New Order Single for REPO on GC Basket

1

Dear all

I’m checking which is the best way to implement this scenario and I really appreciate any comment on this.

We have to implement, as a venue, the possibility to receive from an OMS a New Order Single for REPO on GC Basket. As soon as the OMS receives the Trade Execution Report related to the order, the GC Basket could not be still defined. The GC Basket definition [ i.e definition of the securities. Each security defined generates a Trade and Settlement Instructions] could occur at a latter stage on Trading Venue ( but on the same trading day and before Market Close) .

Do you think the OMS needs to receive the notification about the GC Basket definition? If yes which is the proper way to notify it via FIX?

Any comment and feedback would be really appreciated. Many thanks.

What exactly is in the GC basket is likely defined already in the Repo agreement between the parties.
