Cardwell Style RSI / Organized & Primed For A Break. I have published several charts on this action and as a flip book it should start presenting information on how to construct an actionable on "when" to enter. There are some schools that teach this on the theory of pull-back buying, you know the "buy on the dips," but you don't always know if this the final, final dip. And every trader asks themselves "is this the best price I can buy?" Long on the cross. Strong pull-back if rejected.
