Thanks for helpful reply. I should choose roughly 300 (at most 500) good equities, for my personal logic. (Not interested in option/future+commodity+else) Possibly some of them are SnP500. I wonder if BATS is related to my good(???) 500 equities.
For the option/future traders, it is worth to pay substantial amount for the feed. However I am strictly equity trader who has a trading logic with 5-min or possibly 15-min.
Wrong. $15 *12 (months) * 50 (years) = 9K. If you make every month $100 profit you will have net 51K profits after 50 years. What are you waiting for?
The above link https://help.yahoo.com/kb/finance/SLN2310.html?impressions=true might be my best choice, in my personal situation for my trading logic.

Thanks. But there is some possibility in Excel MACRO that may have hidden contents. Most traders prefer clear program (with NO MACRO), such as free R or Python
you can get free" real-time data would be if you have a brokerage account with a broker that provides the data at no cost to the client. TD Ameritrade and E*Trade do for example. TDA has an API available. You can use the broker's own tools to display the data, or you can get Medved Trader for it: http://www.medvedtrader.com right now we don't have an API, but will in the future, which will allow you to access any data that MT has access to, via MT's API, thus avoiding the need to write to different APIs or situations where an API is not available
You do NOT have to provide API. Every(?) broker provides web-trading. If you do, we can use Selenium to access your webpage easily.
