通达信macd优化指标（MACD类）指标公式

买卖信号

**买入信号：** 1. 低位金叉：DIFF与DEA在低位金叉（DIFF<-0.1） 2. 二次金叉：零轴下方二次金叉 3. 底背离：MACD底背离信号 4. 三全项：同时满足低位金叉、二次金叉、底背离三个条件 5. AD条件：满足特定条件的买入信号（MACD连续两天大于0且股价创14日新低） 6. DRAWICON(CROSS(DIFF,DEA),DEA,1)：金叉买入图标 **卖出信号：** 1. 顶背离：MACD顶背离信号 2. DRAWICON(CROSS(DEA,DIFF),DEA,2)：死叉卖出图标

用法

1. 本指标是基于经典MACD指标的优化版本，包含标准MACD的所有功能 2. **低位金叉**：在DIFF<-0.1的低位出现金叉时，是较强的买入信号 3. **二次金叉**：在零轴下方出现第二次金叉，预示趋势可能反转 4. **底背离**：股价创新低但MACD未创新低，是典型的买入信号 5. **三全项**：同时满足低位金叉、二次金叉、底背离三个条件时，是非常强的买入信号 6. **AD条件**：特定环境下（MACD由负转正且股价创短期新低）的买入机会 7. 顶背离是卖出信号，提示股价可能见顶 8. 可结合金叉死叉进行短线操作，也可结合背离判断趋势反转
