Summary: Gold Horizon EA is an MQL4 expert advisor for XAUUSD that combines EMA trend detection, RSI momentum confirmation, and ATR volatility filtering. Suitable for H1 timeframe with daily risk controls.




Gold Horizon EA is a stable, low-risk automated trading system designed specifically for Gold (XAUUSD). Unlike aggressive grid or martingale systems that can blow accounts during sustained trends, this EA follows a disciplined trend-confirmation approach . It combines three core filters: EMA trend direction, RSI momentum, and ATR volatility guard to ensure entries only occur in favorable market conditions. Every trade has a fixed stop loss and a 2:1 risk-reward take profit. The EA also includes a daily loss limit, spread control, and Friday close protection to avoid weekend gaps.

Recommended Timeframe: H1

Trading Logic:
  • Trend Filter: 50-period EMA determines direction (price above = long only, below = short only).

  • Momentum Confirmation: RSI(14) must be above 55 for long entries or below 45 for short entries to avoid low-momentum zones.

  • Volatility Guard: ATR(14) must be below 1.8x its 20-period average to skip extreme volatility.

  • Entry: After both conditions align, enter on the next bar open with fixed SL/TP.

  • Risk Management: Fixed stop loss (350 points), take profit (700 points). Daily loss limit 5%, max spread 35 points.
