Market Data Feed

The Market Data Feed from SIX Financial Information is a high performance, normalized real-time feed that provides consolidated data in one single consistent format, regardless of where in the world the data originates. We source data from approximately 1,500 global exchanges and contributors, and work tirelessly to ensure a broad coverage of global markets, which we compliment with derived and calculated figures. You can customize your service level using our logical feed feature, and you can optimize your connection through a choice of API formats.


MDFstream is optimized for high data volume. Based on a sophisticated, rapid queuing system, it has been developed for customers who require a broadcast data feed to service existing cache-based real-time services such as terminal servers, algorithmic trading applications or data distribution platforms. MDFstream supplies real-time and delayed prices, calculated and derived values as well as business news. Dedicated servers are hosted by SIX Financial Information, and can be accessed via the web or via leased lines. The system is scalable to meet your data coverage needs. Delivery is in streaming mode, based on your selection of financial instruments which also defines the necessary bandwidth.


MDFselect is particularly well suited for feeding applications which demand mid to high range data throughput, covering real-time and delayed pricing information, intraday and historical time series, lists and tables, and business news. With intelligent and easy-to-use search functionalities, you can navigate quickly and efficiently through this wealth of information. Data is delivered as streaming updates just like MDFstream but, in addition, enables you to run snapshot queries against data at the stock exchange, instrument or attribute level. Queries can be made using the exchange code and/or the listing identification, e.g. ISIN, NSIN. SIX hosts the MDFselect servers, which can either be dedicated or shared by several clients for a lower cost option for smaller deployments.
