Hi, Could someone help me with this? I would like to plot the average body size, as a custom indicator, in Metatrader. Programing is not my strong point. The calculation would be the average of the absolute (getting rid of the sign) of the difference between the open and close ie abs(open-close)/n I have tried messing about with atr.mq4 to do this but have failed. I would really appreciate some help. Regards Morty
