Doesn't Rob Craig do something like this?
How I would do it - use wget to repeatedly poll the page and download it as a file, then parse the info from the file to your app.

4.0 has std/net/http.e which includes a few functions, one of which is get_url()... That will download get you the HTML from a web site in a cross platform manner directly into a euphoria sequence.

Thank you ChrisB and jeremy,
My Streaming Quotes come from a Java Program not really a webpage. Although you have to enter a webpage to get it (the java program).

Don, how do you get access to the streaming? Is it a console program? If so see std/pipeio.e

Thank you Jeremy,
I get my quotes from Scottrade.
I probably shouldn't use their name. But why should they care I'm paying enough for it.
I go to the Scottrade main page and click on streaming quotes.
That opens another window that says it's a java based option train,
Then 5 little windows open showing graphs, quickquotes etc.
I don't know how they do it or how to tap in to it.

That sounds a bit difficult to gain access to indeed. I'm at a loss for a suggestion.

If they are actually providing access via java (a Java-based API), then we could tap into this using JNI. (A JNI port that wraps Java AWT for Euphoria already exists.)

the free version lets you store 2 days worth of data. looks like others are frustrated by Scottrade:

yahoo or google might have other stock widgets that can hook you up. http://widgets.yahoo.com/search/?q=quotes&s=rating&os=any

i would use ngrep http://ngrep.sourceforge.net
as a starter to catch snapshots of the realtime
data feed to see if the data can be parsed
along the following lines;
1) open browser to data streaming page
2) open console window for ngrep
3) start ngrep data logging
ngrep -O log.data -d <your device number>
4) once you have captured enough data, you can replay
the data using ngrep
ngrep -I log.data -W byline
which will dump all packets captured to the screen
it would be very simple to parse the
data stream if it is in text format
however, if the data stream is in binary format
that's a whole new ball game
