OK. I see the point. Basically let say I have an execution system (over FIX protocol) and want to have just Front-End, which will be connected to the system. The idea was to take any available FrontEnd which communicates through published API and write "converter from that API to FIX".
NinjaTrader uses TradeMagic's connectivity to existing execution system, where I basically want to cut.
Anything on that side?
Thanks.
