Hi GumRai, thank you so much for your help! :)

 

When I wrote it in here I've done that (stupid) declaration but I've declared the array in the EA like this:

(between external variables declaration and init function) 

double   DIF_MA[2];

double   WPR[]; 


I've got the EA working well with this while loop (calling the indicator with iCustom):

// Code to find crosses at bar number index

     index=0;
     ArrayIndex = 0;


     while(ArrayIndex <= 5)
     {       
         DIF_MA[0] = iCustom(NULL,0,"Signal - WPR (Smooth)",Periodo,Periodo_Smooth,2,index);
         DIF_MA[1] = iCustom(NULL,0,"Signal - WPR (Smooth)",Periodo,Periodo_Smooth,2,index+1);

         if( (DIF_MA[0]>0 && DIF_MA[1]<=0) || (DIF_MA[0]<0 && DIF_MA[1]>=0) )      // if cross found
         {
            CrossAt[ArrayIndex] = index;
            ArrayIndex++;
         }
         index++;
     }

 

And my intention was to "insert" the indicator in the EA.

Because the indicator is only to smooth the WPR indicator with a certain period.

My idea was to create an array called WPR[] with that for cycle and than use it with the iMAOnArray in the while cycle instead of calling the custom indicator.

 

// Code to find crosses at bar number index

index=0;
ArrayIndex = 0;

ArrayResize(WPR,Periodo+1);
ArraySetAsSeries(WPR,true);

     
for (int g=0; g<=Periodo; g++)
{
   WPR[g] = iWPR(NULL,0,Periodo,g);
}
     

while(ArrayIndex <= 5)
{       
   DIF_MA[0] = (iMAOnArray(WPR,Periodo,Periodo_Smooth,0,MODE_SMA,index) +50);
   DIF_MA[1] = (iMAOnArray(WPR,Periodo,Periodo_Smooth,0,MODE_SMA,index+1) +50);

  if( (DIF_MA[0]>0 && DIF_MA[1]<=0) || (DIF_MA[0]<0 && DIF_MA[1]>=0) )      // if cross found
   {
    CrossAt[ArrayIndex] = index;
    ArrayIndex++;
   }
   index++;
}

 

 

I really don't understand why does it give me an endless loop this way and it does not with iCustom ! :(

  1. WPR contains Periodo values
  2. When index is zero
    DIF_MA[1] = (iMAOnArray(WPR,Periodo,Periodo_Smooth,0,MODE_SMA,index+1) +50);
    iMA requires Periodo_Smooth values. [index+1 ... index+1+Periodo_Smooth-1]
  3. while(ArrayIndex <= 5)
    ArrayIndex is only increased if a cross is found
  4. Dif_MA[1] is always bogus, no cross is found, infinite loop.

Thank you for your answer WHRoeder!

I think that I've already understood the problem.

I will see if I can fix it. As I am a newbie now I need to hard think how to solve it.

I will be back! :)

Thank you all for your patience.

Finally I understood my problem!!! 

I was so focused on the while cycle that I has not looking to the for cycle.. ;)

Hours looking for the obviously... ... It's hard to be newbie... LOL..

 

I need to know WPR_Smooth value in past values and I was doing it as I was only working with the current time..

Now, with a bigger WPR Array and with iMAOnArray counting all that array (zero value) it is finally working.

No need to have a signal indicator anymore!  :)

.

     index=0;
     ArrayIndex = 0;

// Code to find crosses at bar number index


     ArrayResize(WPR,(Bars-Periodo));
     ArraySetAsSeries(WPR,true);
     
     for (int g=0; g<=(Bars-Periodo); g++)
     {
         WPR[g] = iWPR(NULL,0,Periodo,g);
     }
     


     while(ArrayIndex <= 5)
     {       
         DIF_MA[0] = (iMAOnArray(WPR,0,Periodo_Suav,0,MODE_SMA,index)+50);
         DIF_MA[1] = (iMAOnArray(WPR,0,Periodo_Suav,0,MODE_SMA,index+1)+50);

         if( (DIF_MA[0]>0 && DIF_MA[1]<=0) || (DIF_MA[0]<0 && DIF_MA[1]>=0) )      // if cross found
         {
            CrossAt[ArrayIndex] = index;
            ArrayIndex++;
         }
         index++;
     }


Once again.. Thank you so much for your patience to help me! :)
