If C2 wants to "rate" folks or give something to focus upon there are a few things that would be of interest to any one with smarts, Average trade P &L minus est costs, then the sharpe ratio and a few more things we might come up with. As for the developer has to state the draw down and we hold his feet to the fire…Ok that can be done, but if the guy uses the linear trading approach then this is less of a problem.
There are other factors that a trader needs to deal with in order to stay sane. I have a friend who was once the #2 guy for tony robbins and was sent out as the "coach" to some famous traders. He tells me the biggest problem traders have is loneliness. I will see if he is able to do a free webinar this fall, when I do mine.
