EEX Kundeninformation – T7 release 12.1 – Final Release Notes

    Dear trading participant,

    EEX will update its Derivatives Trading System T7 to version 12.1 on 13 May 2024, in line with the Eurex Exchanges’ release cycle. In the framework of the release, interface changes will take place and technical enhancements are introduced which will be described in more detail in the Eurex system documentation.

    EEX will ensure the compatibility of the supported trading front-ends Trayport Joule© and EEX TT Screen.

    Important dates:

    • Simulation Start: 25 March 2024
    • Production Start: 13 May 2024

    1. Notes on Interfaces
    T7 Release 12.1 will provide backwards compatibility for the T7 ETI / FIX interface version 12.0, i.e., participants who do not want to use the new functionality will still be able to connect to T7 with the interface layout version 12.0, even after the production launch of T7 Release 12.1. Public market and reference data interfaces, including EOBI, EMDI, MDI, RDI/RDF, as well as
    reports and data files, will not provide backwards compatibility.

    2. New fields in RDI / RDF
    With T7 Release 12.1, the instrument snapshot of RDI / RDF will be enhanced by two new fields:

    • SecRefDataSupplmnt – tag 2962
      This field will be set identical to the field ContractDate – tag 30866
    • MaturityFrequencyUnit – tag 2982
      This field will be set identical to the field ContractFrequency – tag 30867

    The newly introduced fields SecurityReferenceDataSupplement and MaturityFrequencyUnit are FIX compliant fields supported by the latest FIX Protocol. Both newly introduced fields will exist in parallel to the already existing fields Contract Date and Contract Frequency.

    Additionally, the following fields will be added to RDI and to RDF in the Product snapshot by the exchange:

    • Maximum Order Value by Exchange
    • Maximum Order Quantity by Exchange
    • Maximum Calendar Spread Quantity by Exchange
    • Maximum TES Quantity by Exchange

    Please do not hesitate to contact us if you should have questions.

    Yours sincerely,
