SIX has launched a new data marketplace today that will make data more accessible and affordable through an API-based solution for both institutional and retail traders. The service, SIX Market Signal, publishes real-time and historical data. For institutions, it enables access to market data across a wider variety of users while for the retail clients, it provides first-of-its-kind direct access to real-time exchange data.





The key offering of SIX Market Signal is 1BBO, a European market data stream that will provide real-time coverage of cash equity securities. It will display best bid and ask prices and utilize data from the orderbooks of SIX Swiss Exchange and BME Exchange in Switzerland and Spain and will also include the 16 European markets covered by Aquis Exchange. Only direct data feeds, used by market makers and execution desks, will have faster access to prices. 1BBO will be complimented by historical and intraday data products, with more datasets expected to be added to the SIX Market Signal marketplace over time.

SIX Market Signal allows firms to expand access to market data beyond the execution desk to other functions such as wealth management, benchmarking, and compliance. It serves as an alternative for businesses that can benefit from real-time price streaming.

For retail traders, SIX Market Signal provides access to high‑quality exchange data that balances cost and speed for everyday investor use cases. Through 1BBO, SIX aims to level the playing field for retail investors.
