A triangular moving average (TMA) applies weights to each day in a triangular shape. For example on a 7-day average the weights are 1, 2, 3, 4, 3, 2, 1, or the following graph shows a 15-day average. The middle prices in the period have the greatest weight, and the oldest or newest only a small weight.
It’s interesting to note TMA is equivalent to a twice-smoothed simple moving average of half period (see Simple Moving Average).
TMA[N] = SMA[floor(N/2)+1] of SMA[ceil(N/2)]
In Chart TMA is under “Low Priority” in the indicator lists.
