I'm looking for data service provider that requires NO trading account (that provides at least data for the E-mini S&P). All I need is reliable real time data. The price of the service is very critical for me. Do all the companies appear here http://www.ninjatrader.com/Support.php#Help-Guides
support such service?
If not who does and which of them are the cheapest?
Thanks,
Ofir
