Trading is inextricably linked to the speed of data transmission, its accuracy and permanent availability. CEF® real-time data feeds meet these requirements. Four direct feeds – CEF® Core, CEF® ultra+, CEF® DataSelect and CEF alpha® – which vary in terms of data scope, the possibility for data selection, and data format are ideal for meeting your market data access requirements. CEF® data feeds provide market data directly from Deutsche Börse’s trading venues (e.g. Xetra® and Eurex®) and those of its cooperation partners. CEF® Core The complete international portfolio of real-time market data of Deutsche Börse and its cooperation partners, through standardized Information Products that can be used for internal as well as external data dissemination. These Information Products contain, for example, prices and volumes from Xetra®, Eurex®, Eurex Bonds®, Dow Jones STOXX®, the U.S. Futures Exchange and the Irish Stock Exchange. CEF® ultra+ The high-performance and functionally enhanced high-speed real-time data feed offering the entire chain of Eurex® pre-trade and trade information, offering up to order book depth 10 for options and up to 20 for futures. All order book updates are distributed un-netted right when they occur – at a throughput time of less than a millisecond. The applied multicast technology allows individual selection from a current total of 40 product groups, e.g. “Fixed Income Futures”. CEF alpha® Feeds real-time market data from Eurex®, Xetra®, Deutsche Börse and Dow Jones STOXX® Indices directly into automated trading applications. You can select up to 100 single instruments to tailor the data stream exactly to your individual trading strategies. Via CEF alpha®, all data can easily be integrated into existing architecture by using varying formats (e.g. csv, xml and binary CEF® format). CEF® DataSelect Offers the advantage of data selection for up to 3,000 instruments from the complete data portfolio of Market Data & Analytics. Compared to CEF® alpha, data procurement via CEF® DataSelect is not limited to feeding automated trading applications. After concluding a Market Data Dissemination Agreement you can disseminate the market data internally as well as externally.
