Yahoo Finance widget will not load data

[chrislee35]

current yfinance version 0.2.52 API no longer has yf.pdr_override(). I can work around this issue by pinning version yfinance==0.2.38.
Please update orangecontrib/timeseries/datasources.py to use the new API.

Replace

    yf.pdr_override()
    f = pdr.get_data_yahoo(symbol, since, until)

With

  dat = yf.Ticker(symbol)
  dat.history(start=since, end=until)

There are 2 new columns, and it dropped the Adj Close column.
