If after - all ok )

Question - how do I know the commission of a position in MQL5?

I did it in MQL4 like this

There is no commission in MQL5.

I looked in the order properties, and there is no commission as well. What should I do?

It is somewhere in the properties of a symbol

You should look in the deal properties. HistoryDealGetDouble(ticket, DEAL_COMMISSION);

The library will return the correct value when calling

OrderCommission()

The source code shows the following

   static ulong GetPositionDealIn(const ulong HistoryTicket=0)
     {
      ulong Ticket=0;

      if((HistoryTicket==0) ? ::HistorySelectByPosition(::PositionGetInteger(POSITION_TICKET)) : ::HistorySelectByPosition(HistoryTicket))
        {
         const int Total=::HistoryDealsTotal();

         for(int i=0; i<Total; i++)
           {
            const ulong TicketDeal=::HistoryDealGetTicket(i);

            if(TicketDeal>0)
               if((ENUM_DEAL_ENTRY)::HistoryDealGetInteger(TicketDeal,DEAL_ENTRY)==DEAL_ENTRY_IN)
                 {
                  Ticket=TicketDeal;

                  break;
                 }
           }
        }

      return(Ticket);
     }

   static double GetPositionCommission(void)
     {
      double Commission=::PositionGetDouble(POSITION_COMMISSION);

      // На случай, если POSITION_COMMISSION не работает
      if(Commission==0)
        {
         const ulong Ticket=MT4ORDERS::GetPositionDealIn();

         if(Ticket>0)
           {
            const double LotsIn=::HistoryDealGetDouble(Ticket,DEAL_VOLUME);

            if(LotsIn>0)
               Commission=::HistoryDealGetDouble(Ticket,DEAL_COMMISSION)*::PositionGetDouble(POSITION_VOLUME)/LotsIn;
           }
        }

      return(Commission);
     }

How about this... There is no POSITION_COMISSION property in the documentation, only DEAL_COMISSION in the transaction properties.

Thanks, I'll know another inaccuracy in the documentation.

[Dmitry Fedoseev]

Then how is the commission taken into account? It is not added to the profit of the position? Does it affect the balance immediately after the position is opened?

Yes.

In the source code it's like this

Do you have the defines commented out at the end there, is that how it should be? One more thing. I will be making a video reel on my blog at YouTube translating from MQL4 to MQL5. Do you mind if I translate your library too? The link to kodobase, of course.

And there is no such property in documentation, but it compiles ) Here is everything that is in the terminal's help.

POSITION_VOLUME	Position volume	double
POSITION_PRICE_OPEN	Position price	double
POSITION_SL	Stop loss level for open position	double
POSITION_TP	Take Profit level for open position	double
POSITION_PRICE_CURRENT	Current price for the symbol	double
POSITION_SWAP	Accumulated swap	double
POSITION_PROFIT	Current profit	double

Alexey Viktorov:
Look in the properties of the transaction. HistoryDealGetDouble(ticket, DEAL_COMMISSION);

So, the commission can be found out only after the position is closed? But it is taken at opening, at least on ECN accounts in alp and robot. This is not good.
