Range of intraday session

[maninjapan]

hi, I have an indicator that I have coded that records the range for a specific time of day. The indicator itself works fine, however since I have started using this I have begun experiencing issues with my Esignal connection. When I open a page some charts get stuck on requesting data. The specific charts that get stuck change from time to time, so I don't believe it is product specific. I have spoken with Esignal support a number of times and their solution is do a complete reinstall and rebuild all my pages and charts from scratch. However with the amount of charts and pages I have setup this is something I am extremely loathe to do. I'm far from an Esignal code expert, so I was wondering if this problem was somehow related to the way I have coded this indicator? ( it is so inefficiently coded it uses huge amounts of resources, unneccesarily, to load up. This indicator runs on about 40 charts on one page with 3 session times on each chart.

I just want to try and rule out absolutely everything else before having to do a full reinstall. Any help or suggestions would be greatly appreciated!! Below is the code in its entirety.

var rng = null;
var CMEEUR = null;
var val = null;
var ddeCMEEUR = null;
var X=1;
function preMain() {
    setPriceStudy(false);
    setStudyTitle("CME Euro Range");
    setCursorLabelName("CME Euro Range");
    setDefaultBarStyle(PS_SOLID, 0);
    setDefaultBarFgColor(Color.blue, 0);
    setDefaultBarThickness(5, 0);
    setPlotType(PLOTTYPE_HISTOGRAM, 0);
}

function main()
{

if (getHour(0) >= 3 && getHour(0) < 7 && day(0) == day(-1))
{
if(getBarState()==BARSTATE_NEWBAR){
//volus+=volume(-1);
X += 1;
if(X>1){
rng = efsInternal("HHH");
val = highest(X, rng);
CMEEUR = val.getValue(0)

    if (ddeCMEEUR == null){
    var sName = "CMEEUR" + getSymbol() + getInterval();
         sName = sName.replace(/\$/g, ""); // remove $ from string
        sName = sName.replace(/\#/g, ""); // remove # from string
        sName = sName.replace(/\-/g, "");
        sName = sName.replace(/\(/g, "");
        sName = sName.replace(/\!/g, "");        
        sName = sName.replace(/\=/g, "");
        sName = sName.replace(/\:/g, "");
        sName = sName.replace(/\)/g, "");
        sName = sName.replace(/\ /g, "_") // replace space with underscore
        debugPrintln("DDE Link for Excel =eSignal|EFS!"+sName);
        ddeCMEEUR = new DDEOutput(sName);
        }
   }

}
ddeCMEEUR.set(CMEEUR);
}else{
if (getHour(0) >= 7 || getHour(0) <= 2 || day(0) != day(-1)){
X=1;
CMEEUR = 0;
}
}
return CMEEUR;
}
var Highest = null;
var W =1;
function HHH() { 
    //if(!isIntraday()) return; //otherwise "gt" won't equal the start and end times 
    if (getHour(0) >= 3 && getHour(0) < 7 && day(0) == day(-1))
    {
    if(getBarState()==BARSTATE_NEWBAR){
    W += 1;
    }
    if(W>1){
    var HIGH = highest(W-1, high());
    var LOW = lowest(W-1, low());
    //if (getHour(0)==11 && getMinute(0)==55)
    //{
    Highest = HIGH - LOW//Math.abs(highest(48, high(),-1) - lowest(48, low(),-1));
    //}
    }
   }else{Highest=0;W=1;}
    return Highest;
