Futures are very volatile. It's not unusual to see large gains when trading them. While their use of options offsets some of the high risk, many times the options are illiquid and can't stop a margin call.
In this case, the company utilized an average of 27% of its equity. That's about $4000. So the returns are based on playing with $4000. That's not going to get you very many contracts.
In order to test a system, a significant deposit must be made, especially with the new higher margins that have been imposed by the exchanges.
But if you're so great at flipping futures contracts, best bet would be to take $150,000 and trade an account rather than spend $150,000 for a shell. I believe they think there's more money in selling stock than their trading system, hence we are here.
