Storing series results in an array

[AssetHound]

I'd like to calculate several series and store them in an array. See below. I don't get an error message with this but the debugPrintln command for xAverage doesn't work. It only returns "[object series]." So, I don't know how to reference individual values within this array. Any help will be appreciated. Thanks.

var bInit = false;
var xSymbol = new Array();
var xAverage = new Array();
var xList = new Array ("XOM","INTC","ORCL","IBM","MMM");

function main() {
if (getBarState() == BARSTATE_NEWBAR) {
for (var i=0;i<5;i++) {
xSymbol[i] = xList[i]+","+getInterval();
xAverage[i] = ema(5,close(sym(xSymbol)));
}
}

// Calculate some index with all these series
debugPrintln(xSymbol[1]);
debugPrintln(xAverage[1]);
return; //calculated index (one number)
}

There are a couple of errors in the following line of your code
[i]xAverage = ema(5,close(sym(xSymbol)));
1. You are always only passing the first symbol of the xSymbol array. You need to modify xSymbol to [i]xSymbol
2. You are not assigning to [i]xAverage the value of the series but the series itself hence the [object series] returned to the Formula Output window by the efs engine. To accomplish what you want you need to also pass the bar index parameter to retrieve the value at the specific bar ie ema(5, close(sym(...)),0)
See this thread for a complete set of examples on retrieving values directly (ie without using the getValue() method)
