Hi,
FIX Sell side firm, if never uses tag 41 in any message (cancel done/replace done) is a standard 4.0 practice?

how to keep track of orderids…in multiple replaces case if tag 41 is never used?

thanks.

For ECN like Brut (FIX 4.0), they send tag 11 (ClOrdID) with the OrigClOrdID on the modified or canceled message.
However, this is configurable…it means they could either sent tag 11 with the Cancel/Replace ClOrdID or the OrigClOrdID. On your application, you probably need to do some book keeping and do a lookup for the OrigClOrdID.

Hope that helps.
