我一直在尝试从 WSE（华沙证券交易所）完成几只股票的当前数据。我专注于 stooq，因为雅虎不涉及波兰股市。
一旦我尝试了 pandas-datareader for stooq 的代码，我看到以下错误：
"StooqDailyReader request returned no data;
check URL for invalid inputs: https://stooq.com/q/d/l/"
在此链接下，csv 文件告诉我提供的股票代码错误，但相同的股票代码直接在 stooq 网站上运行良好。你知道那里可能有什么问题吗？
import pandas_datareader.data as web
prices = web.DataReader('KGH', 'stooq')
print(prices)
你想要这样的东西吗？
import quandl
mydata = quandl.get("WSE/WIG20TR")
print(mydata)
那，产生以下。
