Todays open plus a certain number

[jjc]

hello

i would like to create an efs that takes the Today's Open and be able to add and subtract a certain number of my choosing to that today's open and have those 2 numbers displayed on the chart as lines

can you help me with that?

thx,
j

j, this is quite simple, I've just slightly modified the preinstalled Today's Open study:

//Developed by EMET
//Today's open and number of my choosing to that today's open

var fpArray = new Array();

function preMain() {
    setPriceStudy(true);
    setStudyTitle("Today's Open (TO)");
    setCursorLabelName("TO");

    setDefaultBarStyle(PS_DASH);
    setDefaultBarFgColor(Color.blue, 0);
    setDefaultBarFgColor(Color.red, 1);    
    setDefaultBarFgColor(Color.red, 2);        
    setDefaultBarThickness(2, 0);
    setDefaultBarThickness(2, 1);
    setDefaultBarThickness(2, 2);
    
    setPlotType(PLOTTYPE_FLATLINES, 0);
    setPlotType(PLOTTYPE_FLATLINES, 1);
    setPlotType(PLOTTYPE_FLATLINES, 2);    
    
//Other param
    askForInput();

    var x=0;
    fpArray[x] = new FunctionParameter("Displace", FunctionParameter.NUMBER);
    with(fpArray[x++]){
        setLowerLimit(0);        
        setDefault(0.5);
    }
    
}

var bInit = false;
var xOpen  = null;

function main(Displace) {
    
    if(isMonthly() || isWeekly() || isDaily())
    return;
    
    if(bInit == false){
        xOpen  = open(inv("D"));
        bInit = true;
    }
    
    var vOpen  = getSeries(xOpen);
    var vOpenInc  = vOpen + Displace;
    var vOpenDec  = vOpen - Displace;
    
    return new Array (vOpen, vOpenInc, vOpenDec);
}
