CPairedDealInfo Class – library MetaTrader 5

CPairedDealInfo is a class to reconstruct closed trades (paired in/out deals) from history sorted by close time.

The class has a similar interface to CDealInfo class of the standard library.

class CPairedDealInfo : public CObject
  {
public:
                     CPairedDealInfo(void);
                    ~CPairedDealInfo(void);
   //--- methods of access to protected data
   ulong             TicketOpen(void)       const { return(m_curr_ticket_in); }
   ulong             TicketClose(void)      const { return(m_curr_ticket_out); }
   //--- fast access methods to the integer deal properties
   datetime          TimeOpen(void) const;
   ulong             TimeOpenMsc(void) const;
   datetime          TimeClose(void) const;
   ulong             TimeCloseMsc(void) const;
   ENUM_DEAL_TYPE    DealType(void) const;
   string            TypeDescription(void) const;
   long              Magic(void) const;
   long              PositionId(void) const;
   long              OrderOpen(void) const;
   long              OrderClose(void) const;
   ENUM_DEAL_REASON  OpenReason(void) const;
   ENUM_DEAL_REASON  CloseReason(void) const;
   //--- fast access methods to the double deal properties
   double            Volume(void) const;
   double            PriceOpen(void) const;
   double            StopLoss(void) const;
   double            TakeProfit(void) const;
   double            PriceClose(void) const;
   double            Commission(void) const;
   double            Swap(void) const;
   double            Profit(void) const;
   //--- fast access methods to the string deal properties
   string            Symbol(void) const;
   string            OpenComment(void) const;
   string            CloseComment(void) const;
   string            OpenReasonDescription(void) const;
   string            CloseReasonDescription(void) const;
   //--- info methods
   string            FormatAction(string &str,const uint action) const;
   string            FormatReason(string &str,const uint reason) const;
   //--- method for select deals
   bool              HistorySelect(datetime from_date,datetime to_date);
   int               Total(void) const;
   bool              SelectByTicket(const ulong ticket);
   bool              SelectByIndex(const int index);
  };

Here is a sample code showing how to use the class in your code

      return;
