persistent caching

[hajes]

hi guys,
I am using yfinance for years in my investing career. Option screener, stock valuations. I started to experiment with caching as suggested in documentation. It is great for testing. It seems to store all data fetched from Yahoo...well at least for an hour or so.

In previous attempts, I simply stored all in pandas/sqlite3. Update only what is needed without fetching all data again.

I came across yfinance-cache clone. It doesn't work with historical data. It makes me wonder one can setup longer period of caching. Let's say 1 month of data cached. I run the script once a week, and wish to avoid fetching all over again.

Any suggestions, please?
