Summary: Gold Signal Pro EA is an MQL4 expert advisor for XAUUSD that integrates 7 independent filters including multi-timeframe trend confirmation, RSI momentum, volatility detection and MA structure analysis. Suitable for M15 stable operation.
Gold Signal Pro EA is built specifically for XAUUSD with a rigorous 7-layer filter system to eliminate low-probability signals. Unlike typical grid or martingale EAs, this strategy prioritizes signal quality through multi-timeframe confirmation (M5 for entry, H1 for trend, H4 for primary direction), volatility regime detection, and dynamic quality scoring. Each signal comes with calculated TP/SL levels based on current ATR and market structure. The EA includes daily equity protection, spread monitoring, session-based filtering, and Friday close mechanisms.
Recommended Timeframe: M15
Trading Logic:
1. Multi-Timeframe Filter: H4 EMA(50) determines primary trend. H1 confirms intermediate direction. M5 scans for entry triggers.
2. Volatility Detection: Current ATR must not exceed 1.6x the 20-period average. Abnormal volatility spikes block trading.
3. MA Structure Check: Verify alignment of SMA 13/21/75/100. Flat MA periods automatically filtered out.
4. RSI Momentum Filter: RSI(14) must be >50 for long signals, <50 for short signals. No entry at extreme overbought/oversold.
5. Quality Scoring System: Each signal receives a score based on confluence factors (★★★ strong, ★★ standard, ★ cautious).
6. Risk Management: ATR-based dynamic stop loss (1.4x ATR), take profit (2.5x ATR). Trailing stop activates at 1x ATR profit.
