概述

工欲善其事, 必先利其器. 想做量化, 数据是基本! 本篇我们会介绍如何获取数据.

数据接口种类

• 获取指定行业, 板块股票列表
• history_bars: 指定股票合约历史数据
• get_fundamentals: 查询财务数据

行业 & 板块 股票类表

股票代码 & 代码补齐

RiceQuant 上的股票

上证:

深证:

股票自动搜索及补全

• Windows 用户: 输入 ctrl + i
• Mac 用户: 输入 command + i

当我们输入了这个组合键之后, RiceQuant 在线 IDE 就会进入代码搜索和自动完成模式.

接着我们可以输入任何一种进行搜索和自动补全.

• 股票数字代码: 自动补全为股票数字代码, 比如 “000001.XSHE”
• 股票中文全称: 自动补全为股票中文全称, 比如 “贵州茅台”
• 股票拼音缩写: 自动补全为股票中文全称, 因为股票拼音缩写并不是独一无二的, 比如 ZSDC 补全为 “招商地产”

获取行业

获取某行业股票数据, 代码如下:

industry (code)

返回:

属于该行业的股票 order_book_id 或 order_book_id list.

范例:

[In]
industry('A01')
[Out]
['600540.XSHG', '600371.XSHG', '600359.XSHG', '600506.XSHG',...]
[In]
industry(industry_code.A01)
[Out]
['600540.XSHG', '600371.XSHG', '600359.XSHG', '600506.XSHG',...]

获取板块

获取某板块股票列表, 代码如下:

sector(code, market='cn')

返回:

属于该板块的股票 order_book_id 或 order_book_id list.

范例:

[In]sector('Energy')
[Out]
['300023.XSHE', '000571.XSHE', '600997.XSHG', '601798.XSHG', '603568.XSHG', .....]
[In]sector(sector_code.Energy)
[Out]
['300023.XSHE', '000571.XSHE', '600997.XSHG', '601798.XSHG', '603568.XSHG', .....]

支持的行业如下, 想要了解全球行业标准划分标准参考全球行业标准分类:

获取股票合约数据

某一合约历史数据

history_bars(order_book_id, bar_count, frequency, fields=None, skip_suspended=True, include_now=False)

获取指定合约的历史行情, 同时支持日以及分钟历史数据. 不能再 init 中调用.

参数:

通过 bar_dict 获取

bar_dict 对象也可以获取行情数据: 只能获取当前运行日期的, 不能获取之前日期.

Bar 对象

范例:

logger.info(bar_dict[context.s1].close)

获取财务数据

查询财务数据

get_fundamentals - 查询财务数据

get_fundamentals(query, entry_date, interval=None, report_quarter=False, expect_df=False)

获取历史财务数据表格. 目前支持中国市场超过 400 个指标, 具体请参考财务数据文档 . 目前仅支持中国市场. 需要注意, 在 RiceQuant 上查询基本面数据时, 我们是以所有年报的发布日期 (announcement date) 为准, 因为只有财报发布后才成为市场上公开可以获取的数据.

参数:

参数	类型	说明
query	SQLAlchemyQueryObject	SQLAlchemy 的 Query 对象。其中可在’query’内填写需要查询的指标，'filter’内填写数据过滤条件。具体可参考 sqlalchemy’s query documentation 学习使用更多的方便的查询语句。从数据科学家的观点来看，sqlalchemy 的使用比 sql 更加简单和强大
entry_date	str, datetime.date, datetime.datetime, pandasTimestamp	查询财务数据的基准开始日期
interval	str	查询财务数据的间隔。例如，填写’5y’，则代表从 entry_date 开始（包括 entry_date）回溯 5 年，返回数据时间以年为间隔。‘d’ - 天，‘w’ - 周，‘m’ - 月， ‘q’ - 季，‘y’ - 年
report_quarter	bool	是否显示报告期，默认为不显示。‘Q1’ - 一季报，‘Q2’ - 半年报，‘Q3’ - 三季报，‘Q4’ - 年报
expect_df	boolean	默认返回原有的 Panel 数据结构。如果调为真，则返回 pandas dataframe

返回
pandas DataPanel - 财务数据查询结果.

范例

[In]
dp = get_fundamentals(query(fundamentals.eod_derivative_indicator.pe_ratio).filter(fundamentals.stockcode == '000001.XSHE'), '2016-08-01','4q' ,report_quarter = True)
[In]
dp.minor_xs('000001.XSHE')
[Out]report_quarter	pe_ratio
2016-08-01	2016-Q1 	7.0768
2016-04-29	2016-Q1		6.7755
2016-01-29	2015-Q3		6.5492
2015-10-29	2015-Q3		7.3809

过滤指标条件

• query().filter: 过滤大小
• query().order_by: 排序
• query.limit(): 限制数量
• fundamentals.stockcode.in_(): 在指定股票池当中过滤

案例:

q = query(fundamentals.eod_derivative_indicator.pe_ratio,  # 获取市盈率fundamentals.eod_derivative_indicator.pcf_ratio  # 获取市现率 ).filter(fundamentals.eod_derivative_indicator.pe_ratio > 20,  # 过滤市盈率大于20fundamentals.eod_derivative_indicator.pcf_ratio < 50  # 过滤市现率小于50).order_by(fundamentals.eod_derivative_indicator.pe_ratio # 用盈率排序, 从小到大).limit(10)  # 取10个

定时获取数据

每天运行

scheduler.run_daily

scheduler.run_daily(function)

参数:

参数	类型	注释
function	function	使传入的function每日运行。注意，function 函数一定要包含（并且只能包含）context, bar_dict 两个输入参数

每周运行

scheduler.run_weekly

scheduler.run_weekly(function, weekday=x, tradingday=t)

注意:

• tradingday 中的负数表示倒数
• tradingday 表示交易日. 如某周只有四个交易日, 则此周的tradingday=4 与 tradingday=-1 表示同一天
• weekday 和 tradingday 不能同时使用

每月运行

scheduler.run_monthly

scheduler.run_monthly(function, tradingday=t)

注意:

• tradingday 中的负数表示倒数
• tradingday 表示交易日. 如某周只有四个交易日, 则此周的tradingday=4 与 tradingday=-1 表示同一天

运行顺序

如果我们设定了一个按月运行: scheduler.run_monthly(get_data, tradingday=1). 假设是 2021年 3 月份, 3 月 1 号是第一个交易日:

• 3 月 1 号: before_trading -> get_data -> handle_bar
• 3 月的其他日期: before_trading -> handle_bar
