C7 Releases

C7 Release 7.1

With this release, Eurex Clearing migrated settlement prices from the legacy infrastructure into C7. Series generation included in this release is a necessary step in order to achieve this. Please note that the FIXML broker migration to Java has been postponed to the next release in November 2021.

New features, changes and improvements: 

  • Series Generation
  • Corporate Action Processing

Simulation start: 10 May 2021
Production start:  5 July 2021

C7 7.1 timeline (1)


System Documentation

Messaging Interfaces Connectivity



No, Java doesn’t support legacy AMQP version 0.10 and participants need to ensure they upgrade to latest AMQP version 1.0.

"End of stream" message is used to inform about internal broker maintenance. C7 is now decommissioning the "end of stream" message coming from the legacy Eurex Classic as it is outdated. Members should be using the "End of assignment of all products" message which contains the EOD information. There is no difference in processing time for these messages, which are normally sent (if no delays) between 22:35 and 22:45 CET.

No, as all relevant information will be included in new report TA711.

Documentation such as member report, reference manual and modification notes are already available under system documentation above.

Our connection test tool does not provide this feature and we are not planning to do so. Our preferred approach is not to use Client-ID at all.

Connection test tool sources are publicly available here:

If customer feels confident enough, Client-ID can be added to connection string manually in file master/src/main/java/de/deutscheboerse/fixml/ in method public BrokerConnector (final CommonOptions options).

See: jms.clientID in

Yes, it will be validated and if a second FIXML string attempts to connect with the same Client ID, it will receive an error message and won't be able to establish connection.

The field Package ID is already part of the report but is blank in case no basket is traded by the client. 

There are already contracts in simulation with a trading unit cash > 1 such as BMW and ENR (you can see this in the last column "TradingUnitCash" of TA111). For these contracts, TradingUnitShares and TradingUnitCash will change with C7 7.1. It would be a possible test scenario in Simulation, where a CM creates a position in one of these contracts and exercises parts of it before or on 10th of May and the remaining part on or after 11th of May. 

In case of exercises on/before 10 May, the cash settlement will be more than one share (depending on TradingUnitCash shown on TA111) and for exercises on/after 11 May, cash settlement will be only for fractions (depending on TradingUnitCash shown on TA711).

If this test scenario is not sufficient and Clearing Members actually need two subsequent corporate actions (e.g. due to the fact that they have their own logic to calculate TradingUnitShare and TradingUnitCash), we could potentially create this after 11 May with product ENR, please let your Clearing Key Account Manager or know if that's the case.

C7 7.1 readiness statement is required by 25 June 2021.

 Action Items

Series generation

Clearing Business Date @BizDt(715): are be added to contract add/change/delete messages.

Clearing Members and ISVs need to check if their AMQP back office library is compatible with the C7 changes and make the necessary adjustments if required.

Decommission of "end-of-stream" messages

Members are advised to use the "end-of-assignment for all products" message.

Clearing Members and ISVs need to check if their AMQP back office library is compatible with the C7 changes and make the necessary adjustments if required.

Corporate Action Processing

New logic is applied to the physical delivery of options or futures subject to a corporate action:

  • The integer part of the trading unit will always be share-settled
  • The decimal part of the trading unit will always be cash-settled

Clearing Members and ISVs need to check if their AMQP back office library is compatible with the C7 changes and make the necessary adjustments if required.
