SWXess: Throughput, Speed and Reliability

Co-location: The Fastest Connection

Co-location services of the Swiss Stock Exchange offer participants many advantages: faster execution, trading irrespective of distance, customizable infrastructure and choice of preferred supplier, cost efficiency and fast on-boarding. A co-location access reduces latency for equity trading to just 14 microseconds. We offer co-location services in partnership with Equinix. By installing their technical equipment in the Equinix data center in Zurich next to the SWXess trading engine, all participants can enjoy the same superior latency regardless of their geographical location.

The Largest Microwave Network in Europe

Microwave technology allows the fastest transmission of trade data. The Swiss Stock Exchange is the first regulated exchange to own and operate an international ultra-low latency microwave network in Europe. Our microwave network enables trading participants – such as market makers and liquidity providers in the equities and ETF space – to execute their trading strategies faster while at the same time improving their risk management. As a result, improved liquidity and tighter spreads create better execution conditions for all market participants.

Access Point Service

The Access Point service is one of the available SCAP options with several Points of Presence (PoPs) in London and Frankfurt. The service has direct connectivity to SWXess with low and reliable latency to both trading environments (member test and production). The Access Point service belongs to existing financial ecosystems and provisions participants with diversity, operational cost optimization and potential leveraging economies of scale.
