UPDATE : In August 2010 - One Of the WORST trading months in years we made $9,291 trading just ONE contract. Yes, just ONE contract - that is over 180 points trading the ES Emini Futures! That would be $18,582 trading 2 contracts or $27,873 trading 3 contracts in ONE MONTH ! We know results like that are hard to believe so we had an independent accountant audit our results - click here for the audit letter. With results like these why are you not a student ?
One it is 2014 so they are probably gone. Second they immediately assume that they would have made the same amount if they would have just scaled up one or two contracts. Position sizing is more complex then that and I have seen systems crash by increasing their sizing by one contract.
