I forget where I read it. Some guy went back and figured the average daily range for SP. Then he found out that when SP exceeds it's average daily range by say 10%(or something), 55% of the time (or some more than 50% number) it goes on to exceed the range in the direction of the breakout by 25% (or some number).
So it turns out to be a nice testable breakout system.
