小编给大家分享一下如何利用Joinquant数据源为vnpy添加期货行情数据，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
使用聚宽(Joinquant)数据源JQData为vnpy添加期货行情数据
代码就两个文件，一个config.json主要放登陆用户名和期货品种名称对应表，因为期货品种在聚宽的名称是不一样的。
JQDataload.py是提供分钟级别下载方法，和一个期货品种名称对照列表从聚宽下载。
聚宽一天提供100万条数据下载，所以每次下载结束会有倒计时提供。其实代码很简单，唯一难点就是就是vnpy是每天9点00开始点，而聚宽是每天9点01为开始点；就抄抄之前vnpy已有代码解决。
结构如下
-JDDataService
|--config.json
|--JQDataload.py
其实使用很简单，步骤如下：
1.运行 pip install jqdatasdk ， 安装jqdata的sdk
2.在聚宽平台注册试用数据，链接： /tupian/20230522/404 "Username": "聚宽申请", "Password": "聚宽申请", "rb1910":"RB1910.XSGE", "zn1807": "ZN1807.XSGE", "rb0000": "RB9999.XSGE" }
JQDataload.py代码如下：
