Has anybody else noticed that Yahoo Finance has gone to a realtime stock model? Their pages update with AJAX in real-time:
YHOO: Summary for YAHOO INC - Yahoo! Finance (For example)
Watch the page for a bit. It doesn't seem as current or fast as my TD Ameritrade tools, but it's still fairly close, and definitely fine for just checking the latest bid and prices. Also, they have new Flash based stock graphs:
Yahoo! Finance Charts
Pretty nice if you ask me. They've come a long way in the past few months. (And they were already one of the best before that!)
