Query: Explained by the Expert

Many talk about mr. DeMark. I'd found soo many versions of his work that I could not make up anymore what is actually original. Thats why I bought his book. Compared to other books, some simpler explanation is done (but not too simple), which means a little more paper to explain the issues, which I like very much. This brings me into the power to skip the things I already understand and continue on my own level. The material is basic and at the same time advanced. Even for non mathematic fellow traders this book is very well readable. I thank mr DeMark for sharing his knowledge.
