Summary: 黄金突破引擎EA是一款专为XAUUSD设计的MQL4智能交易系统。识别波动率压缩突破，配合Order Block趋势确认和ATR动态网格管理，适合M15周期。
黄金突破引擎EA专为XAUUSD设计，融合三大核心模块：波动率压缩突破检测、Order Block趋势过滤、以及ATR自适应网格回血。EA首先识别波动率压缩形态（区间收窄），然后通过简化的Order Block概念（近期摆动高低点结构）确认突破方向，最后用ATR自适应网格管理交易序列，在达到盈利目标时平仓所有订单。这种多层过滤机制减少了假突破，而受控的网格结构有助于挽回回撤且不产生无限风险。
推荐加载周期： M15
策略核心逻辑：
1. 波动率压缩：检测当前ATR(14)是否低于过去20根K线平均ATR的0.65倍。
2. 突破方向：当价格收盘高于压缩期间最高点→潜在买入；低于压缩期间最低点→潜在卖出。
3. Order Block过滤：确认近期摆动结构支持突破方向（价格已突破前期关键水平位）。
4. 网格执行：首单设固定止损（ATR×1.2），后续按ATR距离间隔加仓，手数1.5倍递增（最多3层）。
5. 止盈退出：当总浮动盈利达到账户余额的1%时，或单笔止盈触发时，平仓全部订单。
