Good Morning

I’m working on a project around commission sharing agreements (csa) with particular reference to shipping the details out on a FIX message (NOS/NOL rather than notification).

I’ve looked through the spec’s and this website for suggestions about what the industry standard may be, a discussion on the 4.2 Changes forum ([http://www.fixprotocol.org/discuss/read/88a1c445](http://www.fixprotocol.org/discuss/read/88a1c445)) suggests that the best use would be to use the regular commission tags (12,13) along with ProcessCode (81) to signify a CSA.

I can certainly see the logic of this but I would be extremely interested to hear from any other sites who have a solution in production, particularly if both execution and research commission details are being sent.

Thanks in advance for your help

Jim
