This is the basic %b formula:
%b = (close – lower band) / (Upper band – lower band)
For the basic %b formula, we multiply the %b result with 100 to get an oscillator moving between 0 and 100 (with overshoots):
{The upper band}
upper:=2*Stdev( CLOSE,20 ) + Mov(CLOSE,20,SIMPLE);
{The lower band}...

Bollinger Bands were developed by John Bollinger and are envelopes that are plotted at two (2) standard deviation levels above and below a moving average. The CCT Bollinger Band Oscillator reconfigures the classic bands. The new indicator constructs two (2) parallel lines instead of the erratic...
