I'd like to subscribe to Qcharts data, I've read that they have intraday data available for several years which would be great for backtesting. I require intraday volume for the SP Futures (full size, not eminis) from the CME. I've contacted Qcharts to ask this but I've gotten two different answers: Yes, they do have intraday data for the SP Futures and no they can only provide end of day data. Does anyone here who subscribes to Qcharts know the answer to my question? Could they call up a chart of the SP Futures symbol SP03Z and see if it has intraday volume and post the chart. I notice that Qcharts offers a referral program: http://help.lycos.com/scripts/qcharts.cfg/php.exe/enduser/std_adp.php? p_refno=030326-000000 If this program is for real I'd be glad to help someone get a free month if they could help me get a real answer to my question.
