variable as a series

[sunman4008]

Hello,

How do you make a variable a series so you can access historical values with .getValue?

Hello Mike,
The following series example code is also included as a notepad attachment:

function preMain(){
setPriceStudy(true);
setStudyTitle("Forum Series Example")
}

var xCloseMinusUBB = null; // Global variable
var xCloseMinusLBB = null; // Global variable
var xHighestClose = null; // Global variable

function main(){
if(getBarState() == BARSTATE_ALLBARS){
var nCalcUBB = null;
var nCalcLBB = null;
var nHighestClose = null;
xCloseMinusUBB = efsInternal("CalcCloseMinusUBB") // No function parameters
xCloseMinusLBB = efsInternal("CalcCloseMinusLBB", close(), lowerBB(20, 2)); // Pass 2 function parameters
xHighestClose = highest(10, close()); // Use eSignal's series objects.
}
nCalcUBB = xCloseMinusUBB.getValue(0);
nCalcLBB = xCloseMinusLBB.getValue(-3);
nHighestClose = xHighestClose.getValue(-5);

if(getBarState() != BARSTATE_CURRENTBAR)
debugPrintln(getCurrentBarIndex() + "\t" + close(0) + "\t" + upperBB(20, 2, 0) + "\t" +
lowerBB(20, 2, 0) + "\t" + nCalcUBB + "\t" + nCalcLBB + "\t" + nHighestClose);
return;
}

function CalcCloseMinusUBB(){
return close(0) - upperBB(20, 2, 0)
}

function CalcCloseMinusLBB(nPrice, nLBB){
return nPrice.getValue(0) - nLBB.getValue(0);
}
