Steve:
There was one published in TASC and at the Equis web site. As I recall it
went something like this:
A formula for the upper BB
A formula for the lower BB
subtract the lower from the upper.
If you cant find it, let me know and I'll try to dig it up. I think that
the graph is very similar to an macd except that all the values are above
the zero line.
