Triangular Moving Average (TRIMA)
A double-smoothed simple moving average that gives more weight to the middle of the lookback period.
Usage
Use for extremely smooth trend identification. TRIMA is significantly smoother than a standard SMA but introduces more lag; it is ideal for identifying long-term cycles.
Background
The Triangular Moving Average is an SMA of an SMA. For a period N, it averages the values over N/2 periods twice. This results in a weight distribution that is triangular, peaking at the center of the window, making it very effective at filtering out high-frequency noise. — StockCharts ChartSchool
