Here is the call to bollinger bands from the manual:

Code:

BBands(vars Data, int TimePeriod, var NbDevUp, var NbDevDn, int MAType)

The return values are stored in: rRealUpperBand, rRealLowerBand, rRealMiddleBand.

Call BBands and subtract rRealLowerBand from rRealUpperBand and viola, bollinger band width.

Cheers,
BobbyT

Most sources I find use the formula

Band Width = (Upper Bollinger Band - Lower Bollinger Band) / Middle Bollinger Band
