New T7 Web GUIs

New T7 Web GUIs 

Starting 2025, Deutsche Börse is introducing a new generation of T7 Graphical User Interfaces (GUIs) designed to enhance user experience and significantly simplify maintenance. These new GUIs will gradually replace the original T7 GUIs that were launched with the T7 trading system.

Opposed to the original T7 Trader, Admin, and Clearer GUIs that are requiring Java runtime installations, regular updates, and a dedicated launcher, the new T7 Web App GUIs offer a modern, lightweight, and state-of-the-art interface while maintaining the full functionality of Java-based versions.

To access the updated GUIs, users simply need a modern web browser and a compatible client certificate, making operations smoother and more convenient.

All technical documentation for the new T7 WEB GUIs may be found in the usual location under: under: under: Xetra > Technology > T7 trading architecture > System Documentation

New GUIs significantly reduce maintenance by providing a modern, state-of-the-art, lightweight GUI and enhance user experience & simplify maintenance

Client certificates can be effortlessly downloaded & used immediately

Client certificates signed by Deutsche Börse PKI can be downloaded from the Member Section

New Web GUIs will be introduced in a stepwise approach starting with the Clearer GUI (2025), followed by the Admin GUI (2026) and finally the Trader GUI (2027)

Each GUI will be introduced in Simulation, followed by production.  

Previous Java and new Web production GUIs versions will run in parallel for one release cycle. 

Conduct Comprehensive testing in simulation and production.

Become familiar with the new layout prior to Java GUI decommissioning.
