# 二板日历接口文档
|
||||
|
||||
## 1. 基本信息
|
||||
|
||||
- 接口名称:二板日历
|
||||
- 请求方法:`GET`
|
||||
- 请求路径:`/api/v1/limit-board/second-cal`
|
||||
- 接口用途:按交易日统计每日二板数量、二板封板数量、二板炸板数量,以及二板股票 T+1 盘中盈利概率。
|
||||
|
||||
## 2. 请求参数
|
||||
|
||||
| 参数 | 类型 | 必填 | 默认值 | 说明 |
|
||||
| --- | --- | --- | --- | --- |
|
||||
| `tradeStartDate` | `string` | 是 | 无 | T 日起始日期,格式 `YYYY-MM-DD` |
|
||||
| `tradeEndDate` | `string` | 是 | 无 | T 日结束日期,格式 `YYYY-MM-DD` |
|
||||
|
||||
兼容 `start_date`、`end_date` 作为日期参数别名。
|
||||
|
||||
请求示例:
|
||||
|
||||
```http
|
||||
GET /api/v1/limit-board/second-cal?tradeStartDate=2026-05-07&tradeEndDate=2026-05-11
|
||||
```
|
||||
|
||||
## 3. 统计规则
|
||||
|
||||
- 以 `trade_calendar` 中 `exchange = 'SSE'` 且 `is_open = 1` 的记录推导 T-2、T-1、T、T+1 交易日。
|
||||
- T-1 涨停样本来自 `limit_list_d`,条件为 `limit = 'U'`。
|
||||
- T-2 同一股票不能在 `limit_list_d` 中存在 `limit = 'U'` 的记录。
|
||||
- 股票所属板块和行业来自 `stock_basic.market`、`stock_basic.industry`。
|
||||
- T 日行情来自 `stock_daily`,当 T 日最高价 `high` 触及按 T-1 收盘价和板块涨跌幅规则计算的涨停价时,计为二板。
|
||||
- 涨停价比例按板块计算:北交所 30%,创业板/科创板 20%,其余名称包含 ST 的股票 5%,其他股票 10%。
|
||||
- T 日 `close` 与 `high` 一致时,计为二板封板,`status = "limit"`。
|
||||
- T 日 `close` 小于 `high` 时,计为二板炸板,`status = "break"`。
|
||||
- T+1 盘中盈利统一按 `T+1 high > T high` 判断,概率分母只统计具备 T 日最高价和 T+1 最高价的数据。
|
