http://commodityrobot.com/ is a SCAM. You can pay for their Expert Advisor using clickbetter.com, so you have guaranteed possibility to return money in 60 days if you wish. Problem is that EA will make you profit during these 60 days, and after expiration of money return date - EA will stop to make profit, and will make horrible trades, with intention to empty your balance.
Basically you can buy their EA, make some profit, stop autotrade and request money return before end of 60 days, and also withdraw money from broker (EA is locked to myfxchoice broker to single account). Sort of win.
I think its required to request return and stop trading already after 30 days, because only first 30 days were really profitable for me. But all this is just gambling, they can empty your account even faster if they want.
