Summary: 黄金K线稳定EA是一款专为XAUUSD设计的MQL4智能交易系统。仅使用纯K线价格行为：内含K线突破形态和Pin Bar反转形态，适合H1周期稳定运行。




黄金K线稳定EA完全基于K线价格行为构建，不使用传统指标。它在黄金上识别两种高概率K线形态：内含K线（盘整后突破）和Pin Bar（拒绝/反转信号）。EA使用基于ATR的波动率确认来过滤交易，并包含一个可选移动平均线趋势背景过滤器。每笔交易根据形态的最高/最低价设置固定止损，止盈为2倍风险。EA包含净值保护、点差过滤和周五平仓机制。

推荐加载周期： H1
策略核心逻辑：
  • 内含K线形态：当前K线完全包含在前一根K线范围内。当价格突破母K线最高/最低价并伴随1.5倍ATR确认时入场。

  • Pin Bar形态：影线长度≥2倍实体的K线。在影线相反方向收盘时入场。

  • 趋势过滤（可选）：使用EMA(50)，价格高于EMA只做多，低于EMA只做空。

  • 风险管理：止损设在形态极点（内含K线为母K线高低点，Pin Bar为影线末端）。止盈为2倍止损距离。
