买卖信号
1. **低位金叉**：DIFF与DEA在低位（DIFF<-0.1）发生金叉（COLORMAGENTA粗线条+CROSSDOT标记） 2. **二次金叉**：零轴下方（DEA<0）出现第二次金叉（COLORFF00FF粗线条+CROSSDOT标记） 3. **底背离**：股价创新低但DIFF未创新低，且DIFF与DEA金叉（COLORRED粗线条+CROSSDOT标记） 4. **顶背离**：股价创新高但DIFF未创新高，且DEA与DIFF死叉（COLORF08000粗线条+CROSSDOT标记） 5. **零下二次金叉**：21周期内出现2次零轴下方金叉的过滤信号（COLORWHITE粗线条+CROSSDOT标记）
用法
1. **适用场景**：中短期趋势交易，主要用于判断MACD金叉死叉及背离信号 2. **买入时机**： - 低位金叉信号出现时考虑买入 - 底背离信号是较为可靠的买入信号 - 零轴下方二次金叉表明反弹可能增强 3. **卖出时机**： - 顶背离信号出现时考虑减仓或卖出 4. **注意事项**： - 该指标为MACD的变种，在传统MACD基础上增加了背离识别和二次金叉过滤 - 公式中绿色STICKLINE表示MACD<0且下降，红色表示MACD>0且上升 - 背离信号需结合成交量和其他指标综合判断 - 二次金叉信号使用FILTER过滤，可减少虚假信号
