PLEASE NOTE:  As a result of these changes, the multicast addresses and/or partitionID for the affected instruments will also change e.g. Instruments to be included in the SDAX index will receive the same multicast address / partitionID as other instruments in the SDAX index. The reference data containing all the respective changes will be provided following the start of the T7 trading system for the business days Monday, 23. March 2020.

As summary of the partitionID changes is as follows:

In addition to the above mentioned changes, the multicast addresses and partition IDs for some instruments currently assigned to the default group on partition 59 will also be moved to a different partition and receive new multicast addresses. In general, new instruments added to the T7 production system are assigned to a default group on partition 59. This change will ensure that instruments of the same Product or Product Assignment Group (PAG) are located in the same group on the same partition.

For example, affected instruments currently located on partition 59 with the PAG = MDX1 will receive the same multicast address as other instruments with the PAG = MDX1 on the target partition (partition 58). An overview of the multicast address currently assigned to the PAGs on a particular partition can be found in the "All tradable Instruments" file on the Xetra website (www.xetra.com) under the following link:
