Summary: 比特币趋势卫士EA是一款专为BTCUSD设计的稳定趋势跟踪MQL4智能交易系统。使用三重EMA、ADX过滤和动态仓位管理，适合H4周期。




比特币趋势卫士EA是为比特币独特的市场行为设计的稳健趋势跟踪系统。该EA使用三重EMA云（快、中、慢）识别趋势方向和动量，结合ADX过滤震荡市场。基于ATR的动态止损适应比特币的高波动性，而波动率调整的仓位管理在剧烈波动期间降低风险敞口。系统包含权益保护、点差控制和周末持仓关闭，以管理加密特有的风险。

推荐加载周期： H4
策略核心逻辑：
  • 三重EMA趋势：上涨趋势要求EMA9 > EMA21 > EMA55；下跌趋势要求EMA9 < EMA21 < EMA55。

  • 趋势强度：ADX(14)必须大于25，做多时+DI > -DI，做空时-DI > +DI。

  • 入场确认：价格必须在回调后收盘于慢EMA之外（不在首次触碰时开仓）。

  • 风险管理：动态止损为2.5倍ATR，止盈为5倍ATR，盈利达到3倍ATR后启动追踪止损。最多持仓1单，每日亏损上限5%，每周亏损上限10%。
