A.  T7 Release 8.1 timeline

The launch of T7 Release 8.1 is planned for 29 June 2020 for the trading venues Xetra and Börse Frankfurt.

The simulation is planned to start on 4 May 2020.

Deutsche Börse AG will provide a dedicated simulation environment in order to give Trading Participants the opportunity to perform comprehensive testing of their trading applications, independently of the T7 production. 
The simulation is planned to start on 4 May 2020.

In addition to the T7 release simulation, Trading Participants can also use the T7 Cloud Simulation that allows Trading Participants and Independent Software Vendors (ISVs) to test against the current T7 production and simulation software versions. In this environment, Trading Participants can initiate predefined market scenarios and test specific strategies more easily than in a shared environment. The T7 Cloud simulation is permanently available (24/7) for a fixed price per hour and is accessible using an SSL-encrypted internet connection. The T7 Cloud Simulation will start in advance of the usual release simulation. For more information on the T7 Cloud Simulation, please refer to the Xetra website under the following path:

Please refer to Figure 1 in the Attachment for an overview of the introduction schedule.
