Here is a list of free intraday data providers:
Does anybody know where I can get free historical intraday stock data? I'd like to try to get 15 minute interval data for a new model I am working on. Alternative, if somebody has this data available already, I would much appreciate it if you were willing to share.
I thought I would post an update to my original post so perhaps this can help others in the future.
First, comprehensive free historical intraday stock data doesn't exist unless you are a student. If you are a student though, see if you can access the Wharton Research Database Services (WRDS) which has comprehensive historical data in tick resolution. I had access to this, but decided not to use it because it takes quite a bit of time/coding to process it into a more useable format.
