Smoothed Moving Average, SMMA shows a smoothed average value of the instrument price for a specific time period. To calculate the Smoothed Moving Average, the instrument price is averaged mathematically for that period. While the price changes, its average either increases, or declines.

Smoothed moving average (SMMA)

The first value of this smoothed average is calculated as the simple moving average (SMA).

Sum1 = SUM (CLOSE (i), (N))


The second and next smoothed averages are calculated by the following formula:

SMMA (i) = (SUM1-SMMA (i-1) CLOSE (i))/N


SUM —  the sum;

Sum1 - the sum of closing of N periods counted from the previous bar; 

SMMA (i-1) — smoothed moving average of the previous bar;

SMMA (i) — smoothed moving average of the current bar (except the first one);

Close (i) — current price of closing;

N — period of smoothing.
