What I learn from the Alvarez Factor from Steven Primo, the four main criteria?

1. Volatility - Using historical volatility calculations help, but you won't know if the volatility will be there today. And if there's no volatility, there's little to no opportunity to make money for the day.

2. Relative Strength - Does strength lead to further strength? Or does weakness lead to further strength? This has been proven with tens of thousands of examples to show you what you need to be looking for every morning in your daily trading set-ups.

3. Today's Price Movement - Most successful day traders know that the opening is many times the key to the rest of the day's movement.

4. Daily Market Direction - As most successful daytraders know, the overall market direction many times dictates the success of their results. By simply adding one simple market timing filter to the above key components, results have been improved to above 3% per trade.
