CTrade.PositionClose()

[DeltaElectronics]

With reference to this page:https://www.mql5.com/en/docs/standardlibrary/tradeclasses/ctrade/ctradepositionclose, I want that once a deal is just closed whit this chunk of code:

int posOpened = PositionsTotal();

   for (int i=0; i<posOpened;i++) {

      ticket = PositionGetTicket(i);

      print("Opened order ticket no.: "+IntegerToString(ticket)+" closed");

      m_trade.PositionClose(ticket);     

   }

I want adeguately catch the closing events in onTradeTransaction() events of my robot;

i.e, referring to it:

void OnTradeTransaction(const MqlTradeTransaction& trans,

                        const MqlTradeRequest& request,

                        const MqlTradeResult& result)

  {

//---

   string   reason;

   long     deal_entry        =0;

   double   deal_profit       =0.0;

   double   deal_volume       =0.0;

   string   deal_symbol       ="";

   long     deal_magic        =0;

   long     deal_reason       =-1;

   long     deal_type         =-1;

   datetime time;

   string   tipo;



   ENUM_TRADE_TRANSACTION_TYPE type=trans.type;

   switch (type) {

      case TRADE_TRANSACTION_DEAL_ADD:

               deal_entry= HistoryDealGetInteger(trans.deal,DEAL_ENTRY);

               deal_profit=HistoryDealGetDouble(trans.deal,DEAL_PROFIT);

               deal_volume=HistoryDealGetDouble(trans.deal,DEAL_VOLUME);

               deal_symbol=HistoryDealGetString(trans.deal,DEAL_SYMBOL);

               deal_magic =HistoryDealGetInteger(trans.deal,DEAL_MAGIC);

               deal_reason=HistoryDealGetInteger(trans.deal,DEAL_REASON);

               deal_type  =HistoryDealGetInteger(trans.deal,DEAL_TYPE); 

           switch(deal_entry) {

      ....

          }

    break;

   }

}

I want to add the code in order to adequately handling such event.
