通达信淘底擒牛指标（MACD类）指标公式

📅 2026-07-23

核心逻辑

该指标是一个复合型趋势动量指标，结合了MACD和RSI的思想： 1. **A1和B1部分**：类似MACD原理，用7日EMA与21日EMA的差值（A1）作为快线，再用平滑处理得到信号线（B1），用于判断短期趋势方向和动量 2. **RSI部分**：计算1-21日共15个周期的RSI值，取平均得到短线RSI（1-5日）和中线RSI（6-21日），用于判断超买超卖状态 3. 通过颜色柱状图展示多空力量变化，红色代表多头增强，绿色代表空头增强

买卖信号

**买入信号：** - B1上穿0轴且B1>前一天（B1>REF(B1,1) AND CROSS(B1,0)）：显示买入图标 - 短线RSI上穿中线RSI（A条件） - B1<0且向上拐头（B1<0 AND B1>REF(B1,1)）：黄色柱 **卖出信号：** - 短线RSI下穿中线RSI（B条件） - B1>0且向下拐头（B1<REF(B1,1) AND B1>0）：绿色柱

用法

1. **零轴判断**：B1在0轴上方为多头趋势，下方为空头趋势 2. **金叉买入**：B1上穿0轴时买入，或关注RSI短线上穿中线的信号 3. **趋势确认**：结合STICKLINE颜色，红色柱表示多头动能增强，可持有；绿色柱表示空头增强，需警惕 4. **RSI配合**：当RSI在50以上且多头排列时趋势更强
