I think we should make an opensource trade lib as a reference implementation.
I just wanted to ask one question to all people here thinking about the exchange API standarization:
Why don't use an existing standard like eg. FIX protocol?
http://en.wikipedia.org/wiki/Financial_Information_eXchangeTheoretically it alrady has everything that's required.
So what are the roadblocks? Are they technical or ideological? Maybe a software architecture mismatch? Is FIX simply too difficult? Or is FIX considered tainted for some reason?
Thanks in advance for any light you may shine on this question.
