3.2 尾盘竞价与收盘价的意义
## 尾盘竞价与收盘价的意义 **尾盘集合竞价**（14:57-15:00）和开盘集合竞价规则类似，但更为关键，因为它决定了当天的**收盘价**。 ### 尾盘竞价规则 | 时段 | 说明 | |------|------| | 14:57 - 15:00 | 集合竞价阶段，**不能撤单** | | 15:00 | 确定收盘价，当日交易结束 | ### 收盘价的重要性 - 收盘价是第二天**开盘参考价**的基础 - 涨跌幅计算基准（今日收盘 vs 昨日收盘） - 指数成分股权重计算、ETF净值计算均以收盘价为准 - **主力拉升尾盘**：部分资金会在尾盘竞价阶段拉升股价，制造涨停或强势收盘，吸引隔日追涨 ### 尾盘操作注意事项 - 14:55之前如果想撤单，一定要在进入尾盘集合竞价**之前**操作完毕 - 临近收盘大单涌入，往往是主力在**建仓或出货**，需结合当天走势判断 - 新手一般不建议在尾盘追高，因为无法确认次日走势
