Volatility-squeeze breakout EA: Bollinger width / Keltner squeeze, expansion breakout with the EMA trend, stop trailed on the middle band.
GoldLab Bollinger Squeeze is a fully automated Expert Advisor for MetaTrader 5. It is designed for XAUUSD (gold) and also runs on other symbols such as EURUSD.
How it trades
- Squeeze detection - volatility is considered compressed when the Bollinger Band width is near its lowest of the last N bars, and/or when the Bollinger Bands sit inside a Keltner Channel (EMA +/- ATR). You choose which definition to use.
- Expansion breakout - within a few bars after a squeeze, a candle must close outside the Bollinger Band (a fresh close, not a bar that was already outside).
- Trend filter - longs only above a rising trend EMA (default 100), shorts only below a falling one. Can be switched off.
- Stop-loss at the Bollinger middle band (with a minimum ATR distance). Optional take-profit at an R-multiple (default 3R; set 0 to exit only by trailing).
- Trailing - on every new bar the stop is moved to the middle band (plus a small ATR buffer) when that tightens it, so trades are held while the expansion continues and closed when price falls back through the middle of the bands.
Risk management (built in)
- Every trade is opened with a stop-loss. There is no martingale, no grid and no averaging down.
- Position size from risk % of balance (default 1%) or a fixed lot; lots are normalised to the broker's min / max / step and reduced if free margin is not enough.
- Daily loss limit: no new trades for the rest of the day once equity is down the set % from the day-start balance.
- Max spread filter, optional trading-hours filter, and no orders while the market is closed or trading on the symbol is disabled.
- Stop-loss / take-profit are always placed outside the broker's stops and freeze levels.
- Works on hedging and netting accounts (on netting accounts it opens only when the symbol has no position).

Important notes
- No trading system can guarantee profit. Past performance, in the tester or live, does not guarantee future results.
- Always test the EA in the MetaTrader 5 Strategy Tester and then on a demo account before using real money, with your broker's own data and spread.
- Session hours are in your broker's server time - check your broker's time zone and adjust the hour inputs if needed.
- Start with a low risk % and use money you can afford to lose.
