Quotetracker is free (2 days intraday charts, plus daily charts). For intra-day, you still must provide a data feed (free feeds are available for daily charts). Go to quotetracker.com web site to see which brokers they will work with (almost all well-known brokers) for a data feed, or you can get a subscription data feed for about $10 a month (but that would not include real time futures, for that you have to pay more.)
