Sorry, this might be a stupid question but what did you mean by that highlighted statement. What are STIRs?
I only trade outright so I am a bit clueless in this regard.
Between the splits and the desk costs it must be very difficult to make money, if these guys were such good traders why would they bother with the hassle of training up loads of guys etc.?
By the sound of then if you have money you would be better to put it in a ftse tracker and get a real job! If the successful traders resort to teaching to make more money that says it all really!
