Bollinger Band Squeeze Strategy

This setup monitors the width of the Bollinger Bands to detect periods of low volatility. When the bands contract relative to their recent average, it signals a potential volatility expansion is near.

Once a squeeze is identified, the strategy waits for price to break outside the bands. A close above the upper band initiates a long, while a close below the lower band opens a short. The trade is closed if price returns toward the middle of the bands or if a stop-loss is triggered.

The method targets traders who like to trade volatility breakouts rather than trend continuation. Using the band width as a filter helps avoid false signals during choppy conditions.
