About This Service

Our aim is to provide low-latency, high-quality data conveniently and efficiently, regardless of location. We do this through two core services: SIX MDDX Multi-Dimensional Data fluX® (SIX MDDX) and ITCH Market Data Interface (IMI).

SIX MDDX provides vendors with real-time market data from the SWXess Trading Platform (including MiFID/MiFIR data content such as UTC timestamps with microsecond granularity as well as MMT trade flags), SIX index data, Swiss Fund Data, reference data from CONNEXOR and other sources, Bespoke data sets (based on Regulatory Technical Standard requirements, using the SoupBinTCP point-to-point network protocol) and third-party content.

SIX MDDX will be used to distribute real-time market data from ARTEX, an innovative MTF for art shares aiming to democratise investment opportunities in timeless assets. SIX will also provide Clearing and Settlement services to ARTEX via SIX x-clear AG. Discover more about ARTEX

Get access to market data as quickly as possible: IMI connects participants with both the SWXess Equities and Non-Equities On Book Matcher (OBM) Partitions. For the Equities OBM Partition the interface is enhanced to provide the highest speed possible – participants and traders can benefit from the renowned high-performance industry standard of the ITCH protocol.

Historical Price Service (HPS) delivers daily all tick-by-tick data per partition (equity and non-equity). Distributed via a web based download, the service is available to all interested customers.

The download files contain all order book updates for the entire business day.

They are an exact copy of the ITCH Market Data Interface (IMI) payload (see section 6.6.1 in the ITCH Market Data Interface (IMI) Specification).
The HPS  service provides the accumulated files of the current month plus the history of the last 11 months on a rolling basis.

If you want to  test the feasibility of your project with HPS and understand how much work is needed for decoding the HPS file, you can request a free trial and  we will provide you with a package of 3 files containing:

  • ITCH Market Data Interface (IMI) Specification
  • Static Binary Capture of 1 trading day on Equity Partition
  • Text decoded version of the same binary capture above

Please  liaise with SIX Exfeed Customer Support ( for more details.

Individual data queries on investment products made easy. The dataAPI service offers, among other data import options, the possibility to download reference data as well as key figures (Greeks, Yield Figures etc.) for individual ISINs in a simple and straightforward way.

The data source for this is CONNEXOR IBT & IBE, which provides the relevant data based on "Issuer Approved Data" for the dataAPI service.
