Drawing a Horizontal Line between two User Defined intraday time points

[TURLIES]

Hi,
Is it possible to draw a Horizontal Line between two user chosen points in time (eg:10:00am to 3:00pm)?
Thanks,
Paul

Hi,

Here is one way:

//debugClear();

function preMain() {
    var aFPArray = new Array();
    setPriceStudy(true);
    //setStudyTitle("");
    
    var x = 0;
    aFPArray[x] = new FunctionParameter("StartTime", FunctionParameter.NUMBER);
    with(aFPArray[x++]) {
        setName("Start Time (930)");
        setLowerLimit(0);
        setUpperLimit(2400);
        addOption(300);                                        
        addOption(930);
        addOption(2000);                                    
       setDefault(930);
    }
    aFPArray[x] = new FunctionParameter("EndTime", FunctionParameter.NUMBER);
    with(aFPArray[x++]) {
        setName("End Time (1630)");
        setLowerLimit(0);
        setUpperLimit(2400);
        addOption(1130);                                    
        addOption(1615);
        addOption(300);                                    
        setDefault(1615);
    }
    aFPArray[x] = new FunctionParameter("nThickness", FunctionParameter.NUMBER);
    with(aFPArray[x++]) {
        setName("Line Thickness");
        setLowerLimit(1);
        setDefault(3);
    }
    aFPArray[x] = new FunctionParameter("cColorH", FunctionParameter.COLOR);
    with(aFPArray[x++]) {
        setName("High Color");
        setDefault(Color.blue);
    }
    aFPArray[x] = new FunctionParameter("DrawHowMany", FunctionParameter.STRING);
    with(aFPArray[x++]) {
        setName("Draw For:");
        addOption("Last Day");
        addOption("All Days");
        setDefault(3);
    }
}

var vStartBar = null;
var vEndBar = null;
var startStop=false;
function main(StartTime,EndTime, nThickness, cColorH, DrawHowMany) {
    drawLineAtTimes(StartTime,EndTime, nThickness, cColorH, DrawHowMany);
}
function drawLineAtTimes(StartTime,EndTime, nThickness, cColorH, DrawHowMany){
    var nDate = getYear()+""+(getMonth()+1)+getDay();
    var barTime=((hour(0) * 100) + minute(0));
    var numOfLines=1;
    
    if(DrawHowMany=="All Days") numOfLines=nDate;

    if(day(0)!=day(-1)){
        startStop=false;
    }
    if (barTime>=StartTime && EndTime>=barTime && !startStop){
        vStartBar=getCurrentBarCount();   
        startStop=true;
    }
    if (barTime>=StartTime && EndTime>=barTime) {//uncomment the drawLineRelative you want & comment out the drawLineRelative you don't want 
        vEndBar=getCurrentBarCount();
        //drawLineRelative( vStartBar-getCurrentBarCount(), close(vStartBar-getCurrentBarCount()), vEndBar-getCurrentBarCount(), close(vEndBar-getCurrentBarCount()), PS_SOLID, nThickness,cColorH, "xLine1"+numOfLines);//draws line from close of start bar to close of end bar
        drawLineRelative( vStartBar-getCurrentBarCount(), close(vStartBar-getCurrentBarCount()), vEndBar-getCurrentBarCount(), close(vStartBar-getCurrentBarCount()), PS_SOLID, nThickness,cColorH, "xLine2"+numOfLines);//draws line at close of start bar 
    }

    return;
}

Thanks a lot Wayne, that does exactly what I want.

I was trying out the study on Saturday, and as default it displayed the line for the previous day (Friday) at the times I desired. The "Draw For" Menu option of "All Days" also worked fine. The "Last Day" option drew the line on the Friday again, but with it being a weekend day, I presume this worked fine also. Changing the "Draw For" Menu number from "3" to any other number made no difference, as it still drew the line on Friday, so I am unsure what this number does or if it was working correctly for me (I guess it is to display a specific number of lines)?

I was going to test these "Draw For" Menu options again this morning, with real time data being used by the study. Unfortunately I was unable to do this, as my computer developed a major issue on Sunday, and I have had to sent it back to the Manufacturer to be repaired.

Hi Paul,

The "Draw For" default is a copy and paste error. It should default to either "Last Day" or "All Days", whichever you prefer.
