EURUSD Trend Guard EA is specifically designed for EURUSD with a low-risk, stable operational approach. It incorporates trend filtering, volatility-based entry, and strict money management suitable for the moderate volatility and mean-reverting nature of EURUSD. The EA trades only in the direction of the major trend (EMA50) and uses ATR to avoid trading during extreme volatility. Each trade has a fixed stop loss and take profit, with a daily equity protection mechanism and spread filter.
Recommended Timeframe: H1
