The enclosed efs uses callFunction() to call the values from PivotPointAll.efs.
Alex

PHP Code:


function preMain() {

    setPriceStudy(true);

    setStudyTitle("Call Pivots");

}



function main() {



    var aPivots = null;



    aPivots = callFunction("/Pivots/PivotPointAll.efs","main");

 

    if(aPivots == null) return;



    var r2 = aPivots[0]; 

    var r1 = aPivots[1];

    var pp = aPivots[2];

    var s1 = aPivots[3];

    var s2 = aPivots[4];



    return new Array (r2,r1,pp,s1,s2);

}

still having problems

thanks, the call function works great, but i can't seem to get it to work in conjunction with my program.

could the problem be the combination of using the call function inside the main function with the newbar_state?

In transferring my script into yours you also copied return new Array (vR2,vR1,vPP,vS1,vS2); which should not be there.
Also if you are only using vPP in your efs then you can comment out (or delete) the other variables (ie vR1, vS1, etc).
Anyhow to verify if you are retrieving vPP insert a debugPrintln(vPP); where appropriate and check the Formula Output Window.

Dear Alex,

Can you take a look at the attached efs script and see what is wrong? It is a simple Turn bar script that paints the bar when 3 conditions are met:

1. Low is lower than previous low
2. Close is above open
3. Close is above midpoint.

It seems to be having trouble with the 3rd parameter...

Thanks so much

Veda

Midpoint is (high+low)/2 not (high-low)/2 as is instead written in the efs.
Also an && is missing in the second conditional statement.
Alex

**vedaball** · 08-03-2004, 11:23 AM

Hi Alex,

I have made the correction you suggest but the script gets an error message on syntax. Could you get it to work?

Thanks

Veda

**vedaball** · 08-03-2004, 11:25 AM

Alex,

Ignore last pots - didn't see your comment about && missing. Works fine now

Thanks so much

Veda
