Summary: EURUSD趋势稳定EA是一款专为EURUSD趋势交易设计的MQL4智能交易系统。使用Supertrend指标作为主信号，配合ADX趋势强度过滤和ATR动态止损，适合H1周期。




EURUSD趋势稳定EA专为欧美（EURUSD）稳定趋势交易而设计。该EA使用Supertrend指标作为主要趋势方向信号，结合ADX（平均趋向指数）确保只在足够趋势强度时开仓。基于ATR的动态止损能够适应市场波动，而保本机制在价格有利移动后保护本金。EA同时只持有一单，并包含每日亏损保护。

推荐加载周期： H1
策略核心逻辑：
  • 趋势方向：Supertrend（ATR周期10，倍数3）判断趋势方向（绿色=上涨，红色=下跌）。

  • 趋势强度：ADX(14)必须大于25确认趋势市场存在。

  • 入场信号：价格收盘于Supertrend线之外，且ADX确认趋势强度，无现有持仓。

  • 风险管理：基于ATR的止损（2倍ATR），止盈3.5倍ATR，盈利达到1.5倍ATR后移动至保本。
