Return close from specific time

[maninjapan]

I am using the current formula to return the close from the daily chart. However I would like to also return the price from a specific time of day (19:00). Is there a way to replace the close of Daily bar to return this price?
I only use this on an intraday chart

Thanks in Advance

var vLastAlert = -1;



function preMain() {
  
  
    setPriceStudy(false);
    setStudyTitle("Satosan Arb2");
    setCursorLabelName("?", 0);
    setDefaultBarStyle(PS_SOLID, 0);
    setDefaultBarFgColor(Color.red, 0);
    setDefaultBarThickness(2, 0);
    setPlotType(PLOTTYPE_LINE, 0);

}

function main() {
  

    return (close() - close(0,inv("D"))) / close(0,inv("D"));

}

function postMain() {
 
 
}

    function onAction1() {
        vLastAlert = 1;
    }

Hi, after a bit of snooping around on the
forum, I found the following that does what I need. However, this example is returning the value from the Previous day. How can I have it return today's 2:30 (not yesterdays)?

var nCloseDay1=null, nCloseDay0=null;
function main() {
if (getCurrentBarIndex() != 0) { // Are historical bars
if (getDay(0) != getDay(-1)) { // Is the first bar of a new day
nCloseDay1=nCloseDay0; 
}
if (getHour(0) == 14 && getMinute(0) == 30-getInterval(0)) { // Is your 2.30pm-inv bar
nCloseDay0=close(0);
}
debugPrintln("Inv: "+getInterval()+" H: "+getHour(0)+" M: "+getMinute(0)+" - Close 2.30 pm yesterday : "+nCloseDay1);
// nCloseDay1 is your value !!!
}
}

Actually I have been able to fix it by using the following

function main() {

nCloseDay1=nCloseDay0; 

if (getHour(0) == 15 && getMinute(0) == 30-getInterval(0)) { // Is your 3.30pm-inv bar
nCloseDay0=close(0);
}
 return (nCloseDay1)


}
