SIX has launched SIX Market Signal, a new market data service offering affordable, real-time access to European equity prices across 18 markets. The offering aims to democratize access to exchange data for retail investors, fintechs, and institutional participants while reducing the cost barriers typically associated with professional market data feeds.
- Core Product: 1BBO (one best bid and offer) providing real-time cash equity coverage
- Market Coverage: SIX Swiss Exchange, BME Exchange in Spain, and 16 European markets via Aquis Exchange
- Data Licensing: Full rights to use data for training trading models and AI agents
- Availability: Institutional access now live; Swiss retail subscriptions immediate, with EU and UK expansion planned
The service combines best bid and ask pricing from participating exchanges with historical and intraday datasets. SIX Market Signal leverages viaNexus technology for real-time distribution, cloud API delivery, and integration with quantitative and AI workflows. The platform targets users seeking faster access than traditional vendor feeds but at lower cost than direct exchange connections available only to market makers and execution desks.
SIX Market Signal extends beyond trading desks, enabling wealth management, benchmarking, and compliance functions to access exchange data. Users receive full licensing permissions to incorporate the data into retail and institutional use cases without restrictive terms. The service removes licensing friction typically encountered with premium market data subscriptions, allowing broader adoption across different market participant categories.
With Market Signal, SIX is removing the barriers when accessing high-quality exchange data across European capital markets. By leveraging our European footprint, we enable a broader set of market participants to gain timely, reliable price insights that support informed decisions.
