Free Real-Time NASDAQ Quotes

I used to watch the financial markets throughout the day via CNN Money, until most pages force-fed me streaming video that I have to pause/stop manually. That caused me to switch to Yahoo! Finance.

Google Finance will be my new home since they have begun to provide real-time stock quotes for NASDAQ securities. I have become quite the fan of Google products, not because I'm a fan of Google, but because they just make quality products: GMail, Google Reader, Google Calender, Google Maps, Google Code, Google Code Search, and - of course - Google Search.

I haven't tried it myself, but I've heard that Google's SketchUp is quite handy.

New Project

I've started creating a R API to the opentick data servers. My goal is to provide a native R interface to opentick real time and historical market data. I have reservations about being able to make it solely R-based, due to threading issues I don't totally understand at the moment.

Even though I've read of quality issues with opentick's data, the price can't be beat for small, part-time traders (i.e. me).

Due to the upgrading of its network infrastructure, opentick is not currently accepting new users. That should change in the near future, however. You can sign up to be notified when the upgrades are complete.

For those who already have accounts with opentick, you can find the very-alpha source code on r-forge.
