1. Introduction
To harmonise the distribution of market data for products with the same underlying ISIN, Eurex Exchange will make configuration changes for six Single Stock Options products. For the affected products, Eurex Exchange will either re-assign the partition IDs and/or the multicast addresses for the dissemination of market data via the EMDI and EOBI interfaces.
The affected products will be redistributed to the new partitions and/or multicast addresses from the business day 28 April 2025 onwards.
Participants with HF-sessions (HF-sessions always use the partition-specific gateways) will be directly affected by those configuration changes where the Partition-ID will be reassigned. The product reference data will be modified accordingly to reflect the new partition ID.
2. Required action
Moving products from one partition to another may lead to a scenario where Good Till Cancelled (GTC) and Good Till Date (GTD) orders entered and owned by one HF-session come to reside on two different partitions.
As a HF-session login is always partition-specific (via a partition-specific gateway), the respective owning session needs to login to the new partition to manage orders for products which have been moved. To manage orders for products which have not been moved, the owning session needs to login to the old partition.
