Its definitely a good starter book for trading futures and Forex. When I picked up the book, I really didn't know what a futures contract was. I studied the strategies, but most of them were not for me as far as my main strategies go. I've used "box plays", but usually within another strategy of my own. The book also introduced me to Market Profile, which has been a huge addition to my trading career. That led me to
Mind Over Markets and somehow I found this site when researching Market Profile.
Carter's book is a great book for a novice, but its only a starting point.
