核心逻辑
该指标是一个复合型技术指标，主要由两部分组成： 1. **趋势判断部分（A1、B1）**：类似MACD的变形指标，用7日EMA和21日EMA的差值计算A1，再用加权平滑得到B1。当A1≥B1时显示为多头走势（紫色线），当A1<B1时显示为空头走势（橙色线）。 2. **RSI强弱部分**：计算从1天到21天共20个不同周期的RSI值，然后取前5个周期的平均值作为"短线RSI"，取后15个周期的平均值作为"中线RSI"。这种设计相当于同时观察短期和中期市场强弱状态。
买卖信号
1. **买入信号A**：短线RSI上穿中线RSI（金叉），表示短期多头力量增强 2. **买入信号B**：选股公式中，B1>REF(B1,1) AND CROSS(B1,0)，即B1保持上升且突破0轴 3. **卖出信号**：中线RSI上穿短线RSI（死叉），表示短期多头力量减弱
用法
1. **趋势判断**：观察紫色"短线做多"线和橙色"短线做空"线的位置关系，在0轴上方运行表示多头趋势，下方表示空头趋势 2. **RSI金叉死叉**：当短线RSI（白线）上穿中线RSI（黄线）时买入，下穿时卖出 3. **B1颜色提示**：红色柱表示B1下跌且为负，黄色柱表示B1上涨且为负，绿色柱表示B1下跌且为正 4. **选股应用**：可选出B1由负转正且持续上升的股票
