Eurex Enhanced Trading Interface (Eurex ETI)


The Eurex ETI is the high-performance, low-latency trading interface designed for Participants that require optimal performance and customization. This interface supports full trading functionality, including Market-Making.

Eurex FIX LF Interface


The Eurex FIX LF Interface is designed for Participants who want to utilize the industry standard FIX Protocol.

Eurex Enhanced Market Data Interface (Eurex EMDI)


This interface provides un-netted price level aggregated market data using multicast technology. It also provides un-netted market data. The updates of the order book are delivered for all order book changes up to a given level; all on-exchange trades are reported individually. 

Eurex Enhanced Order Book Interface
(Eurex EOBI)


Though most of the functional concepts are similar to the Eurex EMDI, the EOBI provides several enhancements including but not limited to: side, price, priority timestamp and displayed quantity of each visible order and quote, trade price and traded quantity for each executed on-exchange trade, order book information disseminated without any depth limitation and manually entered trades and trade reversals by Eurex Market Supervision. This interface provides the entire visible order book, by publishing information on each individual order and quote along with state information in un-netted manner. All on-exchange trades are reported individually. See “T7 Enhanced Order Book Interface - Manual ”. 

Eurex Market Data Interface
(Eurex MDI)


This interface provides netted price level aggregated market data using multicast technology.
The updates of the order book are sent at regular intervals; they are not provided for every order book change and are sent significantly less frequently than the T7 EMDI. On-exchange trades are not reported individually, however statistical information (daily high/low price, last trade price and quantity) is provided instead. 

Eurex Reference Data Interface
(Eurex RDI)


This interface provides reference data via high bandwidth connections, including intraday updates. Some reference data (e.g.) for strategies created intraday is also disseminated via Eurex MDI and the incremental channel of Eurex EMDI. It provides reference data for products and instruments that are available for trading on the T7 Exchange’s T7. The reference data is delivered on a product and instrument level. Every tradable object is referenced by a unique identifier, for this reason the reference data information is absolutely essential for any trading application. 

Eurex Extended Market Data Service


The interface provides public off-book trade prices, intraday settlement prices and adjusted open interest. It also allows Participants to replay market information.

Eurex Trader GUI


The "Eurex Trader GUI" provides access to trading functions for orders and Eurex Trade Entry Services. Authorized traders can also trigger an emergency stop trading and other risk controls on this GUI. It is recommended that Participants also operate the Eurex Trader GUI as a backup to alternative front-end systems.

Eurex Admin GUI


The "Eurex Admin GUI" allows authorized users to perform administration functions, e.g. set up new traders, administer user access rights and assign product limits. Authorized administrators can also trigger an emergency stop and other risk controls on this GUI.

Common Report Engine


Trading reports and files, audit trail reports and reference data files are provided exclusively via this service.

  • Trading session: supports order management, request for quote, cross trade announcement, Client Liquidity Improvement Process (CLIP) (Derivatives only), risk control events, strategy creation (Derivatives only) and off-book trade entry (Cash only). Each session will receive information for all of its own orders. Several traders may share a single session, but every session can only be instantiated once. 
  • Back-office session: used for receipt of trade confirmations at business unit level. Clearing business units receive trade confirmations from their trading business units and from their non-clearing members. Back-office sessions can be configured to receive additionally drop copy information for standard (not lean) orders as well as risk control events at the business unit level. The clearing members don’t receive drop copy order information from their non-clearing members

Back-office session supports only a subset of the Regular Trading Low Frequency Sessions. Please refer to the section 5 in Enhanced Trading Interface Manual for the details.

The ETI interface will supports three session types: low frequency sessions for regular trading, low frequency session for back office, and high frequency session. The following table provides an overview on the functionality supported by the different session types:
