Several other exchanges in Europe and around the world also use Deutsche Börse's leading trading architecture. In addition to the global derivatives exchange Eurex, the Frankfurt Stock Exchange with its Xetra platform and the European Energy Exchange (EEX), the number one in global power trading, all of which use T7, the cash market trading of the Vienna Stock Exchange also runs on Deutsche Börse's technology. The exchanges in Budapest, Ljubljana, Prague, and Zagreb have also been using Deutsche Börse technology for many years. T7 stands for low latency, enormous reliability, and a high degree of flexibility. This is demonstrated by its diverse use in cash, derivatives, and energy markets worldwide.
