Historial Data Feeds

If you've got a budget in the 000's, you might try NxCore -- http://nanex.net/. They provide full feeds of NBBO/Level 2 for various markets, accessible through their API which also works for real-time quotes (which of course you'd have to learn).
 
Quote from tiagop:

Is there any service that provides historical data (prices, ratios, etc) feeds?

the question itself doesn't make any sense to me..but since you have only 2 posts-you will be forgiven this time :p

you need data for what? stocks?options? futures?currencies?cfd's?
daily?intraday?tick data?
which exchange? nyse,nasdaq,toronto,london?

iq feed is relatively inexpensive and user friendly and support a lot of third party soft

Hello,

I need data just as Gurufocus.com has for all the historical financial data of a company (stock prices, balance sheets, etc).

I'm creating a app ( http://stockding.com/ ) that could make good use of that kind of service.

I'm not sure if IQFeed is what I need for that. I've heard about Zacks Financials but I can't get any answer from them.

Thank you and sorry the bad post.
