Bollinger Bands in TradingView: Squeeze, Breakout & Reversion

Bollinger Bands = a 20-period MA ± 2 standard deviations. They don't draw support and resistance — they draw the boundary of volatility. Get that and all three patterns click.

Three patterns

1. Squeeze: bands narrow to their tightest, volatility compressed; wait for a candle body to close outside the range (not a wick), then trade the breakout with a stop back inside. The squeeze foretells "a move is coming," not the direction — pre-betting direction is the main way to lose;
2. Walking the band: in a strong trend price hugs the upper/lower band. "Touched the upper band = overbought = short" is the most expensive misread — change your exit to "a close back to the middle band";
3. Mean reversion: only in a clear range (flat bands, price crossing the middle repeatedly): trim at the upper, add at the lower, middle as target; stop the moment the bands open up.
