MA of Any EFS. It Works!

[aladin31]

Make sure you point to a default efs file, in lines 11 & 12. In this program I pointed to "MyMA.efs". You can replace it with any file of your choice.


function preMain() {

setPriceStudy(false);
setStudyTitle("My EFS MA");
setCursorLabelName("My EFS MA", 0);
setDefaultBarStyle(PS_SOLID, 0);
setDefaultBarFgColor(Color.red, 0);


// DEFINE WHICH DEFAULT EFS FILE YOU WANT TO USE
var fp0 = new FunctionParameter("MyEFS", FunctionParameter.STRING);
fp0.setDefault("MyMA.efs");


var fp1 = new FunctionParameter("Length", FunctionParameter.NUMBER);
fp1.setName("Length");
fp1.setLowerLimit(1);
fp1.setDefault(5);
}

var aValue = null;

function main(MyEFS, Length) {

//insert the code for the custom study here

addBand(0, PS_SOLID, 1, Color.blue, 90000);

var vPlot = call(MyEFS);//replace close(0) with the return of the custom study

if (aValue == null) {
aValue = new Array(Length);
}
if (getBarState() == BARSTATE_NEWBAR) {
aValue.pop();
aValue.unshift(vPlot);
} else {
aValue[0] = vPlot;
}

var i=0;
var nSum = 0;
for (i = 0; i < Length; ++i) {
nSum += aValue[i];
}
var vSMA = nSum/Length;


return vSMA;
}
