you are touching an interesting subject. Many traders look only at the commodity, the commodity they are riding, hoping for the Big One. It is very important to look at statistical trading performance.... what percentage of your trades profits... how big are your losers, how big are your winners? These ratios must be in a healthy relationship. to make the end-result good.. I have seen many traders win a few, lose a few, and then they ride one bad trade to oblivion.
