@qtip: As far as I can see both companies offer their own interfaces for the order execution while they don't support FIX... (at least not directly).
Thanks anyway.
I'm looking for a broker offering FIX protocol support on the execution side but I'd prefer not to be bound to a certain API for the execution.
Additionally I'll need real-time (tick-by-tick) FX data.
Can anybody recommend a broker providing these services to non-institutional clients...
