BTC波动导航者EA - 比特币自动化交易MQL4源码

Summary: BTC波动导航者EA是一款专为比特币设计的MQL4智能交易系统。使用布林带波动率收缩突破、RSI动量确认和动态仓位管理，适合H4周期自动运行。




BTC波动导航者EA专为比特币独特的市场行为而构建：高波动性、频繁跳空和强烈的趋势持续性。EA检测波动率收缩期（布林带收窄），并在RSI动量确认下进行突破入场。动态仓位管理机制在极端波动期间减少敞口。系统包含基于ATR的硬止损、保护利润的追踪止损以及保护资金的一周回撤限制器。

推荐加载周期： H4
策略核心逻辑：
1. 波动率收缩：布林带(20,2)带宽低于50根K线平均带宽的0.3倍。
2. 突破入场：价格收盘于上轨之上做多，或收盘于下轨之下做空，且RSI(14)做多>55、做空<45。
3. 动态手数：基础手数 = 每$2000权益0.01手。当ATR超过平均值的1.5倍时，手数减少50%。
4. 风险管理：止损2.5倍ATR，止盈5倍ATR。盈利达到2.5倍ATR后启动追踪止损。每周亏损上限10%。
