Actually don't piss this thread off yet guys...
I've never done Bill's courses but have read his book 'Trading Chaos' and traded Forex with his system on MT4. I actually have found it of a lot of interest and more profitable than anything else I've come across or been able to develop, to trade FX that is. But I haven't traded it long enough to really convince myself that it works, over the long term.
Bill says in his book that if you ever doubt his system works, pay him a visit in his trading room. Next time I'm in the US, I will do that. Would certainly like to see his method work as well as he describes it in his book.
