Develope An EFS that has a " Color" as condition

[fabrizio]

I wonder if I can use the color of a study as condition in a EFS.
In some of my TS (or signals) I always wished to , but unfortunately Nor CQG nor Trade S. allow it.

( I.e. if the colour of TJTI is above or below (n) and yellow do not do it if above or below (n) but is blue or red do it)

Thanks

The following code shows an example of how you can reference the colors of the JTI.
In this case I am painting the bars in the corresponding JTI colors only if the JTI is less than -30 and the color of JTI is blue or red.

//var study = new GetJTIStudy(LengthBand1, LengthBand2, FastMode, TrendLength)

var study = new GetJTIStudy(30, -30, false, GetJTIStudy.SHORT);

//FastMode can be true OR false
//TrendLength can be .SHORT .MEDIUM .NORMAL .LONG

var vLastAlert = -1;

function preMain() {

    setPriceStudy(true);//this study does not plot the indicator
    setStudyTitle("JTI paintbar");
    setColorPriceBars(true);
}

function main() {

var vJTI=study.getValue(GetJTIStudy.JTI);//this returns the values
var cJTI=study.getValue(GetJTIStudy.COLORS);//this returns the colors

//color values are the following 0=noise, 1=low, 2=medium, 3 strong
 
        if (vJTI<-30&&cJTI==2)//IF JTI < -30 AND color = blue (medium)
        onAction1()//THEN perform this action (see command below)
 
        else if (vJTI<-30&&cJTI==3)//IF JTI ,-30 AND color=red (strong)
        onAction2()//THEN perform this action
        
        else if(1==1)//IF any other condition is true
        onAction3();//THEN perform this action
    
    return null;
}

    function onAction1() {
        setPriceBarColor(Color.blue);//paint bars blue
        vLastAlert = 1;
    }
   
    function onAction2() {
        setPriceBarColor(Color.red);//paint bars red
        vLastAlert = 2;
    }
    
   function onAction3() {
        setPriceBarColor(Color.black);//paint bars black
        vLastAlert = 3;
    }

Thanks a lot!

I will post here the PHP of the development of the TS ( maybe with a little help....)

Thanks again

Hello fabrizo,

You have a large section of your formula repeated at the bottom starting at line 52. Remove the code from that line down and you're good to go.

//var study = new GetJTIStudy(LengthBand1, LengthBand2, FastMode, TrendLength)

var study = new GetJTIStudy(30, -30, false, GetJTIStudy.SHORT);

//FastMode can be true OR false
//TrendLength can be .SHORT .MEDIUM .NORMAL .LONG

var vLastAlert = -1;

function preMain() {

    setPriceStudy(true);//this study does not plot the indicator
    setStudyTitle("JTI paintbar");
    setColorPriceBars(true);
}

function main() {

var vJTI=study.getValue(GetJTIStudy.JTI);//this returns the values
var cJTI=study.getValue(GetJTIStudy.COLORS);//this returns the colors

//color values are the following 0=noise, 1=low, 2=medium, 3 strong
 
        if (vJTI<-30&&cJTI==2)//IF JTI < -30 AND color = blue (medium)
        onAction1()//THEN perform this action (see command below)
 
        else if (vJTI<-30&&cJTI==3)//IF JTI ,-30 AND color=red (strong)
        onAction2()//THEN perform this action
        
        else if(1==1)//IF any other condition is true
        onAction3();//THEN perform this action
    
    return null;
}

function onAction1() {
    setPriceBarColor(Color.blue);//paint bars blue
    vLastAlert = 1;
}
   
function onAction2() {
    setPriceBarColor(Color.red);//paint bars red
    vLastAlert = 2;
}
    
function onAction3() {
    setPriceBarColor(Color.black);//paint bars black
    vLastAlert = 3;
}

If I cancel from line 52 on , I cancel the whole conditions that should be set IF JTI is >30 and BLUE or RED so , in other words the LONG condition of the formula, being the first part the SHORT side.

Can expalin me -even just by structure- how should I replicate the ABOVE part of the formula but in the other "direction" ( JTI>30 and BLUE or RED but not YELLOW)?

[eSignal_JasonK]

Hello fabrizo,

In your original formula, some of your code in main() plus the 3 onAction() functions inadvertently was copied and then pasted below onAction3(). If you look at your original formula, you'll see that you have duplicates of the 3 onAction() functions plus a duplicate section of the code from main(). Your formula really only has about 50 lines. Line 52 that was generating your error was the beginning of the duplicate code that was in main() above. That block of code starting at line 52 ended up outside the main() function. "vJTI" was not initialized in the global scope (outside main()) so that why you got the “not defined” error.

Hi,

I saw this chart, has formula color bar in background. I know how to do this in ravenquote. Can I do in 7.4?

Can you post a php example? I would be particularly interested in this color bar. RSI(4 )< 50 , RSI(4 )> 50.

chart with color bar background

TIA,

~j

[eSignal_JasonK]

Yes J,

The EFS function that colors the background is setBarBgColor().

function main() {
    if (getCurrentBarIndex() > -20 && getCurrentBarIndex() < -10) {
        setBarBgColor(Color.green);
    }
}

I think Fabrizio was trying to add the uptrend JTI signals to my original formula that was only set up to highlight downtrend signals. That is why he added those extra lines of code.

Fabrizio
To do what you wanted it was sufficient to change Lines 24 and 27 respectively to the following

if (vJTI<-30&&cJTI==2||vJTI>30&&cJTI==2)

else if (vJTI<-30&&cJTI==3||vJTI>30&&cJTI==3)

Notice the || sign which means OR. So the condition in Line 27 for example would now read
"IF JTI (value) is less than -30 and JTI (color) is red OR JTI (value) is greater than 30 and JTI (color) is red THEN...

However this will paint both the uptrend and downtrend bars of similar strength in the same color which can be confusing if you are not plotting the indicator.
You may find it preferable to paint for example the uptrend bars in lime for MEDIUM and blue for STRONG and the downtrend bars in yellow for MEDIUM and red for STRONG.
The following code should do that.

//var study = new GetJTIStudy(LengthBand1, LengthBand2, FastMode, TrendLength)

var study = new GetJTIStudy(30, -30, false, GetJTIStudy.SHORT);

//FastMode can be true OR false
//TrendLength can be .SHORT .MEDIUM .NORMAL .LONG

var vLastAlert = -1;

function preMain() {

    setPriceStudy(true);//this study does not plot the indicator
    setStudyTitle("JTI paintbar");
    setColorPriceBars(true);
}

function main() {

var vJTI=study.getValue(GetJTIStudy.JTI);//this returns the values
var cJTI=study.getValue(GetJTIStudy.COLORS);//this returns the colors

//color values are the following 0=noise, 1=low, 2=medium, 3 strong
 
        if (vJTI<-30&&cJTI==2)//IF JTI < -30 AND color = blue (medium)
        onAction1()//THEN perform this action (see command below)
 
        else if (vJTI<-30&&cJTI==3)//IF JTI ,-30 AND color=red (strong)
        onAction2()//THEN perform this action
        
        else if (vJTI>30&&cJTI==2)
        onAction3()
        
        else if (vJTI>30&&cJTI==3)
        onAction4()
        
        else if(1==1)//IF any other condition is true
        onAction5();//THEN perform this action
    
    return null;
}

    function onAction1() {
        setPriceBarColor(Color.yellow);//paint bars yellow
        vLastAlert = 1;
    }
   
    function onAction2() {
        setPriceBarColor(Color.red);//paint bars red
        vLastAlert = 2;
    }
    
   function onAction3() {
        setPriceBarColor(Color.lime);//paint bars lime
        vLastAlert = 3;
    } 
    
    function onAction4() {
        setPriceBarColor(Color.blue);//paint bars blue
        vLastAlert = 4;
    } 
    
    function onAction5() {
        setPriceBarColor(Color.black);//paint bars black
        vLastAlert = 5;
    } 

The result is shown in the chart below.
Hope this helps

I followed your instructions so I realized first a ( || ) version of your original formula just to get acquainted with the operator.
Then I carefully red your PHP and realized the new one with the (if else) and the new colors.

I made a correction for a mistype at line 24.

All works fine.

Now the eventual aim is to use THIS formula as a further condition for an already realized and thorough fully BT and real world operated TS of mine.

Question: May I "call" this study as a whole condition inside an efs? I believe yes but how?

Thanks a lot Alexis
