I have configured my system the option of selecting 56 different methods of calculation of the forecast, but in some cases this provision does not fit reality. Articles especially true trend changing at any given time. Items that sold weekly 1 or 2 units go to sell 500 units, when I took several periods selling 500 units per week. The method that gets or is prone thereby anticipating the hit 1000 units per week because he believes it will continue to increase. Or does a very low forecast because it considers the previous periods. In this case, if only lame periods of change from the forecast will be correct, but that would force me to review items daily. It was a way to parameterize the system to have an accurate forecast of these items. Thank You
