free data feed?

[italiano40]

I would like to do some testing with a free data feed so i can tweak my system, if it has a java API that would be good, but not necessary thank you

There are brokers that offer Zenfire (java API) Initial deposit required, but no monthly charges. Oh, and no historical data so might not be what you are looking for.

You will need an account, but IB is a good choice for lost cost data.

IB is limited to 100 tickers at once. And it's not real tick-data.

that plus they only broadcast quotes every 100ms so if you code it right you can get 12-ticks per second (open 1-sec bar, close 1-sec bar, 10x 100ms intervals). Thats not really tick level data.

EDIT: I don't know of anything for free that's decent. Tick data = you get what you pay for.

IB is based on snapshot quotes. But when you want free, you can't be picky.
