黄金K线稳定器EA - MQL4源码（纯K线形态黄金交易）

Summary: 黄金K线稳定器EA是一款专为XAUUSD设计的MQL4智能交易系统。识别孕线形态、动量K线和假突破拒绝信号，适合H1周期稳定运行。




黄金K线稳定器EA专注于纯K线分析，不使用传统指标。它识别孕线（窄幅盘整）、动量K线（实体大、影线小）以及假突破拒绝信号（价格刺穿区间但收盘回归）。EA等待压缩形态（孕线）出现，随后动量K线突破区间，在价格回踩确认时入场。基于孕线区间的动态止损和风险控制的盈利目标确保了稳定性。

推荐加载周期： H1
策略核心逻辑：
1. 孕线检测：当前K线最高价 ≤ 前一根K线最高价，且最低价 ≥ 前一根K线最低价。
2. 压缩确认：要求孕线实体的体幅比 > 0.6（强盘整）。
3. 动量信号：下一根K线收盘价高于孕线高点（做多）或低于孕线低点（做空），且实体 > 2倍影线。
4. 回踩入场：等待价格回测被突破的区间边界（50%-80%回撤幅度）再入场。
5. 风险管理：止损设在孕线区间另一侧，止盈为2倍孕线区间，盈利达到1倍区间后启动追踪止损。
