Trade history MQL4 vs MQl5

Hello everyone,

I'm trying to convert some part of my MQL4 code to MQL5 code.

After reading the documentation, I still have trouble understanding some things. Can you tell if the following code do the same things

MQL4 version:

void historyMQL4(){
   for(int z=OrdersHistoryTotal(); z>= 0; z--)
   {
      if(OrderSelect(z,SELECT_BY_POS,MODE_HISTORY)){
      double op      = OrderProfit();
      datetime oct   = OrderCloseTime();
      double oop     = OrderOpenPrice();
      double otp     = OrderTakeProfit();
      double osl     = OrderStopLoss();
      int ot         = OrderType();
      string os      = OrderSymbol();
      double ol      = OrderLots();
      
      // next code
         }
      }
   }
}

MQL5 version

void historyMQL5()
{
   if (HistorySelect(0, INT_MAX))
   {
      int total=HistoryDealsTotal();
      for (int i = total - 1; i >= 0; i--)
      {
         ulong Ticket = HistoryDealGetTicket(i);
         if (HistoryDealGetInteger(Ticket, DEAL_ENTRY) == DEAL_ENTRY_OUT)
         {
            double op   = HistoryDealGetDouble(dticket,DEAL_PROFIT);
            datetime oct= (datetime)HistoryDealGetInteger(Ticket, DEAL_TIME);
            double oop  = HistoryDealGetDouble(Ticket, DEAL_PRICE);        
            int ot      = HistoryDealGetInteger(Ticket, DEAL_TYPE) == DEAL_TYPE_BUY  ? DEAL_TYPE_SELL : DEAL_TYPE_BUY;
            string os   = HistoryDealGetString(Ticket, DEAL_SYMBOL);
            double ol   = HistoryDealGetDouble(Ticket,DEAL_VOLUME);
            
            const ulong OrderTicket = HistoryDealGetInteger(Ticket, DEAL_ORDER);
            if (OpenTicket > 0)
            {
               double oop = HistoryOrderGetDouble(OrderTicket, ORDER_PRICE_OPEN);
               double osl = HistoryOrderGetDouble(deal_order, ORDER_SL);
               double otp = HistoryOrderGetDouble(deal_order, ORDER_TP);
            }
            else continue;            
         }
         // next code
      }
   }
}

I don't want to use a library? I want to do it with native MQL5.

Happy new year

cheers
