Summary: EURUSD TriCore EA is an MQL4 expert advisor for EURUSD that integrates EMA trend, stochastic oscillator and candlestick confirmation. Designed for stable, low-risk operation on H1.




EURUSD TriCore EA integrates three complementary logics: trend following (EMA), momentum/mean reversion (Stochastic) and price action confirmation (candlestick patterns). The EA only enters trades when all three conditions align, reducing false signals. It includes ATR-based volatility filtering, daily loss limit, spread control and Friday close protection. The strategy aims for steady, compounding growth rather than high-frequency trading.

Recommended Timeframe: H1
Trading Logic:
  • Trend Filter: EMA(50) determines direction (price above = long only, below = short only).

  • Stochastic Filter: Stochastic(14,3,3) must be below 20 for long (oversold) or above 80 for short (overbought).

  • Candlestick Confirmation: Bullish engulfing or hammer for long; bearish engulfing or shooting star for short.

  • Risk Management: Fixed stop loss (250 points), take profit (450 points). Maximum 1 trade at a time, daily loss limit 5%, max spread 25 points.
