Description
Bollinger band width
Syntax
BBWIDTH(len, mult)
Parameters
len - lookback period
mult - number of standard deviations
Notes
This indicates the width of the Bollinger bands relative to the average price that they surround.
This is equivalent to 100 * (BBTOP(len, mult) - BBBOT(len, mult)) / Avg(C, len).
To calculate BBWIDTH for something other than Close use BBWidthF.
This function supports ultra-fast one-pass calculation when used in the Data Section with a non-variable count.
