Summary: Gold Scalper Safety EA is an MQL4 expert advisor for XAUUSD that combines RSI divergence detection, volatility filtering, and controlled single-position scalping. Suitable for M15 timeframe.




Gold Scalper Safety EA is engineered for traders seeking stable, low-risk scalping on XAUUSD gold. Unlike high-frequency scalpers that generate excessive commission costs, this EA focuses on high-quality reversal signals during optimal volatility windows. The strategy detects RSI oversold/overbought conditions with divergence confirmation, applies ATR volatility filters to avoid low-volatility chop zones, and uses a single position controller to prevent overtrading. Each trade includes fixed stop loss and take profit based on ATR multiples, with daily loss protection and Friday close mechanisms.

Recommended Timeframe: M15
Trading Logic:
  • RSI Reversal Detection: Wait for RSI(14) to enter oversold (<30) or overbought (>70), then return above/below threshold.

  • Divergence Confirmation: Price makes lower low but RSI makes higher low (bullish) or vice versa (bearish).

  • Volatility Filter: ATR(14) must be above minimum threshold (not too choppy) but below max (not too wild).

  • Time Filter: Trade only during active sessions (avoid Asian consolidation).

  • Risk Management: Fixed stop loss (250 points), take profit (400 points), maximum 1 trade at a time.
