Pivot Points

[buzybill]

I'm trying to make pivot point in my intraday chart. I have made this far, but something isn't working. can anyone direct my to right direction.

Thanks,

Billy


function preMain() {
setPriceStudy(true);
setStudyTitle("Pivot Range");
setCursorLabelName("Pivot Range");
setCursorLabelName("PR High",0);
setCursorLabelName("PR Low",1);
setDefaultBarStyle(PS_SOLID,0);
setDefaultBarFgColor(Color.black,0);
setDefaultBarThickness(2,0);
setPlotType(PLOTTYPE_FLATLINES,0);
setDefaultBarStyle(PS_SOLID,1);
setDefaultBarFgColor(Color.black,1);
setDefaultBarThickness(2,1);
setPlotType(PLOTTYPE_FLATLINES,1);
}

// initialization flag
var bInit = false;

// global variables for series objects
var xHigh = null;
var xLow = null;
var xClose = null;

function main() {

if (bInit == false) { // initialization routine occurs only once.
Symbol = getSymbol();
Interval = "D";
var vSymbol = Symbol+","+Interval;
xHigh = high(-1,sym(vSymbol));
xLow = low(-1,sym(vSymbol));
xClose = close(-1,sym(vSymbol));

bInit = true;
}

var pHigh = xHigh.getValue(0);
var pLow = xLow.getValue(0);
var pClose= xClose.getValue(0);

pivotRangeDiff = ((pHigh + pLow + pClose) / 3) - ((pHigh + pLow) / 2);
pivotRangeHigh = ((pHigh + pLow + pClose) / 3) + pivotRangeDiff;
pivotRangeLow = ((pHigh + pLow + pClose) / 3) - pivotRangeDiff;

return new Array(pivotRangeHigh,pivotRangeLow);
}

Hi
There are some examples in the Formuas\Pivots directory. In PivotPoints.efs see different use of high(), low() and close(), your "-1" needs dropping. and since you are using the same symbol, "inv()" is enough.

    if(bInit == false){
        xHigh  = high(inv("D"));
        xLow   = low(inv("D"));
        xClose = close(inv("D")); 
        bInit = true;
    }
    
    var vHigh  = xHigh.getValue(-1);
    var vLow   = xLow.getValue(-1);
    var vClose = xClose.getValue(-1); 
    if(vHigh == null || vLow == null || vClose == null)
    return; 

Good luck
Dave
