Bitcoin Trend Guardian EA is designed specifically for Bitcoin (BTCUSD) with a low-risk, stable operational approach. Bitcoin is extremely volatile, so this EA uses a strong trend filter (EMA100), ATR-based volatility detection to avoid extreme moves, and a fixed stop loss with wider protection. Each trade follows the major trend, with daily equity protection, maximum spread control, and Friday close.
Recommended Timeframe: H4
