Introduction
Triangular moving averages place the majority of the weight on the middle portion of the
price series. They are actually doublesmoothed simple moving averages. The periods used
in the simple moving averages varies depending on if you specify an odd or even number of
time periods.
The following steps explain how to calculate a 12period
triangular moving average.
 Add 1 to the number of periods in the moving average
(e.g., 12 plus 1 is 13).
 Divide the sum from Step #1 by 2 (e.g., 13 divided by 2 is
6.5).
 If the result of Step #2 contains a fractional portion,
round the result up to the nearest integer (e.g., round 6.5 up to 7).
 Using the value from Step #3 (i.e., 7), calculate a simple
moving average of the closing prices (i.e., a 7period simple moving average).
 Again using the value from Step #3 (i.e., 7) calculate a
simple moving average of the moving average calculated in Step #4 (i.e., a moving average
of a moving average).
