股票个人量化交易数据获取模块
Project description
数据获取
直接通过pip安装即可:
pip install -U qfetch
数据获取模块qfetch是相对独立的模块,主要功能是从公开的数据源获取数据。qfetch提供两种api,一种是异步版本,以fetch_
开头,另外一种是阻塞版本,以block_fetch_
开头。
Rust编写的模块和函数是通过qfetch.qfetch
导出,该模块原样导出Rust 封装的函数(.pyi\ 文件)。一般情况下,是不需要使用该包下面的函数,在qfetch.fetch
下面有此包的包装函数,包装函数除了可返回原始的Rust输出外,也提供可选装换为pd.Dataframe格式的参数。如:
In [1]: import qfetch as fetch
In [2]: await fetch.fetch_trade_date()
Out[2]:
trade_date
0 20120104
1 20120105
2 20120106
3 20120109
4 20120110
