核心逻辑
这是一个基于MACD指标的增强型趋势判断指标，主要包含三个核心部分： 1. **标准MACD系统**：计算12日EMA与26日EMA的差值（DIF），再计算DIF的9日EMA（DEA），通过DIF与DEA的交叉判断趋势转折。 2. **变形MACD系统**：构建了DKK（4*DIF-3*DEA）和DDD（DKK的5日EMA）两个变形指标，用它们的交叉替代传统MACD交叉，意图更早发出信号。 3. **支撑位系统**：基于DIF的波动幅度计算动态支撑位，用于判断回调支撑。 4. **辅助KDJ**：引入14周期KDJ的J线作为辅助判断，当J线<-0.5时视为超卖。
买卖信号
**买入信号**： - DDD上穿DKK（图标2） - MACD连续4天满足DIF>0且MACD<0且MACD递减，第5天MACD回升（MACDXG2，红色柱状） - J线从高位回落连续≥3天后，J<-0.4且回升（kdjXG） - 底背离（DIF创新低但价格未创新低后金叉） - 二次金叉（DEA下方DIF上穿DEA，且21天内出现2次金叉） - "三全项"、"二全项"、"一全项"等组合信号 **卖出信号**： - DKK上穿DDD（图标1） - 顶背离（DEA创新高但价格未创新高后死叉）
用法
1. **主要用法**：关注DDD与DKK的交叉作为主要买卖信号，红钻为买入，绿钻为卖出。 2. **辅助验证**：当出现红色柱状（MACDXG2）或J线信号时，可作为买入辅助确认。 3. **背离信号**：底背离和二次金叉是较强的买入信号，可重点关注"三全项"（同时满足低金、二次金叉、底背离）是最强买入信号。 4. **支撑位**：白色水平线为动态支撑位，股价回调至此可考虑买入。 5. **红绿柱面积**：显示MACD红绿柱的堆积情况，可判断趋势力度。
