The average true range is an N-day smoothed moving average (SMMA) of the true range values.Wilder recommended a 14-period smoothing.he range of a day's trading is simply. The true range extends it to yesterday's closing price if it was outside of today's range. The true range is the largest of the: 1  Most recent period's high minus the most recent period's low. 2  Absolute value of the most recent period's high minus the previous close.
it yields mean = 4 and Standard deviation = 2.16025 . In the second version lets consider Y = {1,2,3,4,5,6,100} This range of values gives a mean = 17.28571 and a Standard deviation = 36.51353. Even the mean is not increasing that much the standard deviation is now much higher. That means that there are values (100) very for from the mean.
