problem solved if you put the FillArrays in OnTick and remove timer

void OnTick()
 {
  FillArrays(InpHeikTimeframe,ArrayIndex,D_heike_array);
  FillArrays(_Period,ArrayIndex,cur_heike_array);
   double ma=EMA_H(cur_heike_array,1);
   double ma_d = EMA_H(D_heike_array,1);
   
   Print("MA=",ma);
   Print("ma=",ma_d);
 }

This is what I get when I close . All values are correctly printed, but when I close EA I get this error

 

Yes. It does not work. I don't know why I thought it is working.

This is even simpler but it does not work.

double cur_heike_array[];

int OnInit()
 {
   FillArrays(30,cur_heike_array);
   return(INIT_SUCCEEDED);
 }
void OnTick()
 {
   double ma=EMA_H(cur_heike_array,1);
   Print("MA=",ma);
 }

double EMA_H(double &array[],int shift) 
 { 
   return(iMAOnArray(array,WHOLE_ARRAY,21,0,MODE_EMA,shift)); 
 }

void FillArrays(int sArrayIndex,double &array[])
 {
  ArrayResize(array,sArrayIndex,0);
  for(int i=0; i<sArrayIndex; i++)
    array[i]= 1;
 }

Can you provide full code that compiles to reproduce this issue ?
Hello! Any thoughts? Thank you!

Hello! Any thoughts? Thank you! 
It's an MT4 bug.

It's an MT4 bug.
Thank you! 
 

This is only happening when array is passed by refrence:

int array [] = { 2,45,56}

  double EMA_DIR(int &arr[] , int buff){return (iMAOnArray(arr,WHOLE_ARRAY,InpMAPeriod,0,MODE_EMA,buff));}  

if array is accesed whithin the function

int array[] = {1,34,56};

  double EMA_DIR(int buff){return (iMAOnArray(array,WHOLE_ARRAY,InpMAPeriod,0,MODE_EMA,buff));}  

it will not give any error
