Interesting concept. Sideways seems to be filtered by many opposite cycle alerts in a row, which settings do you use? Sal uses Super signals as the band indicator. I prefer faster non-repainting atr-bands.
I tested similar spike finder. As vertex repaints, Extreme Cycle 2 indicator can be set up non-repainting. Extreme 3 only the thick lines repaint, I think. I added ! to the names to keep them in front on mt4 navigator.
