High/Low/Median

[Chris Coleman]

How can I plot a thick line across a chart of the high price for the last three days? I tried a formula I found on here but it did not work properly. Any help would be graciously appreciated.

Try the enclosed efs. This includes the current day as part of the three days. If instead you want the past three days the change to get those values is easy enough.

function preMain() {
    setPriceStudy(true);
    setStudyTitle("3dayhilo");
    setShowCursorLabel(false);
      
}
function main() {

var vSymbol = getSymbol();
    vSymbol += ",D";

var vHigh = getValue("High",0,-3,vSymbol);
var vLow  = getValue("Low",0,-3,vSymbol);

var vHH = Math.max(vHigh[0],vHigh[1],vHigh[2]);
addBand(vHH,PS_SOLID,3,Color.blue,"high");

var vLL = Math.min(vLow[0],vLow[1],vLow[2]);
addBand(vLL,PS_SOLID,3,Color.red,"low");

return;
