通达信MACD背离三全项指标（MACD类）指标公式

买卖信号

**买入信号：** 1. **低位金叉**：CROSS(DIFF,DEA) AND DIFF<-0.1（DIFF在低位金叉DEA） 2. **二次金叉**：CROSS(DIFF,DEA) AND DEA<0 AND COUNT(JCCOUNT=2,21)=1（21周期内第二次金叉） 3. **底背离**：REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA) 4. **三全项**：低位金叉 AND 二次金叉 AND 底背离（三个条件同时满足） **卖出信号：** 1. **顶背离**：REF(CLOSE,A2+1)<CLOSE AND REF(DIFF,A2+1)>DIFF AND CROSS(DEA,DIFF)

用法

1. **适用场景**：该指标为MACD指标的优化版本，适用于中短线趋势判断和波段操作 2. **核心用法**： - DIFF与DEA金叉时考虑买入，死叉时考虑卖出 - 关注"低位金叉"和"二次金叉"信号，后者表示更强的买入信号 - 底背离（股价创新低但DIFF未创新低）是重要的买入信号，顶背离是卖出信号 - "三全项"信号（同时满足低位金叉、二次金叉、底背离）是较强的买入确认信号 3. **注意事项**： - 绿线（DIFF-DEA）下跌对应顶背离风险，红线上涨对应底背离机会 - 背离信号需要结合成交量和其他指标综合判断 - 二次金叉需配合DEA<0且在21周期内只出现一次
