3 formulas ... help pls

[erilein]

Hi there i have coded a formula which calls 3 formulas to check if the conditions are true....

function preMain() {
    setPriceStudy(true);
    setStudyTitle("Special - Ver. 2 Beta");
    setDefaultBarFgColor(Color.blue,0);
    setDefaultBarFgColor(Color.red,1);
}
var study = new MAStudy(35,0, "OHLC/4", MAStudy.WEIGHTED);
function main() {
//-AUSGABE-
var out = 0;
//-Ausgabe-
var a = -1;
var sBTMA = 3;
var sPREF = 3;
var v = study.getValue(MAStudy.MA);
var vRSI = -2;
var vStochRSI;
//PREF
var test = new Array(2);
test = call("/Eric/Pref.efs","main");
return new Array(test1,test2);

if (MAVtx<MAVt1x)
    if (sPREF != 2)new Number(out - 1);    
    sPREF = 2;
if (MAVtx>MAVt1x)
    if (sPREF != 1)new Number(out + 1);    
    sPREF = 1;    
//BTMA
if(close() >= v) {
    if (sBTMA != 1)new Number(out + 1);    
    sBTMA = 1;
    }
if(close() < v) {
    if (sBTMA != 2)new Number(out - 1);    
    sBTMA = 2;
    }
//RSI
vStochRSI = call("/Eric/RSI.efs","main");
if(vStochRSI >= 100){
        a = 1;
    }
    if(vStochRSI <= 0){
        a = 0;
    }

    if(a == 1 && vStochRSI > 0){ 
        //HOCH
        if (vRSI != 1)new Number(out + 1);
        var vRSI = 1;

    }
    if(a == 0 && vStochRSI < 100){ 
        setBarBgColor(Color.RGB(255,0,0));
        //RUNTER
        if (vRSI != 2)new Number(out - 1);
        var vRSI = 2;
     }
//HAUPT!
if ( out <= -2 ){
setBarBgColor(Color.RGB(255,0,255));
Alert.addToList(getSymbol(), "Runter!", Color.RGB(0,0,0), Color.RGB(195,0,0));
}
if ( out >= 2 ){
setBarBgColor(Color.RGB(0,128,128));
Alert.addToList(getSymbol(), "Hoch!", Color.RGB(0,0,0), Color.RGB(0,255,0));

}


return vStochRSI;
return v;
} 

i use the btma35, the stochrsi and the preffered stochastic...

i dont know if i can attach 3 files but i will test it

There seem to be some errors in your formula that combines the signals amongst which is using call() with the syntax of callFunction().
With regards to this subject you may want to check this thread to which I am about to add a second part dedicated to calling efs(s) that return arrays.

In the mean time attached is an example of your btma35 that uses pref.efs to confirm signals. In fact only when btma35 and pref.efs are both long or short is the corresponding signal generated (see enclosed chart with pref plotted for comparison).
This is only an example to illustrate the use of callFunction in light of what you are trying to achieve. Save it in the same directory in which you have pref.efs.

I still believe it would be easier to first compute the conditions and generate the signals in the individual efs(s) as suggested in this message then simply combine those signals into one "calling" efs.

yes i read the threads ... but i dont know where the bug is...

and i also dont know how to get the signals of 3 formulas to 1...
it would be great if there is a way to save vars to a textfile and read it with another...

i think at a script wich does the following ...

...e.g. we take the up trend:

-> Get var 1 from signal.txt
-> Write var 1(maybe + 1) in signal.txt

is this possible...

--EDIT--
Sorry i didnt see that thread where exactly this is written in...
so dont notice that

Click here to go to the thread where the read/write to file method is explained by Brad.
However while it is certainlu possible I think that is a much more complex way of doing it than setting up a call() or callFunction().

i read the thread now and it does only reply a large (ok 1 kb ) text file... where do i define that he only should get the first entry add 1 and then replace it...

i am looking @ the help central but couldnt find it this time...

...
if (MAVtx>MAVt1x){
setBarBgColor(Color.RGB(100,255,100));
f.open("rt+");
line = f.writeln( <<< OLD NUMBER -1 >>>);                      
f.close(); 
... 

how do i realize that the old number - 1 is the new value of the textfile ?!

Here is the problem when using callFunction() with pref.efs as it was posted.
When you use callFunction() in your combined formula you are going to get an error "ref[0] invalid parameter". The reasons for that error are explained in this thread.
Here is the pref.efs formula

    setStudyTitle("Preferred Stochastic TEST!!!");
    setCursorLabelName("percentK", 0);
    setCursorLabelName("percentD", 1);

var MAVt = null;
var MAVt1 = null;
var MAVt_1 = 0;
var MAVt1_1 = 0;
var BarCntr = 0; 

//----ATTENTION - CALLFUNCTION WORKS FROM HERE ONWARDS - IT DOES NOT SEE WHAT IS BEFORE THIS LINE-----
function main(nLength, nSmoothing, nSmoothings) {
    if(nLength == null)
        nLength = 14;

        return;


    for(j = 0; j < nLength; j++) {
        if(j == 0) {
            ll = vLow[j];

        } else {

        }
    }
    
        
    percentK = ((close() - ll) / (hh - ll)) * 100;
    if (isNaN(percentK) == false) MAVt = MAVt_1 + (percentK - MAVt_1) / nSmoothing;
    if (getBarState() == BARSTATE_NEWBAR) MAVt_1 = MAVt;
    if (isNaN(percentK) == false) MAVt1 = MAVt1_1 + (MAVt - MAVt1_1) / nSmoothings;
    if (getBarState() == BARSTATE_NEWBAR) MAVt1_1 = MAVt1;
    
    
    if(getBarState()==BARSTATE_NEWBAR){
     BarCntr += 1; 
    } 
    if (BarCntr > 8) {
    var vRef = ref(-1,-2); 
    var MAVtx = vRef[0][0];
    var MAVt1x = vRef[0][1];
    var MAVtxx = vRef[1][0];
    var MAVt1xx = vRef[1][1];
    }
    
    if (MAVtx<MAVt1x)
        setBarBgColor(Color.RGB(255,100,100));
    if (MAVtx>MAVt1x)
        setBarBgColor(Color.RGB(100,255,100));
    
        
    return new Array (MAVt,MAVt1);
} 

Notice that just before main() I added a line of text that says "ATTENTION - CALLFUNCTION WORKS FROM HERE ONWARDS - IT DOES NOT SEE WHAT IS BEFORE THIS LINE".
If you notice outside of main() is var BarCntr=0 which is needed by ref() to retrieve the prior values of MAVt and MAVt1.
The problem is callFunction() does not use that variable therefore it generates an error in the called efs.
So the first thing to do is move var BarCntr=0 into main().
Once you do that the error disappears as you will see in the next message

Having gone through the reasons why callFunction() could not work with pref.efs as it was written I would like to revisit my original suggestion which is that of generating the signals in the individual efs(s) and then calling and combining these signals from another efs.
Attached is a zip file with rsi(2).efs, pref(2).efs and Calling.efs. Save all three to the Eric folder (or any folder so long as they are all in the same folder).
Both rsi(2).efs and pref(2).efs have been modified to return only a 1 if Long or -1 if Short. If you were to load them on a chart you would only see a line that oscillates between these two values. Both efs have also been cleaned up where necessary.
Calling.efs instead uses callFunction to retrieve the signals from each efs and then if both are Long (ie 1) it will paint the bars in green and if both are Short (ie -1) it will paint the bars in red.
In the image below I have also added the individual plots of each called efs.
Hope this helps
Alex

well nice looks very good... now i am trying to get the ma in there... i tried to get the background color when u >= 2 or u <= -2
and i am trying to add +1 and -1 to u on trendchange on all the indicators ...
--- ok i got it ---
thanks for the great support... and sorry for my unusual posting times... i arrived from school just...
