买卖信号

**买入信号：** 1. 低吸：`CROSS(A4,14) OR A5>REF(A5,1) AND CROSS(K,A2) AND K<40`（条件满足时输出10） 2. WWW条件：`SJ<20`（条件满足时输出0-20） 3. 二次金叉：`A8<15 AND D<50 AND K>REF(K,A8+1) AND CROSS(K,D) AND A5<60` 4. 图标信号：`CROSS(A3,-300) AND K<10`（显示买入图标） 5. 底背离：`二次金叉 AND A9`（显示"底背离"文字提示） **卖出信号：** 1. `A2>80 AND CROSS(95,K)`（输出85-100） 2. 无限风光：`A2>85 AND K>85 OR A2>90 OR K>90`（超买信号，显示黄色柱子） 3. 跌幅较大：`K<5 AND LLV(C,3)/HHV(C,20)<0.8`（显示绿色柱子）

用法

1. **适用场景**：该指标为综合型指标，结合了K、D、J线（A2、K、D等），适用于中短线交易 2. **主要信号**： - 当出现"低吸"条件时，可能是买入时机 - 二次金叉且底背离信号出现时，是较强的买入提示 - K、D、J线在低位形成金叉是买入信号 - 当A2或K值超过85-90时，表示进入超买区域，注意风险 - 跌幅较大信号出现时，表示股价可能已经超跌 3. **注意事项
