Highest range of day

[maninjapan]

I am using the following to keep track of the highest range of a specific period. I am currently using a fixed period of 70, but I would like to return the highest range of the trading day. To do this, I would like to change this from a fixed number to 'bars since first bar of day' is there an easy way to code this in esignal? ( I use this in other software but Im not familiar with coding in esignal)>

Thanks,

var ddeAHH=null; 
var AHH=null;
var veMA=null;
var avg=null



function preMain() { 

    setStudyTitle("Highest High Range"); 
    setCursorLabelName("Range", 0); 
    setCursorLabelName("Average", 1); 
    setPlotType(PLOTTYPE_HISTOGRAM, 0); 
    setDefaultBarFgColor(Color.blue, 0); 
    setDefaultBarFgColor(Color.red, 1); 
     
 

} 

function main() {

 AHH = efsInternal("HHH"); //this line calls the function "range" and creates a series 
     veMA = highest(70,AHH); //the series is used as an input to the builtin study 
   
     avg = veMA.getValue(0)

    if (ddeAHH == null) {
        var sName = "AHH" + 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, "_") // replace space with underscore
        debugPrintln("DDE Link for Excel =eSignal|EFS!"+sName);
        ddeAHH = new DDEOutput(sName);
    } 
        ddeAHH.set(avg);

        return avg;

} 


var DClose = null;
var Highest= null;

//this is the separate function that calculates the range 
function HHH() { 

        
            Highest = Math.abs(high(0) - low(0));
   
    
    return Highest;

Thanks for the reply Wayne, Ive put this up on a chart, but I'm not exactly sure what this is doing though. The lookback period for highest is still 70. I would like the period to be the bars since first bar of day so it tracks the highest range of the day since the open. The last bar of the day will reflect the highest range of the day and start again the following day from the first bar.
Thanks

Just define - in whatever way you want - your first bar of the day and store its range then from that bar onwards compare the stored and current range values and store the highest of the two. See the enclosed screenshot for a basic example of this
Search the forum and you will find other examples of how to do this using also loops etc as the topic has been covered before
