Eurex introduced on 29 March 2021 the FIX LF interface. The initial launch of the FIX LF interface was performed as part of the T7 Release 9.0 software. No changes to the T7 Release 9.0 FIX LF interface implementation of back-office sessions neither in the form of documentation nor XML files are envisaged during the T7 Release 9.1 implementation.
Start of simulation: 17 February 2021
Start of production: 29 March 2021
Items/ Participants Requirements
FIX LF interface
Eurex will now begin to introduce the new FIX LF interface which is backward compatibility. The interface will make use of the FIX 4.4 protocol only. Ultimately, the FIX LF interface will ultimately replace the existing FIX Gateway interface.
Existing applications must be adapted to use the new FIX LF interface at the earliest possible opportunity. Members using FIX version 4.2 must also ensure that their applications are adapted to FIX version 4.4.
FIX LF sessions
The new FIX LF sessions will make use of the FIX 4.4 protocol only and be integrated closer into the T7 architecture by providing similar underlying infrastructure and functional/technical characteristics as the existing ETI interface, e.g., backward compatibility.
Members with back-office sessions via the existing Eurex FIX Gateway interface should be aware that support for these sessions will no longer be provided with T7 Release 10.0.
