases > T7 Release 10.1 > Overview and Functionality

A.  Backward compatibility

T7 Release 10.1 will provide backwards compatibility for the T7 ETI/FIX LF interface version 10.0, i.e. participants who do not want to use the new functionality will still be able to connect to T7 with the interface layout version 10.0, even after the production launch of T7 Release 10.1.

Public market and reference data interfaces, including EOBI, EMDI, MDI, RDI/RDF, as well as reports and data files, will not provide backwards compatibility.

B.  Preparations for Friday, 24 June and Saturday, 25 June 2022

On Friday, 24 June 2022, T7 Release 10.0 will be in production for the last time. Reports for the business day 24 June 2022 can be expected at the usual time. On Saturday, 25 June 2022, Deutsche Börse will convert the T7 production system to Release 10.1 and initial reference data for business day 27 June 2022 will be available via RDI and RDF following the start of the system in preparation for the support window. 

C.  Support window for T7 Release 10.1 on Saturday, 25 June 2022

The T7 Release 10.1 support window will be conducted on Saturday, 25 June 2022, between 15:00 and 17:00 CEST. Connectivity testing during the support window is strongly recommended for all participants and Multi-Member Providers to ensure connectivity for the start of trading on Monday, 27 June 2022. Please make sure that a staff member will be available to perform the login to the T7 production system (e.g. T7 Trader and/or Admin GUI and third-party applications).

At this time, the T7 production system will be available for connectivity testing on the ETI, FIX LF, RDI, EMDI and EOBI interfaces and via T7 Admin-, T7 Clearer- and T7 Trader GUI. No order and quote entries will be possible. Technical heartbeats via the market data interfaces will be disseminated.

The support window can be regarded as successful when

• a message “Connection Test Eurex <hh:mm:ss>” appears with an increasing sequence number in the market news view (news board) of the T7 Trader GUI and the T7 Admin GUI;
• either a successful session logon (and optionally a trader logon) via the ETI or FIX LF interface has been performed;
• technical heartbeats have been received on EMDI/EOBI/MDI/RDI addresses;
• functional heartbeats have been received on EMDI/EOBI/RDI addresses.

Deutsche Börse will inform participants about the general progress of the support window via implementation news on the Eurex website available under the link:

Support > Information Channels > Implementation News

Following the end of the support window, the T7 10.1 production system will be shut down on 25 June 2022 at 18:00 CEST and will be unavailable until Sunday evening, 26 June 2022.

D.  Monday, 27 June 2022 – Production start

The first trading day with T7 Release 10.1 will start as usual. 

Please note: As the system will be re-started Sunday evening, after the connection test on Saturday, the initial reference data file for the business day 27 June 2022 will be re-generated. As the reference data provided on 25 June 2022 via RDI and RDF prior to the support window may potentially contain some changes, participants are required to use the initial reference data provided following the system start for 27 June 2022.

Orders entered until 24 June 2022 (end of trading) but not executed, will continue to be available on 27 June 2022, unless other validity restrictions were set.

A list of any items that are relevant prior to the production start of T7 Release 10.1 will be provided as of 24 June 2022. This “known limitations” list will be available on the dedicated initiative page under the link:
