Very good question, if you notice, i clearly cited this book as the last book to read after having consumed all the previous material in the other books,this will be the cream on top of the cake, this book will teach you to manage risk as thoroughly as you seek reward, know the importance of news and its effect on the money market,and most importantly it will teach you that nothing can be accuretly predicted,teaching you a valuable lesson about the world of forex and the stock market,it's not about how much you win...it's how much you dont dont lose.
Im quite sure you haven't even skimmed the book let alone read it,as had you had the curiosity to give it a good read, you wouldnt be coming to me with this question
