The trading as well as downstream systems are provided by the partner Vienna Stock Exchange:
Trading System Xetra®
Since November 1999, the securities trading system Xetra® has been run in partnership and in close cooperation with Deutsche Börse AG. On average, more than two million transactions per day are securely and efficiently processed. Xetra® forms the technological base for organized securities trading at the Vienna Stock Exchange that operates the system for the Prague Stock Exchange based on Software as a Service (SaaS)-agreements.
Downstream systems cover those areas and processes, which follow after trading.
