核心逻辑
该指标是一个基于MACD的增强型趋势判断指标。核心原理包括： 1. **标准MACD计算**：使用10日EMA和22日EMA计算DIF，再计算7.5日EMA作为DEA，最后用2倍(DIF-DEA)得到MACD柱状图 2. **买小卖小理念**：当股价上涨但MACD红柱堆反而变小（缩头），预示顶背离应卖出；当股价下跌但MACD绿柱堆反而变小（缩脚），预示底背离应买入 3. **背离判断**：通过比较股价与MACD/DIF的走势，判断顶背离（卖出信号）和底背离（买入信号） 4. **高低点标注**：使用TROUGHBARS和PEAKBARS函数标记波谷和波峰位置
买卖信号
**买入信号：** - DIFF上穿DEA形成金叉（低位金叉DIFF<-0.1时更可靠） - 二次金叉（21周期内出现2次金叉） - 底背离形成（股价创新低但MACD/DIF未创新低） - MACD绿柱堆缩小（缩脚） **卖出信号：** - DIFF下穿DEA形成死叉 - 顶背离形成（股价创新高但MACD/DIF未创新高） - MACD红柱堆缩小（缩头）
用法
1. **基本用法**：关注金叉买入、死叉卖出的基本MACD信号 2. **精华8字**："买小卖小，缩头缩脚"——当MACD柱子由大变小时往往是变盘信号 3. **背离交易**：重点关注底背离（买入）和顶背离（卖出）的确认 4. **二次金叉**：在零轴下方出现二次金叉是较强的买入信号 5. **辅助参考**：结合市净率、市盈率判断股价估值水平 6. **图形观察**：红柱变绿柱时考虑减仓，绿柱变红柱时考虑加仓
