SB trading over FIX

Imported from previous forum

Good day,

How can I specify SB instrument in NewOrderSingle? For example, SB for EUR/USD pair? In my understanding I should specify intrument type through SecurityType (167) or CFICode(461). However, I can’t find appropriate SecurityType/CFICode value.

(This is same question as I asked for CFDs – thanks a lot for your replies).

Thank you
