EFS error

Hello,

I have the following code. It gives me a invalid array. What am I doing wrong? When i do Array(1), it works well but I don't give any values.

-Mike


function main() {
var nNumberBars;
var nIndex = getCurrentBarIndex();

nNumberBars = getNumBars();

// if (bInit == false) {
KS = middleDonchian(27);
buffer = atr(5);
//drawShapeRelative(0,high(0)+buffer, Shape.SQUARE,null,Color.blue,Shape.TOP);
if (close(0) > KS.getValue(0) )
{
dotvalue = KS - buffer;
drawShapeRelative(0,dotvalue, Shape.CIRCLE,null,Color.green,Shape.TOP)
} else {

dotvalue = KS + buffer;
drawShapeRelative(0,dotvalue, Shape.CIRCLE,null,Color.green,Shape.TOP)
}


return new Array(dotvalue);

}

Hi Mike,

var bInit=false;
var KS,buffer;//make these global so they are available each iteration of main
function main() {
    var nNumberBars;
    var nIndex = getCurrentBarIndex();

    nNumberBars = getNumBars();

    if (bInit == false) {//use "bInit" routine to create the series only once
        KS = middleDonchian(27);
        buffer = atr(5); 
    }
    //drawShapeRelative(0,high(0)+buffer, Shape.SQUARE,null,Color.blue,Shape.TOP);
    if (close(0) > KS.getValue(0) )
    {
        dotvalue = KS.getValue(0) - buffer.getValue(0);//last value is needed not the full series
        drawShapeRelative(0,dotvalue, Shape.CIRCLE,null,Color.green,Shape.TOP)
    } else {
        dotvalue = KS.getValue(0) + buffer.getValue(0);//last value is needed not the full series
        drawShapeRelative(0,dotvalue, Shape.CIRCLE,null,Color.green,Shape.TOP)
    }


    return dotvalue;//don't use "new Array(...)" when returning only one value

}

Little tidbit. When you have multiple values to return, this:

return new Array(val1, val2, ...);

is the same as this:

return [val1, val2, ...];
