This is a history of technical analysis. For some reason the author call it evolution as if it were a continuous development. The author does not have any access to primary sources so there is absolutely nothing new in this book. If you want to write the history of something, you need access to primary sources, eg old newsletters, interviews, subscription statistics. When you have access to primary sources you can add something new. I don't think the author know this basic nature of history writing.
So this book is just an uncritical rehash of knowledge that is out there in various books. For instance, we get a few tired pages on candlesticks in Osaka. These could just have come from the introduction in Nison's book. We also get a chapter of the efficient market idea, which is about the opposite of technical analysis. The author probably read a book about it and decided to add a chapter because the book was running a bit short. I don't think the book has anything interesting to say at all.
It is obvious that I don't like the book. Within a couple of days my review had received 8 negative feedbacks. I guess it is just fair. If I trash the book, the friends of the author can trash my review. I suppose I'm hitting a nerve. If this was a good book there would be no need to trash my review. Instead there would already have been several reviews praising the book. Maybe the next step will be positive reviews written by individuals who only have reviewed one book each. There's a challenge :)
Finally, I've read four books published by Bloomberg Press. Two one star and two three stars. Not a very strong track record. So probably a good idea to be careful with that publisher
