While  working on a different trading platform some years ago (BioProfit) I found out that  the best metrics to judge a system was to judge the slope of the equity curve. It should be as straiight as possible, not neccessary as steep as possible  I wrote a routine that calculated the straight line for the equity curve based on the "least square" method and then calculated the deviation the eguity curve made from this straight line. It gives a measure of the "consistency" of the method which is very important. I wonder  if it is possible to create such a method. There is a choice "custom" in the choice of metrics in the Strategy tester. Is there documentation somewhere how to develop such a routie?
