I ran an ES back test on a SMA Cross Over strategy. Time period is from 4/1/2007 - 8/17/2007. I know this is very narrow but it's pretty much all I had to work with. Looks like the system made over $10,000 (exluding commission charges) trading 1 contract. Largest drawdown was just at 2% for no more than a day or so. Is this too good to be true? Am I missing something? I'm attaching the results for anyone to disect. Thanks.
