核心逻辑
该指标是一个综合型超跌反弹选股指标，主要包含两个选股逻辑： 1. **超跌反弹信号**：基于改进的MACD类指标（X_7/X_8），计算股价在55日周期内的相对位置，当该指标从超卖区域（0-11）上穿时产生买入信号，共5个级别的反弹信号（0-3-6-11）。 2. **强势股回调买入**：通过"双倍阴"形态识别强势股回调后的买入机会，要求前2-4日连续小阴小阳（振幅<5%），今日涨幅>6%且股价上涨收阳，同时满足前期连续下跌、成交量萎缩等条件。 辅助筛选条件包括：大阳线过滤（涨幅5.8%-9.8%）、趋势确认（3日内涨幅>5%）、以及多项技术面过滤（涨幅<30%、量能<5日均量3.5倍、89日内涨幅<80%等）。
买卖信号
**买入信号**： - X_9：X_8指标从11以下上穿11，且收盘价低于中轨 - X_10：X_8从11以下上穿11（处于6-11区间） - X_11：X_8从6以下上穿6（处于3-6区间） - X_12：X_8从3以下上穿3（处于1-3区间） - X_13：X_8从1以下上穿1（处于0-1区间） - X_14：X_8从0以下上穿0 - X_45：满足"双倍阴"形态条件（前期连续小阴小阳后今日大阳突破），且同时满足超跌反弹信号或X_9条件
