Query: so far disappointing

The book is not well written. The author does not clearly explain her thinking, she hops from topic to topic without connecting the ideas behind the topics, and always assumes that the reader has some working knowledge on the matter she is writing about.That is not to say that the book cannot be useful. The author has some good points on why technical analysis can work, but it is a petty that more often than not her message does not come across.
