比特币趋势坚甲EA - 稳定趋势跟踪MQL4源码（BTCUSD）

Summary: 比特币趋势坚甲EA是一款稳定趋势跟踪型MQL4智能交易系统。结合双EMA趋势检测、ADX强度过滤和ATR动态止损，适合H4周期。




比特币趋势坚甲EA专为比特币（BTCUSD）的稳定趋势自动化交易而设计。与高频或网格策略不同，本EA专注于捕捉持续的中期趋势，同时避免假突破和高波动震荡。系统使用双EMA交叉判断趋势方向，ADX过滤弱势/非趋势市场，ATR用于动态止损止盈。独特的波动率动态手数在比特币波动飙升时自动降低敞口。EA包含每日最大回撤保护、点差控制和周末跳空规避。

推荐加载周期： H4
策略核心逻辑：
1. 趋势检测：EMA(20)与EMA(50)交叉确认趋势方向。
2. 趋势强度：ADX(14)必须大于25，确保处于趋势市场。
3. 入场信号：交叉确认后，等待价格回调至EMA20（价格触及或接近），配合MACD动量确认（做多时MACD柱为正且上升，做空时为负且下降）。
4. 风险管理：动态止损为入场价2倍ATR，止盈为4倍ATR。盈利达到1.5倍ATR后启动追踪止损。当ATR超过平均ATR的1.5倍时自动减小手数。
