See, I am not always looking for the cross overs. I have a list of exits. For example, a price bar opening with a gap above the upper Bollinger band (bull market) is one of my exits. So by the time the price tests the 4MA, I am already out. Cross overs for me, are for when I am looking for potential contrarian trades. For those, I look for what I call "Spear Points". That is where the 4SMA turns sharply into the bottom, or top of the price bar.
Honestly, I could probably super simplify my trading, and boost my performance simply by ignoring everything but the spear point trades. They don't come up as often as I like, and I am antsie though.
