Use to measure how unusual a value is versus its history ($0.01)
Use to measure how unusual a value is versus its history ($0.01): send value and reference values; get mean, standard deviation and z = (value - mean) / sd. Choose SAMPLE (default, n-1) or POPULATION (n) standard deviation. Deterministic, works for prices, volumes, spreads or any series.
