I actually had this coded up. I've done this many times, either coded it myself or paid someone else to do it.
And guess what...?
There was no statistical edge! I was trading on confidence (ie. an approach which looked very real, but wasn't). Everything is well and dandy until you put your technique under the microscope and have an honest look with a backtest. Then when the maths comes in, you're like "what???", and you start to doubt yourself. And when you doubt yourself, you make losing trades with the very same system!! It's the confidence that puts you in tune with the flow of the market, and it's the confidence which makes you the money.
So the moral of the story is - don't worry about edges or special techniques. Real edges do exist, but none of them are particlarly juicy. If they were juicy, hedge funds would be all over them like a rash and trade them into the gorund.
Big Mike is big on the psychological edge. He says all the top traders spend their time honing that part of their game. I agree with him. In fact I'd say it's 95% of the game.
