May not be want you want, but you can open up a ThinkOrSwim account.....an voila, you'll have real time data, AND a really good charting and analysis tool.
They even have a paper money platform that lets you execute real time trades, with all of the functionality of the real platform. it's great to have for being free if you don't want to pony up the cash to get good charting software and a data feed.
I have a friend that has been using a paper money account for 3 months just to have access to it. He trades through another broker.
