Hi Steve,
I never used any predicting tools when trading. I suspect BW hadn't have a whole system when writing his first book and that's why MFI and Bullets appeared in it - it was contradictory to what he wrote in his second one. His original technique from the second book requires a sizeable account - I backtested it and found 500K as a comfortable level. It takes to have a Money-Management and some Equity-Trading Rules when applied to lesser accounts. What I gotta say is BW technique represents just a tool and has to be applied carefully.
