If (conditions) then
PlotPaintBar(H,L[,O,C[,"Name"[,Color[,BackgroundColor,Width]]]]);

Normally I just do PlotPaintBar(H,L,O,C,"somename",Color);

This takes up Plots 1-4, so if you're using the same code to plot other things, start with Plot5(whatever).

Plots the angle just fine, but really should be doing SetPlotColor when the angle goes from neg. to pos., i.e. crosses to above zero. Am I overlooking some (painfully) obvious detail here? I can't imagine making the code much simpler. Inputs:Price(Close); Vars:Angle(0); Angle=ArcTangent(Price-Price[...
