Breakout

A breakout occurs when price moves beyond a defined support or resistance level, typically accompanied by increased momentum and volume. Breakouts signal the start of a new trend or the continuation of an existing one. The challenge is distinguishing genuine breakouts from false ones that quickly reverse.

How Breakouts Are Used in Trading

The Bollinger Band squeeze is a classic breakout setup. When bands narrow significantly (low standard deviation), it indicates compressed volatility that must eventually expand. Traders enter in the direction of the breakout once price exits the bands, with the ATR helping set appropriate stop-loss distances.

False breakouts are the primary risk. Price may briefly pierce a level then reverse, trapping traders. To filter false breakouts, require confirmation: a close beyond the level (not just a wick), expanding ATR, and rising ADX. Some traders wait for a retest of the broken level before entering.

Algorithmic breakout systems often combine range detection (narrow Bollinger Bands or low ATR) with directional filters. Only take breakouts in the direction of the higher-timeframe trend. This dramatically reduces false breakout exposure while capturing the strongest moves.
