Just thinking aloud...

The reasons why I never stored price data was because it used up huge amounts of storage (by old standards) and because it was easy enough to download when needed. Both changed, storage is now cheap and plentiful and Yahoo, the best source of data in times gone by, is now crappy.

Twenty years of daily price history uses about 350 to 375 kilobytes. The S&P 500 would need less than 200 MB. My web server has 10 GB. Free downloading up to a year's worth of prices is available from various sources. Instead of downloading all the data over and over again, one could just download daily or weekly prices and update the files. The only difficulty is adjusting prices for splits and dividends.

Enough thinking for one day...
