我如何让外汇行情在雅虎金融工作？

Question

When I use any ticker that isn't a forex pair it works. But with the fx tickers it doesn't. I end up getting an error.

from yahoo_fin.stock_info import get_live_price
get_live_price('EURUSD=X')

Below Is the error I encountered.

     7 #stockprice = get_live_price(str(Stock))

---> 60     start = html.index('"HistoricalPriceStore"')
    61     end = html.index("firstTradeDate")
    62 

ValueError: substring not found

any ideas? It' clearly something to do with the ticker. When I use 'nflx' or 'aapl' it works like a charm. It's with forex that it seems to misbehave?

That is the same error you get if the tag is made up trash. Could you be trying to request a malformed tag/ticker?

In [12]: from yahoo_fin.stock_info import get_live_price 
    ...: get_live_price('poop') 
    ...:
