SWXess

SWXess is modular, consisting of four basic business service components, each with a separate interface. Participants only subscribe to the business services they need for their activities. The business service components are the same for both markets, SIX Swiss Exchange and Scoach. The following gives a brief description of the business service provided by each interface.

• The Market Data Interface (MDI) is required to receive market data in real time.
• The Reference Data Interface (RDI) is required to access security-related and participant-related reference data, made available for download in the SIX Swiss Exchange Member Section.

To access the business services of their choice, participants need to establish a connection to the appropriate interfaces via the "SIX Swiss Exchange Common Access Portal" (SCAP).
