比特币K线区间稳定器EA - MQL4源码（基于K线分析的比特币交易）

Summary: 比特币K线区间稳定器EA是一款专为比特币设计的MQL4智能交易系统。分析K线区间、检测波动收缩、在区间突破时入场，适合H4周期稳定运行。




比特币K线区间稳定器EA专为比特币独特的价格行为而构建。不同于传统指标，它分析纯K线数据：区间大小、实体与影线比例以及波动收缩形态。EA识别低波动时期（压缩期），并在价格以动量确认突破既定区间时入场。动态止盈基于压缩区间大小，追踪止损在盈利达到1.5倍压缩区间后激活，锁定利润同时控制回撤。

推荐加载周期： H4
策略核心逻辑：
1. 区间检测：计算最近20根K线的平均真实区间。当当前区间 < 0.55倍平均区间时识别为盘整。
2. 压缩形态：要求至少连续3根K线的区间依次递减（波动收缩）。
3. 突破入场：当价格收盘价超出压缩期最高价或最低价至少1.5倍当前ATR时入场。
4. 风险管理：止损设在压缩区间另一侧。止盈为2.5倍压缩区间大小。盈利达到1倍压缩区间时启动追踪止损。
