ON an EA (not for trading but only for reading buffers) which has a function SearchZigZagExtremums

I want this function to be converted into multi symbols  multi period

below is my attempt to modify the free program which is available in mql codebase

   if( ArrayResize(symbolsList, symbolCount) < symbolCount ) return (INIT_FAILED);

   for(int i=0; i<symbolCount; i++) {
      symbolsList[i] = SymbolName(i,true);
      handle_iCustom=iCustom(symbolsList[i],Period(),"Examples\\ZigZag");
//--- if the handle is not created
      if(handle_iCustom==INVALID_HANDLE) {
         //--- tell about the failure and output the error code
         PrintFormat("Failed to create handle of the iCustom indicator for the symbol %s/%s, error code %d",
                     symbolsList[i],
                     EnumToString(Period()),
                     GetLastError());

         //--- the indicator is stopped early
         return(INIT_FAILED);
      }
   }

   double array_results[];
 
      if(!SearchZigZagExtremums(4,array_results))
         return;
         
      double high=0.0,low=0.0;
      double room_0 = array_results[0]; // index 0
      double room_1 = array_results[1]; // index 1
      double room_2 = array_results[2]; // index 2
      double room_3 = array_results[3]; // index 3

//--- находим верх и низ
      if(room_1>room_2) {
         high=room_1;
         low=room_2;
      } else {
         high=room_2;
         low=room_1;
      }
     
      Print(symbolsList[j], array_results[0]);

   bool SearchZigZagExtremums(const int count,double &array_results[]) {
      if(!ArrayIsDynamic(array_results)) {
         Print("This a no dynamic array!");
         return(false);
      }
      ArrayFree(array_results);
      ArrayResize(array_results,count);
      ArraySetAsSeries(array_results,true);
      int      buffer_num=0;           // indicator buffer number
      double   arr_buffer[];
      ArraySetAsSeries(arr_buffer,true);
//--- reset error code
      ResetLastError();
//--- fill a part of the iCustom array with values from the indicator buffer
      int copied=CopyBuffer(handle_iCustom,buffer_num,0,100,arr_buffer);
      if(copied<0) {
         //--- if the copying fails, tell the error code
         PrintFormat("Failed to copy data from the iCustom indicator, error code %d",GetLastError());
         //--- quit with zero result - it means that the indicator is considered as not calculated
         return(false);
      }
      int elements=0;
      for(int i=0; i<copied; i++) {
         if(arr_buffer[i]!=0) {
            array_results[elements]=arr_buffer[i];
            elements++;
            if(elements==count)
               break;
         }
      }
      if(elements==count)
         return(true);
//---
      return(false);
   }


Goal : I want this program to be modified so it can read buffers 

      double room_0 = array_results[0]; // index 0
      double room_1 = array_results[1]; // index 1
      double room_2 = array_results[2]; // index 2
      double room_3 = array_results[3]; // index 3

for each symbol existed in marketwatch and when i print

Print(symbolsList[j], array_results[0]);

I get results like

Symbol_1 buffer_for_Symbol_1 for PERIOD_1

Symbol_2 buffer_for_Symbol_2 for PERIOD_2

like this
