I bought the book because of its title "disciplined Trader", as everyone knows discipline is key in trading, unfortunately this book teaches you nothing about discipline, why it is important or how to achieve it. It has a very complex writing style, talks a lot about pychology (which is also very important in my opinion), but gives no clear picture of what is important or even what the author wants to say. A useless book. A lot of the positive reviews about the book seem planted to me. I am a proffessional trader and cannot see how anyone can benefit from this book.
