Gold High-Yield Hunter EA - High Profit MQL4 Source Code for XAUUSD

Summary: Gold High-Yield Hunter EA is a high-profit MQL4 expert advisor for XAUUSD. It uses breakout from 20-period high/low with martingale recovery and trailing stop. Suitable for M15 timeframe.




Gold High-Yield Hunter EA is designed specifically for gold (XAUUSD) to capture high-profit opportunities while maintaining low risk through smart position sizing. The EA uses a breakout strategy based on 20-period high/low channel with a confirmation filter. When a breakout occurs, it enters with a base lot. If the trade goes against the position, a controlled grid recovery system activates with increasing lot size but capped at maximum levels. A dynamic trailing stop locks in profits as price moves favorably. The EA includes daily profit target and drawdown protection to secure gains.

Recommended Timeframe: M15
Trading Logic:
1. Breakout Detection: Price closes above 20-period high → buy; below 20-period low → sell.
2. Confirmation: Second consecutive close beyond the level for fakeout reduction.
3. Grid Recovery: If position moves against by RecoveryStep points, open additional layer with lot multiplier (max 3 levels).
4. Risk Control: Max spread 40 points, daily profit target 10% (auto-stop trading), daily loss limit 5%, maximum grid levels 3.
