Function to return indicator's value...

New comment
 
I'm new, and would like to find a sample code to create a function that would return the numeric value of an indicator.

For example for the bear or bulls indicator.s

Could you give me a link or sample code ?

 
Just get the value(s) of the indicator(s) into the EA (using iCustom) and do what you want with it.
You should encapsulate your iCustom calls to make your code self-documenting.

Thank you.

I looked at iCustom and handle them.

Finally, I used the handle of the functions that interested me directly.

I do not know if it is correct but it seems to work as I wanted.

void OnTick()

   double BullsBuffer[]; 
   double BearsBuffer[];   
   int bullsPwr = iBullsPower(Symbol(), 0, 13);  
   int bearsPwr = iBearsPower(Symbol(), 0, 13);
  
    if(CopyBuffer(bullsPwr,0,0,1,BullsBuffer)<0)
     {
      Alert("Error copying indicator iBullsPower - error:",GetLastError(),"!!");
      return;
     }
    
    if(CopyBuffer(bearsPwr,0,0,1,BearsBuffer)<0)
     {
      Alert("Error copying indicator iBearsPower - error:",GetLastError(),"!!");
      return;
     }
     BullsBuffer[0]=NormalizeDouble(BullsBuffer[0],3);
     BearsBuffer[0]=NormalizeDouble(BearsBuffer[0],3);
     Comment("Bulls : ", BullsBuffer[0], "  Bears : ",BearsBuffer[0]);
