TradingView A股增强指标
涨停、炸板、连板与缺口
一张图看清
在 TradingView 上查看 A 股行情时，K 线本身可以呈现价格变化，但涨停、跌停、炸板、连板等具有 A 股市场特点的信息，往往还需要投资者自己识别和整理。
为减少这些重复判断，我制作了一个 TradingView A股增强指标。它不预测行情，也不提供买卖信号，而是把看盘时常用的客观信息直接整理到图表上，让涨跌停事件、连板情况、未回补缺口以及当前周期数据更加直观。
涨停、跌停与开板事件直接标记
指标会对涨停和跌停 K 线进行颜色区分，同时在图表上显示相应的事件标签。
当股票盘中最高价触及涨停价，并且收盘仍然封在涨停价时，图表会将其标记为“涨停”；如果盘中触及涨停价，但收盘没有封住，则会标记为“炸板”。
跌停采用相同的判断方式：收盘封在跌停价时标记为“跌停”，盘中触及跌停后又打开则标记为“翘板”。如果当天的开盘价、最高价、最低价和收盘价全部处于涨停价，还会单独识别为“一字涨停”。
这些标签并不是额外的行情判断，而是把原本隐藏在价格数据中的事件直接显示出来，查看历史走势时不必再逐根 K 线核对。
自动适配不同板块的涨跌幅规则
A 股不同板块的涨跌幅限制并不完全相同。指标会根据股票所属市场自动应用相应规则：
- 主板通常按 10% 处理；
- 创业板和科创板通常按 20% 处理；
- 北京证券交易所通常按 30% 处理。
切换股票时不需要手动修改参数，指标会自动重新判断相应的涨跌停价格。
分钟图只保留当天第一次封板位置
在分钟周期中，一只股票封板后，后续可能有几十根 K 线都收在涨停价。如果每根 K 线都显示“涨停”标签，画面很快就会被重复信息占满。
因此，分钟图采用了单独的显示逻辑：每个交易日只标记第一次收盘达到涨停价的 K 线，跌停也采用同样的处理方式。
这样既能看到当天第一次真正收盘封板的位置，也能避免大量重复标签影响图表阅读。
自动显示连续涨停板数
在日线周期中，如果股票连续多个交易日涨停，指标会自动连接这一段行情，并显示当前连板数量。
连续两个涨停显示为“2板”，连续三个涨停显示为“3板”，更高的连板也会继续累计。这个功能不对连板行情作强弱评价，只是把原本需要手动计算的信息直接呈现在图表上。
标出尚未回补的跳空缺口
当当天开盘价直接跳过前一交易日的最高价时，两者之间会形成向上跳空缺口；向下跳空则采用对应的判断逻辑。
指标会把这些缺口区域绘制在图表上，并持续保留尚未回补的部分，方便观察价格后续是否重新进入缺口区域。
随图表周期变化的信息面板
图表右上角还提供了一个简洁的信息面板，显示：
- 当前周期与时间；
- 开盘价、收盘价、最高价和最低价；
- 涨跌幅与振幅；
- 成交量与估算成交额。
面板数据会跟随图表周期变化。在 30 分钟图中，它显示当前 30 分钟 K 线的数据；切换到日线后显示日线数据；切换到周线后，则显示当前周的数据。
使用时需要了解的限制
这个指标以 TradingView 和 Pine 能够获得的数据为基础，因此有两个边界需要提前说明。
第一，Pine 无法获得一只股票在每个历史交易日真实、完整的 ST 状态。如果某只股票历史上曾经被 ST，之后又摘帽，部分历史区间的涨跌停识别可能存在误差。
第二，新股上市初期可能存在不设涨跌幅限制的特殊交易阶段，当前版本没有自动处理这些阶段。查看新股上市初期行情时，需要结合实际交易规则自行确认。
让图表负责整理信息，而不是替代判断
这个 A 股增强指标的定位很明确：不预测涨跌，不生成买卖信号，也不替代交易决策。它所做的，是把涨停、跌停、炸板、翘板、连板、缺口和周期数据等客观信息统一整理到图表上。
打开图表后，常用信息能够更快被识别；切换股票和周期时，也不需要反复进行相同的手动判断。对于经常使用 TradingView 查看 A 股行情的用户，它可以让图表更贴近 A 股市场的实际看盘习惯。
