Market Signal

Market Signal is a European, API-based market data marketplace from SIX. Through a single cloud-based connection, users can access ready-to-use real-time and historical exchange data from SIX Swiss Exchange, BME in Spain and Aquis Markets across the UK, EU and Switzerland.

Market Signal is designed for retail investors, developers, fintechs, startups, brokers, banks, quantitative analysts and institutional users. The data can support monitoring, trading models, analytical applications, wealth management, benchmarking, compliance and AI workflows. See the Market Signal launch announcement.

The Market Signal data offering includes real-time indicative top-of-book data covering more than 4,000 equities, official exchange-generated reports with end-of-day summaries and trading statistics, and analytical datasets such as flow and concentration analytics. Historical and intraday products complement the real-time offering.

SIX 1BBO is a consolidated real-time feed providing best bid and offer prices and trade information from SIX Swiss Exchange, BME and Aquis through one API. It covers cash equities across Swiss, EU and UK markets. The feed is indicative and is not the same as the faster direct feeds used by market makers and execution desks.

Market Signal provides one API connection to trusted exchange data across European venues. Cloud delivery eliminates the need for physical exchange connectivity, dedicated servers or co-location. An all-in-one license, no reporting obligation and ready-to-use datasets reduce complexity and can shorten development cycles. See the Market Signal product page.

Market Signal combines cloud-based API delivery with transparent subscription packages, removing the need to establish and maintain traditional physical market-data infrastructure. Plans serve different usage levels, from individuals and developers to startups and institutions. SIX describes this as an affordable European market-data alternative.
