I have a friend who would like to get intraday data, either delayed or at the end of the day. He wants to be able to look at minute charts to review volume, and chart patterns, along with his daily charts. Is there someplace he could get this free or cheap? I told him to look into Ninja trader and Opentick, but Opentick is down or soemthing he said when he went to sign up. Any other thoughts? Thanks
