[commod_price] Execution takes a very long time

[mmcky]

This code cell

import yfinance as yf
import matplotlib.pyplot as plt
s = yf.download('CT=F', '2016-1-1', '2023-4-1')['Adj Close']

is taking a very long time to run (> 2minutes and still running)

For me, that ran well but didn't download, and gave the following error:

[*********************100%***********************]  1 of 1 completed

1 Failed download:
- CT=F: No timezone found, symbol may be delisted
