Some Feedback about yfinance-cache HOT 1 CLOSED

Data isn't cached in one homogenous block that is rendered 100% obsolete and refetched. Instead think like a database.

Price data is easy. Tool records when data fetched, and market trading hours are public knowledge, so can calculate what and when to fetch.

Financials update not implemented yet, but should be simple (I already do this in prototype code). Balance sheet etc tables give me earnings release interval. earnings_dates gives me release dates (for most tickers). So can predict when next earning release is, and usually by then Yahoo has a concrete date so know exactly when to fetch new financials.

But before financials update is implemented, first it needs to be fixed in yfinance - many issues of yfinance retuning different data than website, and a proposed PR fixes this. Maybe after then the "different yields" issues disappears.
