Abbreviation: StndNormZScore
Category: Statistical

Input Parameters:

Name Range Default
Time Series Close
Periods Int >= 2 10

 
Calculation:

X – mean( X) 

StndDev(X, n) 

where
mean(X) = mean average of X over the last n periods

X = Time Series
n = Periods

StndDev represents Standard Deviation

 
Discussion:

Provides a measure of a time series value relative to its mean expressed relative to its standard deviations. A value of one indicates a value one standard deviation above the mean, while a value of two indicates a value two standard deviations above the mean. Likewise, a value of negative one indicates a value one standard deviation below the mean, while a value of negative two indicates a value two standard deviations below the mean.
