yeah, i will continue to change parameters, but it looks like whatever i do it never penetrates the BB. For BB i need a setting 10, 2 and sma. the whole idea here is to trade from penetrations. again, if you already spent some time playing with different linear regressions, maybe you can come up with somehting. the 2 indicators you suggested are very similar to what i need i just cannot get them to pop up from BBs. thanks for your help.
