I read it and didn't find it very useful. Farley says that you have to constantly switch between styles as market conditions change. And not only you have to do that, it's also good to invent new strategies unknown to the crowd. Hm, what happened to the do 1 thing and do it well stuff? In the book he talks about a lot of different stuff. Indicators, Fibonacci, etc. etc. That's kind of pointing toward being jack of all trades and master of none. I found the book too abstract. I guess the most important thing I learned is that he says to fade during ranging environment and to get on breakouts in trending.
