EDM/IDM

When trading on-MTF EDM/IDM values must be populated in the outbound quotes and any resultant ExecutionReport messages. For on-MTF requests here is a summary of the various Venue's behaviour:

Current UAT:

• FXall - doesn't use this information, so there are no mappings  and you could do what you wanted without any difference in behaviour.
• CNX_RFS - if you omit or provide erroneous information, you will find that your quotes are simply dropped silently and do not make it through to the client GUI.

FYI for the future: 

• 360T - Even with missing or erroneous information, the quote will be published. However if the client attempts to trade, 360T will reject the request. No message is sent back to the Maker at this stage, so from your perspective it just looks as if every RFS times out.
• Bloomberg - Mandatory for MTF, if you omit or provide erroneous values, the quote request will be terminated. So far, only Bloomberg will actually return a meaningful error, here is an example of what we receive:

  8=FIX.4.4|9=0302|35=b|49=BLP|56=MFMA_RFS|34=7|52=20191002-10:12:00|300=8|301=0|131=BLP.RFQ.800254719_MFTA|117=S1570011120.46998|297=5|58=Failed to convert to GPI, ShortCode=Dmitry_xxx DealCode=MFMA roletype=makerExecId   DEAL_CODE: MFMA FIX_SESSION: MFMA_RFSQuoteReqId=BLP.RFQ.800254719_MFTA quoteId=S1570011120.46998 |10=202|

  (Dmitry_002 was the correct EDM value in this case). We will convert this rejection into a QuoteResponse and forward the error message as-is.

Also, at the risk of me stating the obvious, these details are required on-MTF only  - if OFF, or testing SEF then, again any values you provide will be ignored.
