Hi, I wish to insert daily stock market information (brief summary) on my website.

For example:
Nasdaq 1990.12 +2.01

Is there a way to get these informaiton from other source (maybe yahoo) and display it on my website and update automatically?

Thanks in advance.

I don't know where you'd get information directly. But here's some free stock tickers and things you can use:

You can normally pick these up as simple a href links (supplied by those who feed the news).
These links are usually configurable I.E you can tell it how many articles and summary's you want.
