I do not endorse trading with it, but for many types of uses, you might take a look at the Yahoo finance CSV "API." It has per-day resolution going back about 15 years or so.
- jwally 11y agoI'd take Yahoo's data with a grain of salt. Was tinkering with options prices there, and the data wasn't clean which lead to a lot of false positives (e.g. a lower strike call was selling for 1/2 of what a higher strike call sold for). Checkout TradeKing. You have to open an account to use it, but (to my knowledge) you don't have to fund it.
