My apologies if this has been previously discussed however I was unable to identify a thread for it.

Tag 23 is the IOI ID, uniquely identifying an IOI. The protocol does not support, as a standard, the inclusion of tag 23 on the New Order message, providing a true link and relationship to an IOI and any Orders generated in response to the IOI.

  1. Is anyone aware of any plans to offically include Tag 23 on the order message specification?
  2. Short of using tag 23, I know Bloomberg is including the IOI ID information in tag 58. Is anyone doing anything else to support this?
  3. What negative impact would there be, if any, to including this information in tag 23 on a new order message?

Thanks

NewOrderSingle currently already supports RefOrderID (1080) and RefOrderIDSource (1081). These are intended to reference IDs from orders and quotes but do not include IOIs yet as a source. You could omit 1081 and define 1080 to be IOI IDs only in your Rules of Engagement. An extension of 1081 to include IOIs sounds reasonable too.
A recently approved extension (ISE Order Handling, http://www.fixprotocol.org/documents/5503/FIX%20Protocol%20Gap%20Analysis%20ISE%20Order%20Handling%20Extensions%20v06.doc) will add RefClOrdID as a new tag which is a reference to your own ID.

Jed,
Tag 23 has been included in the order-single message at least as far back as version 4.0. What version are you using?

Hi Jed

As Dean points out, you must have missed IOIid in the order message - because it has always been there. However, it is an easy thing to miss with so many fields.

You might like to try using FIXwiki which helps.

For example, the bottom of the FIXwiki page for IOIid (Welcome fixwiki.org - BlueHost.com) has links to all messages where that field is used. You will see that NewOrderSingle is included.

Then if you click on the NewOrderSingle link you will see on the NewOrderSingle page (Welcome fixwiki.org - BlueHost.com) links to the contents of that message for all FIX versions.

If you click on the link to the earliest version of NewOrderSingle - FIX.2.7-4.0 you will see the content of the message for those earliest versions (Welcome fixwiki.org - BlueHost.com) - which does indeed include IOIid.

Thanks, Dean, for catching that. I had not even checked, assuming it was indeed not available on the NewOrderSingle. The generic solution with RefXXXID fields is hence not needed in this case.

Thanks guys. Clearly I had missed the presence of Tag 23 on the New Order Single message specfication. I appreciate you pointing it out for me. Looking again I do see that it has been included.
