Capital, Dunn will show you , but you need $10 million in the account.
You might peruse collective2.com they might have some futures traders, though its probably all daytrading eminis. And the real risk of this stuff should have you running the other way.
The only way might be finding a good backtesting platform for futures. Trading recipes or the like. Not too sure myself. I only test a continuous contract at a time, and I have a hard time beating the index with my current stuff Im putting together.
