Cursor Window Values

[mbuta]

Hi,
Can anyone explain why the values in Cursor Window [sometimes] show zero [0] while the study is around +/-1?

Please use ar reference the following example:

var vCCI3 = cci(3, "close");

return vCCI3.getValue(0)/100;



Thank you

FWIW the syntax in the example you provided is incorrect for both the efs1 and the efs2 CCI functions.

Alex,
I saw that, but it is not the issue here.
Has anyone tried?
Does anyone has an explaination?
Thank you.

Please post an image [of the Cursor Window and Formula Output Window] showing the discrepancy or provide a specific example (symbol, interval , study settings, etc) in which it occurrs so that others can try to replicate the same conditions.

Ok,

Here it is:

var stCCI3=cci(3);
return stCCI3.getValue(0)/100;

Hello Mihai,

The zeros that are appearing in the cursor window appear to be a rounding bug. The number is actually 0.9999999999999964 on the chart, the cursor window is just not displaying it correctly. I will report this to our development team. Thank you for posting.

function preMain() {
    //setPriceStudy(true);
    setStudyTitle("test");
    //setShowCursorLabel(false);
    setCursorLabelName("data", 0);
    setCursorLabelName("string", 1);
    //setCursorLabelName("L", 1);
    //addBand(1.8500, PS_SOLID, 1, Color.blue, "tag");
}

var stCCI3 = null;

function main() {
    if (stCCI3 == null) stCCI3 = cci(3);
    var n = stCCI3.getValue(0);
    var ret = n / 100;
    
    return new Array(ret, ret+"");
}

Hello Mihai,

In the mean time, here is a work-around for the problem. Round the .getValue() result before dividing by 100. I think the source of the problem is related to floating point representation of numbers in javascript. The following code will fix the display in the cursor window.

function preMain() {
    //setPriceStudy(true);
    setStudyTitle("test");
    //setShowCursorLabel(false);
    setCursorLabelName("data", 0);
    setCursorLabelName("string", 1);
    //setCursorLabelName("L", 1);
    //addBand(1.8500, PS_SOLID, 1, Color.blue, "tag");
}

var stCCI3 = null;

function main() {
    if (stCCI3 == null) stCCI3 = cci(3);
    var n = stCCI3.getValue(0);
    if (n == null) return;
    
    var ret = (n.toFixed(6)*1) / 100;
    
    if (getCurrentBarIndex() == -35) {
        debugPrintln(n);
    }
    
    return new Array(ret, ret+"");
}

Hi Jason,

Thank you and sorry for the late reply.
I did something similar: I divided by 99.995.

Thank you again.
