买卖信号

1. **循环低位**：(((KDJ.J < 5) AND (A21 < 20)) AND (A23 < -5)) AND (KDJ.D < 20) - KDJ的J值小于5，D值小于20，且A21<20，DMA指标A23<-5 2. **中底**：(A24 < -18) AND (A21 < 20) AND (KDJ.K < 18) - 价格相对13日成本均线<-18%，且K<20，J<18 3. **大底**：(A24 < -24) AND (A21 < 20) AND (KDJ.D < 20) - 价格相对13日成本均线<-24%，且D<20 4. **绝底**：(A24 < -30) AND (A21 < 15) AND (KDJ.D < 15) - 价格相对13日成本均线<-30%，且D<15，K<15 5. **红色粗柱子**（放量上涨信号）：成交量异常放大且股价上涨

用法

- 本指标主要用于判断市场超卖和底部区域 - 信号级别从弱到强依次为：循环低位 → 中底 → 大底 → 绝底 - 绝底信号是最强的买入信号，表示价格严重超卖 - 配合红色粗柱子信号可增强买入确定性 - 适用于中长期底部判断，建议结合其他技术分析方法验证 - 100和-100为CCI指标的常规超买超卖边界
