EFS vs. EFS2..

[Doji3333]

I just noticed something working on a clients code.. We were getting different results and I identified what I think might be an issue...

In this example, I've loaded the BASIC STUDIES MACD and the EFS 2 CUSTOM MACD on the same chart with the same settings (as best as I can tell)..

Now, look at the results on the selected bar..

BASIC STUDY:
MACD = -0.001
MACD SIG = -0.003
MACD HIS = 0.001

EFS2
MACD = -0.001
MACD SIG = -0.001
MACD HIS = -0.001

Now, what am I missing here?? What is the difference and are there other differences in other EFS2 indicators?? The EFS2 documentation does not include anything to show me I need to pass a unique value/parameter to the macd().

I'm confused????

Hello Brad,

The EFS2 built-in is based on exponential moving averages. The MACD study from the Basic menu has the option to do simple or exponential. It is set to simple by default.

For the Basic MACD, go into Edit Studies and uncheck the simple moving average option and it will match the EFS2 study.

cool

Jason,

Cool, thanks.. How do I get the EFS 2 to match the BASIC MACD?

Hello Brad,

At this time the EFS2 study does not have a simple moving average option. You could use the old EFS1 study. Or, if you need it in the form of a Series object then you could wrap it inside an efsInternal() call.

var xMACD = null;

function main() {
    if (xMACD == null) {  // initialize only once at start up
        xMACD = efsInternal("simpleMACD");
    }
    
    var nSig = xMACD.getValue(0);
    if (nSig == null) return;
    
    return nSig;
}


var myMACD = null;

function simpleMACD() {
    if (myMACD == null) myMACD = new MACDStudy(12, 26, 9, "Close", true, true);
    var Signal = myMACD.getValue(MACDStudy.SIGNAL, 0);
    if (Signal == null) return;
    
    return Signal;
}

Thanks buddy..

Thanks Jason,

I was kinda thinking I had to do it that way. Was hoping there was an easier fix... lol. You know, some "special parameter" or something..

Oh well, back to coding..
