So, UB is the z = k limit and LB is the z = - k limit. The %b is: %b = (x − LB) / (UB − LB) = (mu + z*sigma - mu + k*sigma)/(mu + k*sigma - mu + k*sigma) = (z + k) / 2k. The bandwidth (BW) is:

Bollinger Bands comprise a moving average and the moving standard deviation of the same time window as the moving average that it is using. Then, Bollinger Bands are plotted two standard deviations above and below the moving average on the price time series chart. We will use a 20-day time window for computing Bollinger Bands. The code to
What Bollinger Bands look like Source: Fidelity Learning Center Bollinger Bands are plotted at a standard deviation above and below a simple moving average of the price. The upper band is the moving average plus a standard deviation, and the lower band is the moving average less the standard deviation.
If the price then moves below the low of the prior pullback, the M-Top is in place as shown in the figure below. Bollinger - Chart Source: Stockcharts.com
