I haven't red it yet. But amazon reviews look nice:
"This book is among the best you will find on trading. It is based on pure technical charting, no fundamentals here. The author shows how to draw correct channel lines on charts of any time frame. The principles of the book is to make trading decisions based on the inside and outside channel lines. In an up trending market you buy on pull backs to the lower channel line and sell when the stock/commodity breaks the upper channel line. In down trending markets you short the stock/commodity when it is at the upper channel line and cover the short when it breaks the lower line. This is the best way to trade 90% of the time, it works!
