BBPct

Category

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.

Example

BPct: BBPct(20, 2)
