Steve, thanks, I was trying the bands with several different stocks and find that the results need to be correlated with other indicator results. Only then did it seem that the results were effective in the long(Buy) or short(sell) determination. I will keep looking at it and let you know if you have come up with a crystal ball that is not visible as of yet. Thanks for your interest. Marshall

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
