Can anyone help me to get the AFL for Bollinger Bandwidth and %b. I am confused because there is a lot %b in AFL library. I need the original %b.

Thanx in advance
Azeem

Well, both formulas are just one line. Where is the problem? Where are you stuck?
Have you found the general formulas of %B and BB width?

bbPercent = 100 * ( C - bbBottom ) / ( bbTop - bbBottom );
