get_historical_price_data() error #186

Open jmalbornoz opened 3 months ago

jmalbornoz commented 3 months ago

Here's what I am trying to do:

from yahoofinancials import YahooFinancials
ticker = 'MSFT'
yahoo_financials = YahooFinancials(ticker)
data = yahoo_financials.get_historical_price_data("2024-03-01", "2024-03-26", "daily")

After a long wait of some 20 minutes I get the following error message:

TypeError Traceback (most recent call last) Cell In[4], line 1 ----> 1 data = yahoo_financials.get_historical_price_data("2024-03-01", "2024-03-26", "daily")

TypeError: 'NoneType' object is not iterable

I have tried other tickers and the result is the same.

I've been having the same issue with this code. I'm taking a Quantitative Analytics Course and am encountering this issue when trying to retrieve data with this call.

I have met the same problem.
