通达信MACD超准指标（MACD类）指标公式

买卖信号

1. **低位金叉**：DIFF与DEA在低位（DIFF<-0.1）形成金叉 2. **二次金叉**：DEA<0时，21日内出现第二次金叉 3. **底背离**：价格创新低但DIFF未创新低，且DIFF上穿DEA 4. **顶背离**：价格创新高但DIFF未创新高，且DEA上穿DIFF 5. **零下二次金叉**：21日内出现2次零下金叉（FILTER过滤）

用法

该指标是基于MACD的优化指标。**低位金叉**和**二次金叉**为买入信号，**底背离**为强烈买入信号；**顶背离**为卖出信号。**零下二次金叉**需配合其他指标综合判断。适用于震荡市和趋势反转的判断，零轴下方金叉信号可信度较高。可结合DRAWLINE绘制的支撑/压力线分析趋势延续性。
