A Bollinger squeeze is when the bands narrow sharply, showing that volatility has collapsed and price is coiling in a tight range. Markets alternate between quiet and active phases, and an unusually tight squeeze often precedes an expansion in volatility — a breakout move.
Why the squeeze works
During a squeeze, buyers and sellers reach a temporary balance and orders build up on both sides of a tight range. When one side finally wins, the pent-up energy releases into a directional move and the bands snap open. The squeeze tells you a move is likely — it does not tell you the direction.
Entry and stop logic
A disciplined plan waits for a candle to close outside the range that formed during the squeeze, then enters in the breakout direction with a stop on the opposite side of the range. Because the squeeze is directionless, aligning the breakout with the higher-timeframe trend improves the odds and reduces false starts.
- Squeeze = bands pinch tight = volatility compressed.
- Signals that a move is likely, but not which way.
- Enter on a close outside the range; stop on the opposite side.
- Favour breakouts that agree with the larger trend.
A squeeze warns that a volatility expansion is coming — trade the confirmed break out of the range, with a stop on the other side, not a guess at direction.
Squeezes produce false breakouts too, where price pokes out and snaps back. That is exactly why waiting for a close and defining your invalidation before you enter matters — no squeeze guarantees the move sticks.
