下载历史行情数据

download_history_data(stock_code, period, start_time='', end_time='')

1

• 释义

• 补充历史行情数据

• 参数

• stock_code - string 合约代码

• period - string 周期

• start_time - string 起始时间

• end_time - string 结束时间

• 返回

• 无

• 备注

• 同步执行，补充数据完成后返回

下载数据实操：

from xtquant import xtdata
code ='600050.SH'
period = '1m'
day = '20221220'
xtdata.download_history_data(stock_code=code, period=period, start_time=day, end_time=day)

检验下载结果：

在\userdata_mini\datadir目录中，根据不同市场去找SH或SZ子目录，继续去60目录（1m周期）就能看到新下载的600050.DAT文件了

本地文件读取历史行情

请参考 [QMT]08-从本地行情数据解析历史K线信息

from xtquant import xtdata
import pandas as pd
import datetime,time
code =['600050.SH']
period = '1m'
day = '20221220'
data_dir=r'X:\iQuant\userdata_mini\datadir'
kline_data=xtdata.get_local_data(field_list=[],stock_code=code,period=period, start_time=day,end_time=day,count=10,data_dir=data_dir)
df =pd.concat([kline_data[i].T for i in ['time', 'open', 'high','low','close','volume','amount','settelementPrice', 'openInterest']],axis=1)
df.columns=['time','open','high','low','close','volume','amount','settelementPrice','openInterest']
df['time']=df['time'].apply(lambda x: datetime.datetime.fromtimestamp(x/1000.0))
print(tabulate(df,headers=df.columns,))
print(df.shape[0])

读取结果：

time open high low close volume amount settelementPrice openInterest
