Don't worry about being an Newb - I'm only 5 seconds ahead of you -
ask away - you might not always get an answer if no one is around.
Apologies - there was an error in my code.
Midpoint = (H+L)/2; so my answer would plot as a constant 2.
Try this:
//To plot BarRange% as an indicator
//Change Periods as required or use Param function
Periods = 100;
Range = H-L;
MidPoint = (H+L)/2;
BarRangePercent = Range/MidPoint * 100;
AveBarRangePercent = MA(BarRangePercent,Periods);
//Plot(AveBarRangePercent, "AveBarRangePercent", colorBlue,1);
//To Plot BarRange% as a band
AveUpperBarRangePercent = AveBarRangePercent/2;
BarRangeUpperBand = Midpoint * (1 + AveUpperBarRangePercent/100);
Plot(BarRangeUpperBand,"BarRangeUpperBand",colorBlue,1);
If you slide it onto a chart it will plot the upper band - I left the
lower band for you to work out yourself (1-etc).
If you want to plot it as an indicator then comment out the lower
plot and uncomment the upper.
Good luck with AB and your trading.
