[amando]

i try to change my mode from the netting mode to the Hedge mode, so i want to selct the histroy order with MagicNumber and Symbol,

i use follofing code

 

double last_deal_volume(const string symbol, const int magic)
  {
  double deal_price;
  double deal_volume;
  double deal_profit;
    
// --- time interval of the trade history needed
   datetime end=TimeCurrent();                 // current server time
   datetime start=end-PeriodSeconds(PERIOD_D1)*Days_Order_loockback;// decrease 1 day
//--- request of trade history needed into the cache of MQL5 program
   HistorySelect(start,end);
//--- get total number of deals in the history
   int deals=HistoryDealsTotal();
//--- get ticket of the deal with the last index in the list
   ulong deal_ticket=HistoryDealGetTicket(deals-1);
   if(deal_ticket>0) // deal has been selected, let's proceed ot
     {

      //--- ticket of the order, opened the deal
      ulong  order=HistoryDealGetInteger(deal_ticket,DEAL_ORDER);
      string deal_symbol=PositionGetString(POSITION_SYMBOL); 
      long   order_magic=HistoryDealGetInteger(deal_ticket,DEAL_MAGIC);
      long   pos_ID=HistoryDealGetInteger(deal_ticket,DEAL_POSITION_ID);
      
             deal_price=HistoryDealGetDouble(deal_ticket,DEAL_PRICE);
             deal_volume=HistoryDealGetDouble(deal_ticket,DEAL_VOLUME);
             deal_profit=HistoryDealGetDouble(deal_ticket,DEAL_PROFIT);
    //  PrintFormat("Deal: #%d opened by order: #%d with ORDER_MAGIC: %d was in position: #%d price: #%f volume: #%f",
    //              deals-1,order,order_magic,pos_ID,deal_price,deal_volume);
      
     }
   else              // error in selecting of the deal
     {
     
      PrintFormat("Total number of deals %d, error in selection of the deal"+
                  " with index %d. Error %d",deals,deals-1,GetLastError());
     }
   return(deal_volume);
  }

does anyone have an idea, that i get only the volume for the last trade in with my MagicNumer in the Symbol back?
