Moving Average Trend of Forecasting
A centered moving average (MA) is obtained by summing and averaging the values from a given number of periods repetitively, each time deleting the oldest value and adding a new value.
MA =    ∑x/ Number of Period
A weighted moving average (MAw) allows some values to be emphasized by varying the weights assigned to each component of the average. Weights can be either percentages or a real number.
MAwt   =      ∑ (Wt)/∑Wt
