Stock Market Data

[dr.silly]

I'm interested in doing some hypothetical stock market-ing with a little bit of programming. The only problem is, where can I get stock market data for my program. A little googling hasn't revealed anything, so I'm wondering if anyone knows of free electronic stock market information?

Yahoo finance

You may refer the source code of JStock - Free Stock Market Software (http://jstock.sourceforge.net) to see how to programmatic retrieve data from Yahoo! Finance. It is written in Java.

If you are using C#, another good resources is http://code.google.com/p/yahoo-finance-managed/

I'm curious what people think about these compared to Qtstalker?

My goal is to gather historical data, I do not want to have to have the code running all day, and want to be able to snapshot the past of new stocks as my models change.

Thoughts?

I just recently got into trying to pick stocks using a python program. I know you can get historical data using yahoo.
