核心逻辑
这是一个综合型**超跌反弹/抄底指标**，包含8个独立的底部信号模块。核心原理是：通过多维度条件筛选严重超跌的股票，等待反弹机会。 主要筛选维度包括： 1. **成交量萎缩**：换手率极低或近期缩量 2. **价格超跌**：收盘价较近期高点跌幅较大，接近阶段低点 3. **成本分析**：股价远离成本密集区 4. **技术面超卖**：MACD、DIF等技术指标处于超卖状态 5. **波动特征**：近期有明显的上下影线波动
买卖信号
**买入信号（8个）：** | 信号名称 | 触发条件 | 位置 | |---------|---------|-----| | 抓大底 | 成交量萎缩 + 股价涨幅>3%未涨停 + 成本/价格比>1.3 | 0.2 | | 极品底 | 股价<成本5% + MACD<15 + 操盘线从低位回升 | 0.4 | | 底部买入 | 价格DMA超跌<-8% + 指数均线<23 + 大盘配合 | 0.7 | | 底部来临 | 成交额/成交量异常 + KDJ的K值上穿20 | 0.8 | | 妖底 | 满足选股条件且出现波段信号 | 0.1 | | 核心低点 | 多重价格条件：开盘价低+收盘价低+成本5%压制+波动>5% | 无标注 | | 抄底三代 | 缩量 + 涨幅>2.5% + 均线条件 | 无标注 | | 春笋 | DIF<-100 + DEA>13 + 差值放大 + 股价>成本5% | 无标注 | **无明确卖出信号**（该指标专注于抄底买入）
用法
1. **组合使用**：该指标包含多个底部信号，可综合判断。当多个信号同时出现时，成功率更高 2. **单兵作战**：每个
