Description
Bollinger band percent (%B)
Syntax
BBPct(len, mult)
Parameters
len - lookback period
mult - number of standard deviations
Notes
This indicator returns the position of Close relative to the Bollinger bands.
This is equivalent to (Close - BBBot(len, mult)) / (BBTop(len, mult) - BBBot(len, mult)).
The return value is:
•>1 if close is above the top band
•1 if close equals the top band
•0.5 if close equals the moving average
•0 if close equals the bottom band
•<0 if close is below the bottom band
To calculate BBPct for something other than Close use BBPctF.
This function supports one-pass calculation when used in the Data Section with a non-variable count.
