Summary: Gold Horizon EA is an MQL4 expert advisor for XAUUSD that uses multi-timeframe EMA trend confirmation, ATR-based dynamic stops, and daily loss limits. Suitable for H1 timeframe stable operation.




Gold Horizon EA is designed specifically for gold (XAUUSD) to achieve stable, low-risk operation by focusing on trend alignment and volatility awareness. Unlike aggressive grid or martingale systems, this EA prioritizes signal quality over trade frequency. It uses multi-timeframe trend confirmation (H1 and H4 EMAs) to ensure alignment with the broader market direction. An ATR-based volatility filter prevents entries during excessive market noise, while a dynamic ATR stop loss adapts to current gold volatility. The EA includes daily equity protection, spread control, and Friday close mechanisms to safeguard against weekend gaps.

Recommended Timeframe: H1
Trading Logic:
  • Multi-Timeframe Trend: H4 EMA(50) determines the primary trend direction. H1 must trade in the same direction.

  • Momentum Filter: RSI(14) must confirm momentum (>50 for long, <50 for short).

  • Entry Trigger: Price retraces to H1 EMA(20) and closes beyond it in the trend direction.

  • Volatility Guard: Current ATR(14) must not exceed 1.8x the 20-period average ATR.

  • Risk Management: Dynamic stop loss at 1.5x ATR, take profit at 3x ATR. Trailing stop activates after 1x ATR profit.
