Sum

Contents

Finds the sum of the series. This function will not sum or total a sequence of comma limited values or expressions. For a non-array values totaling function see SumValues.

This example shows the use of the common auto indexed series. For information on using functions with non auto indexed series review Series Functions.

Syntax:
Sum( 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:
' -------------------------------------- ' Auto-Indexed Series Example ' Example Shows Sum of Bars 11 to 20 ' -------------------------------------- ' Find the sum of the 10 closes starting 20 bars ago sumCloses = Sum( instrument.close, 10, 20 ) ' -------------------------------------- ' Manually Index Series Example ' Example Shows Sum Values in Series ' for values shown. ' -------------------------------------- ' Set Series Size iSize = 10 ' OffSet Determines Range iOffSet = 10 ' Size Manual Index Series SetSeriesSize(X, iSize ) ' -------------------------------------- ' Loop Through Series For i = 1 TO iSize STEP 1 ' Assign Index value X[i] = i Next ' i ' -------------------------------------- ' Sum Value of X[] Series SumOfX = Sum(X, iSize, iOffSet ) ' -------------------------------------- PRINT "Total Value of Series = ", SumOfX ' -------------------------------------- ' Sum Value of X[] Series SumOfX = Sum(X, iSize-8, iOffSet ) ' -------------------------------------- PRINT "Total Value of Series = ", SumOfX ' --------------------------------------

Example:

' --------------------------------------
' Auto-Indexed Series Example
' Example Shows Sum of Bars 11 to 20
' --------------------------------------

' Find the sum of the 10 closes starting 20 bars ago
sumCloses = Sum( instrument.close, 10, 20 )

' --------------------------------------
' Manually Index Series Example
' Example Shows Sum Values in Series

' for values shown.
' --------------------------------------
' Set Series Size
iSize = 10
' OffSet Determines Range
iOffSet = 10
' Size Manual Index Series
SetSeriesSize(X, iSize )
' --------------------------------------
' Loop Through Series
For i = 1 TO iSize STEP 1
' Assign Index value
X[i] = i
Next ' i
' --------------------------------------
' Sum Value of X[] Series
SumOfX = Sum(X, iSize, iOffSet )
' --------------------------------------
PRINT "Total Value of Series = ", SumOfX
' --------------------------------------
' Sum Value of X[] Series
SumOfX = Sum(X, iSize-8, iOffSet )
' --------------------------------------
PRINT "Total Value of Series = ", SumOfX
' --------------------------------------

Returns:
Function returns the Sum or Total of the series elements specified. 1 = 1.000000000 SumX = 1 2 = 2.000000000 SumX = 3 3 = 3.000000000 SumX = 6 4 = 4.000000000 SumX = 10 5 = 5.000000000 SumX = 15 6 = 6.000000000 SumX = 21 7 = 7.000000000 SumX = 28 8 = 8.000000000 SumX = 36 9 = 9.000000000 SumX = 45 10 = 10.000000000 SumX = 55 Total Value of Series = 55 Total Value of Series = 19
