Writing in a file and the bar-index process

[Mermoz_2et]

Hi,
there is a problem I can't solve. I wrote a formula with many variables calculated not to display them but to write them into a file.
I have a difficulty to place code line (writing this file) within the code of the main function.
some explanations :
The variables I want to calculate must be evaluated at some very precise moment (very precise bar-index) which depends on some logical conditions. And I don't know in advance the indexes for each variable. Furthermore all the variables don't have the same indexes.
Do I have to write each variable separately or at the same time ?
I tried at the same time and it didn't work. Precisely, I tried to write at the end of the loop (after the last bar). But how can I know I am at the end of the loop ?

Thanks in advance for any help.

see below summary of my code :

function preMain(){
    setPriceStudy(true);
    setStudyTitle("writing of level");
    setShowTitleParameters(false);
}
var R3_D = null;
var R2_D = null;
var R1_D = null;
var PP_D = null;
var S1_D = null;
var S2_D = null;
var S3_D = null;

var R3_W = null;
var R2_W = null;
var R1_W = null;
var PP_W = null;
var S1_W = null;

var S3_W = null;

var R3_M = null;
var R2_M = null;

var S3_M = null;

var IdxD = 0;
var IdxW = 0;
var IdxM = 0;
var bRealTime= false;

var Valeur = null;
var precis = 5;

function main(){
   var nBarIndex = getCurrentBarIndex();
   var nBarState = getBarState();

    if(getBarStateInterval("d") == BARSTATE_NEWBAR){
        IdxD = nBarIndex;
        H_D = high(-1,inv("d"));
        L_D = low(-1,inv("d"));
        C_D = close(-1);
    }

    if(getBarStateInterval("w") == BARSTATE_NEWBAR){
        IdxW = nBarIndex;
        H_W = high(-1,inv("w"));
        L_W = low(-1,inv("w"));
        C_W = close(-1);
    }

    if(getBarStateInterval("m") == BARSTATE_NEWBAR){
       IdxM = nBarIndex;
        H_M = high(-1,inv("m"));
        L_M = low(-1,inv("m"));
        C_M = close(-1);
    }

    if(C_D == null || C_W == null || C_M == null) { return; }
    if(nBarIndex == 0 && nBarState == BARSTATE_CURRENTBAR){ bRealTime= true; }
    if(bRealTime && nBarState == BARSTATE_NEWBAR){
        IdxD--;
        IdxW--;
        IdxM--;
    }

// calculus
    // daily
    PP_D = (H_D + L_D + C_D) / 3;
    R1_D = 2*PP_D - L_D;
    S1_D = 2*PP_D - H_D;
    R2_D = PP_D + (H_D - L_D);
    S2_D = PP_D - (H_D - L_D);
    R3_D = 2*(PP_D - L_D) + H_D;
    S3_D = 2*(PP_D - H_D) + L_D;

    // weekly
    PP_W = (H_W + L_W + C_W) / 3;
    R1_W = 2*PP_W - L_W;
    S1_W = 2*PP_W - H_W;
    R2_W = PP_W + (H_W - L_W);
    S2_W = PP_W - (H_W - L_W);
    R3_W = 2*(PP_W - L_W) + H_W;
    S3_W = 2*(PP_W - H_W) + L_W;

    //Monthly
    PP_M = (H_M + L_M + C_M) / 3;
    R1_M = 2*PP_M - L_M;
    S1_M = 2*PP_M - H_M;
    R2_M = PP_M + (H_M - L_M);
    S2_M = PP_M - (H_M - L_M);
    R3_M = 2*(PP_M - L_M) + H_M;
    S3_M = 2*(PP_M - H_M) + L_M;

    // file open ...
        var Monfichier = new File("LeFichier.txt");
        Monfichier.open( "at" );

    //writing of the first variable
        Valeur = PP_M1.tofixed(precis);
        Monfichier.writeln("PP_M1 =" + Valeur);
     
    //writing of the second variable
        Valeur = R1_M1.tofixed(precis);
        Monfichier.writeln("R1_M1 =" + Valeur);
etc...
    Monfichier.close()
}

You can write the text any way you want. The way you're doing it from your example, you'll end up with a text file like..

PP_M1 = 102.34456
R1_M1 = 101.12335

If this is your objective, then you seem to have accomplished your goal.

To accomplish the "condition" of when to write the data file (text file), then you need to create some method of enclosing your FILE WRITE function into your condition... like...

if (getBarState() == BARSTATE_NEWBAR) {
  //  New bar - time to write data to a file

   ..  Add your file write function/actions here.
} 

Without knowing exactly how and when you want to write the data to the file, it's difficult for me to directly assist you.

What I can tell you is the way you have shown your code, you are writing the file every bar (in historical mode) and every TICK (in realtime mode). This is probably not what you wanted to accomplish.
