I just finished this book. If you have never read the basics of creating a trading system, then this book will be useful as a primer. If you need more detailed information beyond concepts check out Trade your way to financial freedom By Van Tharp.
The book was written in a easy to read and straight forward manner, which I enjoyed and made for much easier reading than most trading books.
The author also includes the original Turtle rules and money management rules as well as several trend following systems as examples.
