Hi All,

Is anyone actively using the MsgTypeGrp component block in a logon message?  I'd be very interested to find out more about your use of this, which counterparties you trade and what your use cases are...

Many thanks,

 

John

Eurex T7 ETI interface (FIX application layer over proprietary session layer, encoding is basically FIX SBE) is providing such information out of band as XSD/XML file which includes much more than just a list of valid message types (see http://www.eurexchange.com/exchange-en/technology/t7/801742/?frag=801744).

  • Message choreopgraphy, i.e. named message flows with node having conditions to express sub-cases
  • Multiple use cases for each FIX message type, e.g. 10 different FIX ExecutionReport message layouts
  • Valid fields and valid values for each field for a given use case of a standard FIX message type
