python pandas处理股票量化数据：笔记4

更新日线数据到最新日期，下面是深发展（平安银行）更新到20240715以后的stock_daily表。因为积分不够，无法下载tushare.pro接口的通用复权行情数据，只能使用旧的日线数据接口pro.daily，下载的数据没有日线复权因子和均线数据。

tushare通用行情接口pro_bar整合了股票（未复权、前复权、后复权）、指数、数字货币、ETF基金、期货、期权的行情数据，未来还将整合包括外汇在内的所有交易行情数据，同时提供分钟数据。不同数据对应不同的积分要求，积分不够不能使用pro_bar接口：Tushare数据

#均线
df = ts.pro_bar(ts_code='000001.SZ', start_date='20180101', end_date='20181011', ma=[5, 20, 50])
注：Tushare pro_bar接口的均价和均量数据是动态计算，想要获取某个时间段的均线，必须要设置start_date日期大于最大均线的日期数，然后自行截取想要日期段。例如，想要获取20190801开始的3日均线，必须设置start_date='20190729'，然后剔除20190801之前的日期记录。#换手率tor，量比vr
df = ts.pro_bar(ts_code='000001.SZ', start_date='20180101', end_date='20181011', factors=['tor', 'vr'])对于pro_api参数，如果在一开始就通过 ts.set_token('xxxx') 设置过token的情况，这个参数就不是必需的。
例如：
df = ts.pro_bar(ts_code='000001.SH', asset='I', start_date='20180101', end_date='20181011')
