I used to keep track of ATR in ES and I really have never found a practical way to use it consistently.
As far as CL, which is much less mean-reverting than ES, how do you guys actually make use of ATR? Surely we're not fading and averaging at multiples of ATR ...
For me, it is pure hindsight -- I don't use ATR in trading per se, but in system design, and also in evaluating whether CL is a good candidate to trade, ATR is significant.
