I'm new to FIX protocol development. Our company needs to connect to a broker and they are using FIX5.0/FIXT.1.1
I want to know which specific tag i can add "reference" information in the tag and the FIX server, whatever it does (reject, execution report, acknowledge, whatever) it would resend the tag with the same information.
I am not talking about Tag=11 (ClOrdId) or Tag=41 (OrigClOrdID) I know these return data back to me as well, but i need another tag that does similar. So is there a tag like this, like a reference tag where if I send the text "Hello World", it should send back to me "Hello World" always if it's from the same order.
