%B

The %B indicator is based on the position of price relative to the Bollinger Bands.

It is calculated as follows:

%B = (Price - Lower Band) / (Upper Band - Lower Band)

Example values and positions relative to Bollinger Bands:

%B = 1: The price is exactly at the upper band.
%B = 0: The price is exactly at the lower band.
%B = 0.5: The price is at the midpoint between the bands (the moving average).
%B > 1: The price is above the upper band.
%B < 0: The price is below the lower band.
