Hi Marshall,
No, I dont have any special expertise with them -
there was a recent question asking if it was possible to draw the bands so that
85% of the bars would be automatically included - I just thought it might
be interesting to try and write the code.

Steve, A rhetorical question, but; Have you worked with
the bands long enough to have some comments on how they should be
worked and evaluated for best performance. I have been
trying it as an indicator with subtle results, even a little
confusion. Marshall

I sent it as an attachment. If you dont
