4. Preparations for Friday, 15 November and Saturday, 16 November 2019

On Friday, 15 November 2019, T7 Release 7.1 will be in production for the last time. Reports for the business day 15 November 2019 can be expected at the usual time. On Saturday, 16 November 2019, Deutsche Börse will convert the T7 and T7/FX production systems to Release 8.0 and initial reference data for business day 18 November 2019 will be available via RDI and RDF following the start of the system in preparation for the support window.

5. Support window for T7 Release 8.0 on Saturday, 16 November 2019

The T7 Release 8.0 support window will be conducted on Saturday, 16 November 2019, between 15:00 and 17:00 CET. Participation during the support window is strongly recommended for all participants and multi-member providers to ensure connectivity for the start of trading on Monday, 18 November 2019. 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 Eurex T7 and T7/FX production system will be available for connectivity testing on the RDI, ETI, MDI, EMDI and EOBI interfaces and via T7 Admin GUI and T7 Trader GUI. The FIX gateways will be available for session login only (no other requests will be possible). No order and quote entries will be possible. 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
  • a successful session or trader login via ETI has been performed.
  • MDI/EMDI/EOBI/RDI heartbeats have been received.

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

Following the end of the support window, the T7 8.0 production system will be shut down on 16 November 2019 at 18:00 CET[1] and will be unavailable until Monday morning, 18 November 2019.

6. Monday, 18 November 2019 – Production start

The first trading day with T7 Release 8.0 will start at 01:15 CET as usual.

Please note: As the system will be re-started before Monday morning, the initial reference data file for the business day 18 November 2019 will be re-generated. As the reference data provided on 16 November 2019 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 18 November 2019.
