# 数据的批量完整下载方式代码 via yutiansut 看到有issue提出不知道如果下载完整的数据,关于数据位置指针的使用,给一个示例代码: ``` from pytdx.hq import TdxHq_API api=TdxHq_API() with api.connect(): data=[] for i in range(10):

0-799 800-1599 1600-2399 .... ``` 依次 然后需要注意的是 0代表的是今天的指针 ,所以 指针获取方式要翻过来写 首先是 7200-7999的数据 最后才是0-799的数据 基本上 日线级别 8000条足够覆盖了 分钟线,小时线要长一点 封装成函数 ``` from pytdx.hq import TdxHq_API api=TdxHq_API() def
