Re: Bollinger Band Width

[Ted Reback <treback@xxxxxxxxxxxxxx>]

Brooke,

Sorry, but your formula for the width is wrong. You have to subtract the lower
band from the higher band, so the net (after elimination) width is

4 * (std(c,20))

didn't post this to the metastock list, so you might want to. Maybe you've been
working too hard on your TAOTL presentations :)).
