FI out of band negotions

Imported from previous forum

Hi,
our trading platform is used for out of band negotiations. We would like to use fix for the back office functions.

I have been through the FI section in volume 7, however it appears that execution reports and trade capture reports are only sent from the market makers. There seems to be other similiar mentions in this discussion forum.

We would like to send the price maker, and the price taker, an appropriate message.

Is anyone sending some sort of a post-trade settlement message to the price maker in FI?

(can you send a pre-agreed order?)

Many thanks in advance.
