Summary: Gold Aegis EA is an MQL4 expert advisor for XAUUSD that combines multi-timeframe EMA trend filters, ATR volatility guard, controlled layering, and basket take profit. Suitable for H4 timeframe stable operation.




Gold Aegis EA is engineered for stable, long-term gold trading with a focus on capital preservation. Unlike aggressive grid or martingale systems, this EA employs a disciplined trend-following approach with multiple safety layers. It waits for high-quality breakout structures confirmed across H1 and H4 timeframes, then enters with a controlled layering system that limits maximum exposure. The EA includes ATR-based dynamic stops, volatility filtering, basket profit protection, and daily equity safeguards. This design prioritizes consistency over frequency, making it suitable for traders who value steady account growth.

Recommended Timeframe: H4
Trading Logic:
  • Multi-Timeframe Confirmation: H4 EMA(200) defines macro trend; H1 must align with same direction.

  • Breakout Detection: Identify fresh swing highs/lows over the last 20 candles.

  • Entry: Place pending stop orders beyond identified structure levels, confirmed by ADX(14) > 25.

  • Controlled Layering: Maximum 2 additional positions (3 total), fixed lot size (no martingale).

  • Risk Management: ATR-based stop loss (1.5x ATR), basket take profit mechanism, daily loss limit 5%.
