I agree with Misty, a I've read the book a well. His 30 week weighted moving average is a method that can be used for taking profits or making entries - but there is always a great chance the stock will move against you, the same as any other method.
In the perfect world of any trading book, tackling the market looks so simple that it's literally a given that one will make money from reading the matter. Enter the world of reality, where the battle rages between your mind, your funds and the market. Generally, he who holds on to the lowest level wins, at least it was like that before the GFC. And even now, it looks like many who have refrained from selling at or near the bottom have done very well.
Here is my view. Any rally could turn into a long term bull market. Any correction could turn into a long term bear market. It is why people take profits - just in case!
