问题描述
我可以使用以下代码从Google财经获取历史数据.但是最古老的是从2016-09-20开始.这对于回测来说太短了.我需要涵盖2008年的历史数据.
I can use the following code to get historical data from Google Finance. But the oldest is from 2016-09-20. This is too short for back testing. I need historical data which covers the year of 2008.
import pandas_datareader.data as web
start = datetime.datetime(2002, 1, 1)
end = datetime.datetime(2017, 1, 27)
aapl = DataReader("AAPL", "google", start, end)
print(len(aapl))
print(aapl.head())
输出如下:

2016-09-21 34.93 37.27 34.47 37.01 37582384
2016-09-22 38.22 38.52 37.73 38.47 22289829
2016-09-23 38.24 38.58 37.90 38.12 18705969
2016-09-26 36.69 36.94 35.63 35.97 23382130
推荐答案
使用fix-yahoo-finance
,然后使用yahoo
而不是Google作为您的来源.看来Google最近已经锁定了很多数据.
Use fix-yahoo-finance
and then use yahoo
rather than Google as your source. It looks like Google has been locking down a lot of its data lately.
首先,您需要点安装 fix-yahoo-finance
.
First you'll need to pip-install fix-yahoo-finance
.
然后:
from pandas_datareader import data
import fix_yahoo_finance
aapl = data.get_data_yahoo('AAPL', start='2000-01-01')
print(aapl.head())
Open High Low Close Adj Close Volume
