//  A Triangular moving average is similar to exponential and
//
//  weighted moving averages except a different weighting scheme
//
//  is used. Exponential and Weighted averages assign the majority
//
//  of the weight to the most recent data. Simple moving averages
//
//  assign the weight equally across all the data. With a Triangular
//
//  moving average, the majority of the weight is assigned to the middle
//
//  portion of the data.
