Volatility
Bollinger %b
%bShows where the current close sits within the Bollinger Bands on a 0–1 scale: 0 means price is at the lower band, 1 means it is at the upper band. Values below 0 or above 1 indicate the price has broken outside the bands.
Tips
%b below 0 during a downtrend confirms a band-riding breakdown; avoid buying just because it looks “oversold”
Combine %b with BBW: a %b extreme while BBW is narrow (squeeze) is a high-probability breakout setup
