Here you are

double last_deal_volume(const string symbol,const int magicnumber)
  {
// --- determine the time intervals of the required trading history
   datetime end=TimeCurrent();                 // current server time
   datetime start=end-PeriodSeconds(PERIOD_H1) *Hours_Order_lookback;// set the beginning time to 24 hours ago

//--- request in the cache of the program the needed interval of the trading history
   HistorySelect(start,end);
//--- obtain the number of deals in the history
   int deals=HistoryDealsTotal();

   int returns=0;
   double profit=0;
   double loss=0;
   double deal_volume=0;
//--- scan through all of the deals in the history
   if(deals>0)
     {
      for(int i=deals-1;i<deals;i++)
         //+------------------------------------------------------------------+
         //|                                                                  |
         //+------------------------------------------------------------------+
        {
         //--- obtain the ticket of the deals by its index in the list
         ulong deal_ticket=HistoryDealGetTicket(i);
         if(deal_ticket>0) // obtain into the cache the deal, and work with it
           {
            string deal_symbol=HistoryDealGetString(deal_ticket,DEAL_SYMBOL);
            ulong time=HistoryDealGetInteger(deal_ticket,DEAL_TIME);
            ulong order               =HistoryDealGetInteger(deal_ticket,DEAL_ORDER);
            long order_magic          =HistoryDealGetInteger(deal_ticket,DEAL_MAGIC);
            long pos_ID               =HistoryDealGetInteger(deal_ticket,DEAL_POSITION_ID);


            //--- process the deals with the indicated DEAL_MAGIC
            if(order_magic==magicnumber && deal_symbol==symbol)
              {
               deal_volume=HistoryDealGetDouble(deal_ticket,DEAL_VOLUME);
              }

            //--- calculate the losses and profits with a fixed results

           }
         else // unsuccessful attempt to obtain a deal
           {
            PrintFormat("We couldn't select a deal, with the index %d. Error %d",
                        i,GetLastError());
           }
        }
     }
//--- output the results of the calculations
   return(deal_volume);
  }

      for(int i=deals-1;i<deals;i++)

That loop will only process one deal.
