3.   Details 

A. Introduction schedule and Communication Calendar for T7 Release 9.1

Please refer to the Attachment for the introduction schedule and the Communication Calendar. 

The Communication Calendar lists all important dates on which documents for T7 Release 9.1 will be published, including existing documents that will be revised for T7 Release 9.1.

In January 2021, Eurex Exchange will publish the detailed preliminary Release Notes listing the functional and technical enhancements that will be available in T7 Release 9.1.

Deutsche Börse will provide a dedicated release simulation environment in order to give Trading Participants and Independent Software Vendors (ISVs) the opportunity to perform comprehensive testing of their trading applications, independently of the T7 production environment. 

In addition to the T7 release simulation, Trading Participants can also use the T7 Cloud Simulation that allows Trading Participants and 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 to the usual release simulation.

For more information on the T7 Cloud Simulation, please refer to the Eurex website under the following path:

Tech > T7 Cloud Simulation

Eurex Exchange is committed to providing Trading Participants and ISVs with information updates throughout the development of T7 Release 9.1 in order to support adequate planning and to ensure a successful launch.

B. Overview of functional enhancements

The following paragraphs provide an overview of the functional enhancements which will be introduced in T7 Release 9.1.

Extension of the Equity Bespoke Basket Trading Product Scope

Eurex Exchange is planning to expand the scope of type of products available for equity bespoke basket (EBB) trading, which will also include options products as well as additional futures products.

In addition to the product type extension, it will be possible to combine any of these types of products available for EBB Trading within a Basket according to the respective exchange provided bucket definition.

Please note that the Total Return Futures Basket Trading functionality will remain as is.

Eurex EnLight enhancements

The requirement will consider enhancements of the T7 Trader GUI regarding Eurex EnLight.

New contract-specific reference data

In the context of decommissioning the Eurex legacy system, contract generation will be taken over by the T7 trading platform. T7 will therefore be able to publish additional information including new contract-specific reference data, which will be published via the Eurex Reference Data Interface in fields introduced in T7 Release 9.0 already shortly after the launch of the T7 Release 9.1.
