Summary: 黄金K线流EA是一款专为黄金设计的MQL4智能交易系统。纯粹依赖K线形态：pin bar、内包线和关键位影线拒绝，不使用传统指标。适合H1周期。




黄金K线流EA专为黄金（XAUUSD）构建，使用纯价格行为和K线形态识别。它避免滞后指标，而是关注实时K线结构：pin bar（长影线）、内包线（压缩）以及在关键位的影线拒绝。EA基于近期摆动高点和低点跟踪动态支撑/阻力，当K线拒绝发生时入场。独特的波动率调整机制在高影响新闻时段放宽止损。

推荐加载周期： H1
策略核心逻辑：
  • 结构识别：识别最近20根K线的摆动高点和低点作为动态支撑/阻力。

  • K线拒绝形态：寻找影线长度 > 2倍实体的pin bar，收盘价靠近另一端（在支撑/阻力位拒绝）。

  • 内包线突破：当内包线（区间在前一根K线内）以强势收盘价突破母K线区间时入场。

  • 风险管理：基于ATR的动态止损（1.8倍ATR）和止盈（3.5倍ATR）。同时持仓最多1单，每日亏损上限5%。
