  • VIDYA Code fails realtime, please help...

    Reference to this link...



    View the VIDYA (black line in EBAY..., the incorrect one has the black one on the last bars close (first file ), where it should be at the lower level. (Second file).

    Maybe calc should stop on the previous bar, I mean the second to last bar on the right hand side of the chart...

    Please help

    CODE****************
    var AbsCMO = 0.0;
    var CurrentBar = 0;
    var VIDYA = 0.0;
    var VIDYA_1 = 0.0;
    var lastbar = 0;

    function preMain()
    {
    setPriceStudy(true);
    setStudyTitle("IansVIDYA");
    setCursorLabelName("VIDYA", 0);
    setDefaultBarFgColor(Color.black, 0);
    }

    function main(Length, Smooth)
    {
    if (Length == null) { Length = 20; }//5 min 12, 2 min 20
    if (Smooth == null) { Smooth = 10; }//5 min 5, 2 min 10

    if (lastbar != getValue("rawtime",0)) {
    CurrentBar += 1;
    VIDYA_1 = VIDYA;
    }

    var BarState = getBarState();
    var UP = 0.0;
    var DN = 0.0;
    var UpSum = 0.0;
    var DnSum = 0.0;
    // var Close = getValue("Close", 0, -(Length + 2));
    var i;
    for (i = 0; i > 0-(Length-1); i--) {
    if (close(i) > close(i-1)) { UP = (close(i) - close(i-1)); } else { UP = 0.0; }
    if (close(i) < close(i-1)) { DN = (Math.abs(close(i) - close(i-1))); } else { DN = 0.0; }
    UpSum += UP;
    DnSum += DN;
    // debugPrintln("Vidya : ["+i+"] "+UpSum+" : "+DnSum);
    }
    // debugPrintln("Vidya : "+UpSum+" : "+DnSum);
    if ((UpSum+DnSum) > 0) { AbsCMO = Math.abs((UpSum-DnSum)/(UpSum+DnSum)) ; }
    var SC= 2/(Smooth+1);
    if (CurrentBar <= Length) { VIDYA = close(); } else { VIDYA = (SC * AbsCMO * close()) + ((1 - (SC * AbsCMO)) * VIDYA_1); }

    if (BarState == BARSTATE_NEWBAR) { VIDYA_1 = VIDYA; }

    return VIDYA;
    }

    Correct view, this is view on when symbol first loaded, the one above is after realtime data enters chart...

      I would guess after looking at the code and looking at the results that you are seeing the "drift" issue associated with an incorrectly coded EFS.

      If you do a search on drift, you will find a description of the problem and ways to fix your code.

      If this doesn't help you, just let me know and I will fix the code for you...would do it now but I'm about to head out for a few hours.

        Hi,

        Thx for your thoughts, Doji3333 helped me with some code on the previous post, and the code is way beyond my skills, so if you would be so kind as to fix the drift issue. I have done searches, but I dont have the skills beyond the basics. I hope you get the chance to fix and also test it in realtime conditions.

        Thx in advance
