StandardDeviation

Contents

Function returns the Standard Deviation value of the series using the parameter adjustment values using the Population method.

This For information on using functions with non auto indexed series review Series Functions.

Syntax:

x = StandardDeviation( series, bars, [offset] )

Parameter:	Description:
series	Name of the series
bars	Number of bars over which to find the value
[offset]	Number of bars to offset before finding the value

Example:

' Example shows the use of the common auto indexed series.
VARIABLES: highestClose, highestHigh, lowestLow, averageClose, standDev TYPE: Price

' Find the highest close of the last 50 bars
highestClose = Highest( instrument.close, 50 )

' Find the lowest low of the last 100 bars
lowestLow = Lowest( instrument.low, 100 )

' Find the highest high since the entry of the first unit of the current position
IF instrument.position <> OUT THEN
highestHigh = Highest( instrument.high, instrument.unitBarsSinceEntry )
ENDIF

' Find the 10 day average of the close starting 20 days ago
averageClose = Average( instrument.close, 10, 20 )

' Find the standard deviation of the close over the last 100 days
standDev = StandardDeviation( instrument.close, 100 )

Results:

Standard Deviation value for each location in a series.
