high of a specific bar throughout the day

[davemabe]

Is there a way to use the high() function to retrieve the high of a specific bar no matter what the current time of day happens to be?

For example, the high of the most recent 9:30 15 minute bar.

TIA.

Hello davemabe,

Yes there is. The best way to accomplish this is to create a series for these specific bars using efsInternal() in combination with high(). To get the high from the specified time stamp the series will also need to check the bar's time stamps with a combination of hour(), minute() and/or second(). Try the following.

function preMain() {
    setPriceStudy(true);
    setStudyTitle("High - 09:30");
    setCursorLabelName("0930 High");
    setShowTitleParameters(false);
    setPlotType(PLOTTYPE_FLATLINES);
    setDefaultBarThickness(2);
    
    var fp1 = new FunctionParameter("nTime", FunctionParameter.NUMBER);
        fp1.setName("Bar Time");
        fp1.addOption(830);
        fp1.addOption(930);
        fp1.addOption(1030);
        fp1.setDefault(930);
}

var xHigh = null;

function main(nTime) {
    if (xHigh == null) xHigh = efsInternal("getHigh", nTime);
    
    var nHigh = xHigh.getValue(0);
    if (nHigh == null) return;
    
    return nHigh;
}


var h = null;

function getHigh(nT) {
    var barTime = hour(0)*100 + minute(0);
    if (barTime == nT) h = high(0);
    
    return h;
}

Is it really necessary to code and call a function?

Can't you just store the high if the bar's time is the specified time?
