First of all, I have to mention that this book is not for beginner. It involves a lot of technical terms and techniques that an amateur would not understand. This is probably due to the length of this book because it is so short and full of graphs, it doesn't have enough room to do much explanation and gave examples. Other than that, this is one of the better books that explains rarely discuss TA methods (Bollinger Bands, stochastic, MACD).
I managed to finish reading the book in one day which is fast for such a subject. I was very confused at the beginning 4 chapters because the author used a lot of jargons. It gets better at the later chapters when I got used to some of them and finally understand what they mean. Also, the author mentioned a lot about using some software to produce the charts but he failed to recommend one of them to the readers (actually he did but it's in french). So I have to find one on my own which is not easy but unless you have one that works similar to his, you cannot really apply what you've learned from the book.
Otherwise, the book explained Bollinger Bands, Stochastic, and MACD well. I only wish that the author can give more examples and provide more charts and resources for the readers. It would be best if the book is twice of it original length. I would recommend it if you don't mind the high price tag and have some knowledge of trading.
