The Composite Index

[panjan]

Does anyone know or have created "The Composite Index" indicator by Constance Brown in the eSignal software? I have attached the Meta Stock format. I would like to use this indicator in eSignal. If you can help please let me know. Thank You.

The Composite Index In The Metastock Format



A=RSI(14)-Ref(RSI(14),-9)+Mov(RSI(3),3,S);

Plot1 = Mov(A,13,S);

Plot2 = Mov(A,33,S);

A;Plot1;Plot2;

Yes,
I would also like an EFS version.

I can supply the TradeStation Format if it would he helpful to convert into EFS.

Cheers, Al.

Hi Ashraf,

I tried to do it. Here is the code. Hope it will be helpful.

function preMain() {

    setPriceStudy(false);
    setStudyTitle("Composite Index");
    setCursorLabelName("A",0);
    setCursorLabelName("SMA(13)",1);
    setCursorLabelName("SMA(33)",2);
    setDefaultBarFgColor(Color.lime,0);
    setDefaultBarFgColor(Color.blue,1);
    setDefaultBarFgColor(Color.red,2);
    setPlotType(PLOTTYPE_LINE,0); 
    setPlotType(PLOTTYPE_LINE,1); 
    setPlotType(PLOTTYPE_LINE,2); 
    setDefaultBarThickness(1,0);
    askForInput();
 
   
}

function calc(){
      //RSI(14)-Ref(RSI(14),-9)+Mov(RSI(3),3,S); 
    return rsi(14,0)-rsi(14,-9)+sma(3,rsi(3));
}


function main() {

    var A=efsInternal("calc");

    //Plot1 = Mov(A,13,S);
    var Plot1 = sma(13,A);
    
    //Plot2 = Mov(A,33,S);
    var Plot2 = sma(33,A);
 
 
    return new Array (A,Plot1,Plot2);
     
}

Guys, the Composite Index EFS doesn't update in real time on tick charts. Anyone with any ideas?
Cheers, Al.

I believe the issue is that you need to use the getSeries() function to retrieve the study series for it to plot.

Try the following (I added a "bInit" routine for efficiency so the series are created only once instead of on every tick):

function preMain() { 

    setPriceStudy(false); 
    setStudyTitle("Composite Index"); 
    setCursorLabelName("A",0); 
    setCursorLabelName("SMA(13)",1); 
    setCursorLabelName("SMA(33)",2); 
    setDefaultBarFgColor(Color.lime,0); 
    setDefaultBarFgColor(Color.blue,1); 
    setDefaultBarFgColor(Color.red,2); 
    setPlotType(PLOTTYPE_LINE,0);  
    setPlotType(PLOTTYPE_LINE,1);  
    setPlotType(PLOTTYPE_LINE,2);  
    setDefaultBarThickness(1,0); 
    //askForInput();  //function main() has no parameters to input
  
    
} 

function calc(){ 
      //RSI(14)-Ref(RSI(14),-9)+Mov(RSI(3),3,S);  
    return rsi(14,0)-rsi(14,-9)+sma(3,rsi(3)); 
} 
var bInit=false;
var A,Plot1,Plot2;
function main() { 
    if(!bInit){
        A=getSeries(efsInternal("calc")); 
        //Plot1 = Mov(A,13,S); 
        Plot1 = getSeries(sma(13,A)); 
        //Plot2 = Mov(A,33,S); 
        Plot2 = getSeries(sma(33,A)); 
        bInit=true;
    }
  
    return new Array (A,Plot1,Plot2); 
      
}

Waynecd, fantastic. Can't thank you enough. I'll put it to the test next week and let you know how it goes.
Cheers, Al.

Hope it works as you expect.

FWIW the original formula posted by emet works just fine and contrary to what waynecd states it does not require the getSeries() function to retrieve the series
