If you have an IB account this is by far the best I have seen www.futures-trader.net Make 'em pretty, Chris P.S. For simulation it is free.
www.mocktrading.com but something is fishy with the stops and limit orders.... seems like i get filled immediatly when i enter a stop even if the market isnt trading in that range.. and i get exact fills on my stop price instantly..
And the quotes are RT? I guess not, perhaps I am wrong, but I once looked into that and got discouraged. I guess it was because the quotes were delayed and since my charts were RT trading this way was just plainly stupid. Maybe this was not that, so correct me if I am wrong.
