通达信特色MACD指标（MACD类）指标公式

核心逻辑

这是一个基于经典MACD指标的增强版可视化指标。核心原理是计算12日EMA与26日EMA的差值（DIFF），再计算DIFF的9日EMA（DEA），通过两者的差值绘制MACD柱状图。指标还包含：①低位金叉（DIFF上穿DEA且DIFF<-0.1）用于捕捉超跌反弹；②二次金叉（21天内第二次金叉且DEA<0）用于确认底部；③底背离/顶背离用于判断趋势反转；④在图表上标注死叉/金叉后第1、3、5、8、13、21等关键天数，帮助投资者把握时间窗口。

买卖信号

**买入信号：** - 低位金叉：DIFF上穿DEA，且DIFF值<-0.1（超跌反弹信号） - 二次金叉：21天内出现第二次金叉，且DEA<0（底部确认信号） - 底背离：股价创新低但DIFF未创新低后出现金叉（趋势反转信号） - 金叉买入：金叉时显示白色"1"字买入提示 **卖出信号：** - 顶背离：股价创新高但DIFF未创新高后出现死叉 - 死叉卖出：DIFF下穿DEA时显示绿色图标 - 死叉后关键天数：标注1、3、5、8、13、21等天数提醒可能变盘

用法

1. **基础用法**：DIFF上穿DEA（金叉）买入，下穿DEA（死叉）卖出 2. **低位金叉**：在DIFF<-0.1区域出现金叉时，是较强的买入信号 3. **二次金叉**：在下跌趋势中出现二次金叉，往往是趋势由空转多的重要信号 4. **背离信号**：底背离是买入机会，顶背离是卖出机会 5. **时间窗口**：关注死叉/金叉后第1、3、5、8、13、21、34、55、68天，这些天数常出现变盘 6. **颜色判断**：蓝色系柱状图表示多头力量，橙红色系表示空头力量
