In all honesty, I am not sure the 7-10 method shows anything that is not reflected in the Moving Average Bollinger Band relationship anyway.
I have examined a lot of various trading ideas in my time. I have really come to the conclusion very few are any better than a 50/50 gamble. Certainly nothing I have seen is like printing money. The most consistently productive method I have been able to come up with uses over lapping layers of signals.
First, one needs to know the basics:
1. Use of trendlines, and how to trade both prices bouncing off of them, and breaking through them.
2. Support and Resistance lines generated by previous turning points, and how to trade both when the price bonces off of them, or trades through them.
3 How to spot all the major patterns, and how to trade break out confirmations of them.
4. How to generate support and resistance lines and price targets using Fibonacci numbers.
5. You need 2 to 3 indicators that you know intimately.
1 through 4 are your essential fudemental skills everyone must master.
Number 5 is very important. because those are the tools you use to weed out false signals. I personally use the Bollinger Bands, an the 4 ,9 and 18 bar moving averages. I only look at Volume to pick which contract to trade.
Some guys like to use the Williams%R, Stochastics, swing lines, and any number of others. It really does not matter which tools are your favorite. The key, in my opinion, is to know those tools inside and out, and how to use them to verify each other to weed out false signals.
The above is the easy part. The psychological aspect is the toughest. That s where the real challenge is, and what makes the difference between a professional trader, and accounts getting wiped out either quickly, or through a thousand cuts.
I am always very suspicious of claims of systems that are "Easy Money" and such. I have yet to see one pan out.
