买卖信号

**买入信号**：当"启爆"条件满足时（即XA_23 AND XA_21为真），指标会绘制蓝色柱状线（STICKLINE）作为买入信号。 **信号触发条件**： 1. **XA_21（核心条件）**： - **XA_7**：2天前跌幅>3%且均线多头排列 + 昨天上影线阴线（最高价<2天前开盘价）+ 今天阳线涨幅>3.1%且均线多头排列 + 昨天成交量萎缩 - **XA_8**：2天前跌幅>4.1%且均线多头排列 + 昨天阳线（最高价<2天前开盘价，涨幅<1.5%）+ 今天阳线涨幅>3.1%且均线多头排列 + 昨天成交量萎缩 - **XA_14**、**XA_19**：与XA_7/XA_8类似，但分别针对3天前和4天前的形态 2. **XA_23**：最近30天内出现过涨停（收盘价/前收盘价>1.095且最高价=收盘价），且前2天也满足这个条件 **总结**：这是一个"启爆"选股指标，寻找前期连续下跌后出现特定K线组合（缩量反弹、均线多头排列），且近期有涨停记录的股票。

用法
