Without revealing his method, I have a couple of his booklets which I bought out of curiosity. Now, what is not addressed which I feel is very important is the percent "drawdowns". If you are trading, you will have drawdowns and even a stock in a long term uptrend could have deep pullbacks resulting on huge losses, depending on when you entered the trade. On paper, it sounds too easy. As saying goes, "if it sounds too good to be true, it probably is." If you trade his system, you probably, will be holding thru the declines too.
On the plus side, it gets you thinking and creating your own trend following system which probably, will be better than what he is offering.
