Multiple Time Frames on 1 Chart

[alexmihh]

if you have a 1-min chart, and you have an efs that draws stochastics on it, can you code efs to draw the value of stochastics that at the current bar you would see if you had a 10-min chart opened, that is on the **same** 1 min chart?

[buzzhorton]

Yes, you can.

Does anyone have some sample code of how to do this?

You question prompted me to try something...

AND IT WORKED!

In the iStudy input of my TRO_SAK2 indicator, you can add ,inv(10)
to the study!

This ability makes the TRO STUDIES that much more flexible!!

Notice on the 1 minute chart how the 10 minute stochastic.. plots a flat line until the next 10 minute bar opens.

THIS IS REALLY COOL!

I made a 2 row version considering stochastics is usually a 2 line plot.

Can you save me some time and show me the part of efs code you used to do this? -- that is to draw a non 1 min Stohastic value on a 1 min chart (for example)

In its most basic form a Stochastic study based on 10 minute data is written as follows

function main(){
    return new Array ( stochK(14,1,3,inv(10)), stochD(14,1,3,inv(10)) );
} 

The interval on which the study is based is defined by the inv() function (see link for syntax and examples)
In your computer you can find an example of each builtin study in the EFS2 Custom folder of Formulas.
All those scripts include user adjustable parameters and are enabled for use with multiple intervals and/or external symbols

Alexis,

What would be the syntax for changing that statement to access and external symbol? Thanks very much.

To do that you would use the sym() function (see link for syntax and examples)
Alex

function main(){
    return new Array ( stochK(14,1,3,sym("IBM")), stochD(14,1,3,sym("IBM")) );
}

This may help.

I wrote a test study to see if you can use both the sym() and inv() in the same study... AND YOU CAN!

That will solve one of the problems I was having when building internal/external calls.

But back to main subject.

Notice, IWM is being charted but the stochastics for AAPL on a 10 minute interval are being displayed:

function preMain() {

    setPriceStudy(false);
    setStudyTitle("TRO_TEST"); 

    setDefaultBarFgColor(Color.red,0);
    setDefaultBarFgColor(Color.blue,1);

    setDefaultBarThickness(2,0); 
    setDefaultBarThickness(2,1);    
}

    var iSymbol = new FunctionParameter("iSymbol", FunctionParameter.STRING);
    iSymbol.setDefault( "AAPL" ); 


    var iInterval = new FunctionParameter("iInterval", FunctionParameter.NUMBER);
    iInterval.setDefault( 10 ); 

 askForInput();

function main(iSymbol, iInterval ){

return new Array ( stochK(14,1,3,sym(iSymbol), inv(iInterval)), stochD(14,1,3,sym(iSymbol), inv(iInterval)) );

}

Actually the script you posted will not work correctly and in fact the plot shown on your chart is not that of a 10 minute Stochastic of AAPL
The correct code is enclosed below together with an image showing the Stochastic based on the 10 minute data of AAPL
Anyhow as I indicated in my prior reply the customStoch.efs and other studies contained in the EFS2 Custom folder are already enabled to compute the studies based on external symbols and/or intervals and have all the significant parameters set to be user adjustable
Alex

function preMain() {

    setPriceStudy(false);
    setStudyTitle("TRO_TEST"); 

    setDefaultBarFgColor(Color.red,0);
    setDefaultBarFgColor(Color.blue,1);

    setDefaultBarThickness(2,0); 
    setDefaultBarThickness(2,1);    
    
    var iSymbol = new FunctionParameter("iSymbol", FunctionParameter.STRING);
    iSymbol.setDefault( "AAPL" ); 


    var iInterval = new FunctionParameter("iInterval", FunctionParameter.NUMBER);
    iInterval.setDefault( 10 ); 

    askForInput();
}
  

function main(iSymbol, iInterval ){

    return new Array ( stochK(14,1,3,sym(iSymbol+","+iInterval)), stochD(14,1,3,sym(iSymbol+","+iInterval)) );

}

Moving Study to Price via EFS

Uh, sort of a different question, but can these Stohastics value, which do not have price values, be drawn on the price chart?

That is, can we do with EFS what we do manually with our charts when we drag a study into the price chart with holding down the Shirt key, superimposing the study over the price bars?

If you are asking whether there is an efs function that will alow to overlay a study (just as you would do manually) then the answer is no there is no such function available at this time

Yeah, that was my question, and I sort of figured on your answer
