I downloaded the Quickfix from https://github.com/quickfix/quickfix. Under the C++/fix50sp2(and other directories), I cannot find the file for TradeMatchReport(DC). Does anyone have any idea on this?
I think your best bet is https://sourceforge.net/projects/quickfix/lists/quickfix-users
Thanks Christoph. (I also checked the value of PartyRole in the source code of Quickfix, it is also a little bit outdated)
