Overview

Bollinger Squeeze measures normalized band width to detect squeeze conditions where the bands contract to their narrowest point over a specified historical lookback period. The script plots the basis line and upper/lower channel boundaries directly on the price chart, filling the space between the bands. When a squeeze is detected, it highlights the chart background to signal potential upcoming volatility expansion.
