September also saw the launch of SIX Market Signal. The new data marketplace improves access to real-time exchange data from SIX Swiss Exchange, BME Exchange and Aquis Exchange for both institutional and retail traders.
Gregor Braun, Head Cash Market Sales, Exchanges, SIX, commented: “As markets have moved out of the quieter summer period, it’s positive to see cross-market turnover growth on both SIX Swiss Exchange and BME Exchange. The launch of SIX Market Signal underscores another key milestone in removing accessibility and affordability barriers to high-quality exchange data in Europe. In the long term, this will help increase trading both across SIX markets and European markets as a whole.”
