买卖信号
1. **买入信号（金叉）**：`DRAWICON(FILTER(CROSS(K,D) AND K<50,1),0,1)` - K、D金叉且K<50时显示买入图标 2. **买入信号（超卖）**：`DRAWTEXT(CROSS(J,(0-5)),(0-4),'吸'),COLORCYAN` - J线从下方穿越-5，显示"吸"字 3. **卖出信号（死叉）**：`DRAWTEXT(CROSS(90,J),105,'抛'),COLORGREEN` - J线从上方穿越90，显示"抛"字 4. **超买信号**：`STICKLINE(CROSS(长D,80),108,115,4,0),COLOR33FF33` - 长周期D线穿越80 5. **超卖信号**：`STICKLINE(CROSS(长D,15),0,10,4,0),COLOR3333AA` - 长周期D线穿越15 6. **底背离**：`DRAWTEXT(FILTER(BB2>0,5),-8,'底背离'),COLORYELLOW` - KDJ底背离信号 7. **顶背离**：`DRAWTEXT(FILTER(DD2>0,5),-8,'顶背离'),COLORGREEN` - KDJ顶背离信号
用法
1. **适用场景**：短线交易，结合MACD指标辅助判断 2. **参数调整**：系数N默认1000，可根据股价高低调整（公式注释：可根据股价调整N，默认1000） 3. **买入时机**：K、D金叉且K<50时关注；J线超卖（穿-5）时考虑买入；出现底背离时是较强的买入信号 4. **卖出时机**：J线超买（穿90）时考虑卖出；出现顶背离时是较强的卖出信号 5. **注意事项**：该指标包含短周期KDJ（9日）和长周期KDJ（90日），可结合使用；MACD作为辅助判断；包含背离信号，需结合股价走势综合判断 6. **图形说明**：红色柱子表示MACD>0，黄色柱子表示MACD下跌但仍>0，绿色柱子表示MACD<0且下跌
