Bollinger Bands

55
Bollinger Bands is a clean, beginner-friendly Bollinger Bands indicator that adds practical squeeze detection and simple breakout logic without cluttering your chart. It plots the classic upper and lower bands with an optional basis line and band fill, then detects volatility compression using a Keltner Channel squeeze (BB inside KC) with optional background shading so you can instantly spot “quiet” market phases. It also includes breakout and re-entry conditions (back inside the bands) plus ready-to-use alerts for breakouts and squeeze on/off events. An optional Live Levels mode displays the current Upper/Lower/Basis as anchored reference lines for quick decision-making.
