How to take only one action on lots per condition???

1. Play video	Please edit your post. For large amounts of code, attach it.

   ---

2. You can't use OrderLots()/2 because that is not a multiple of LotStep, and you can't close or have remaining less than MinLot. See my code
   
3. You are only checking if price may trigger a partial close. You aren't checking if you have already done it.
   • Set a flag in persistent storage (files, global variables w/ flush)
   • I move SL to BE+1 before the partial close. That way I know that I already did it.
   • Open two orders.
     

Sorry for number 1

2 and 3 still complicated for me

What's the meaning of BE+1 

can't handle it 

Q: What's the meaning of BE+1 ?

A: Breakeven + 1

thanks deysmacro

  void PartialClose()
{  
   double Lotstep = MarketInfo(Symbol(), MODE_LOTSTEP);
   int x = 0; if(Lotstep == 0.01) x = 2; else x = 1;
    
    for(int i = OrdersTotal()-1; i >= 0; i--){
   if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)==false)continue;
   if( Magic == OrderMagicNumber() )
 {
int Tk=100;
double LOTS = OrderLots();
double Dividelot = NormalizeDouble(LOTS * 0.5, x);
     
         if(OrderType() == OP_BUY){
            if(Bid > OrderOpenPrice()+(Tk*Point)){
               OrderClose(OrderTicket(), Dividelot*2, Bid, 3, Red);
            }
         }
         if(OrderType() == OP_SELL){
            if(Ask< OrderOpenPrice()-(Tk*Point)){
               OrderClose(OrderTicket(),Dividelot*2, Ask, 3, Red);
            }
         }
      }
   }

}
 

any help please to solve this problem , still can't handle it

You need to do something like this as suggested by WHRoeder

         if(OrderType() == OP_BUY && OrderStopLoss()<OrderOpenPrice()){
            if(Bid > OrderOpenPrice()+(Tk*Point)){
               {
               OrderModify(OrderTicket(),OrderOpenPrice(),OrderStopLoss()+Point,OrderTakeProfit(),0,clrNONE );
               OrderClose(OrderTicket(), Dividelot*2, Bid, 3, Red);
               }
            }
         }

 Not tested and checking success of OrderModify and OrderClose required

  void PartialClose()
{  
   double Lotstep = MarketInfo(Symbol(), MODE_LOTSTEP);
   int x = 0; if(Lotstep == 0.01) x = 2; else x = 1;
    
    for(int i = OrdersTotal()-1; i >= 0; i--){
   if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES))continue;
   if( Magic == OrderMagicNumber() )
 {
int Tk=100;
double LOTS = OrderLots();
double Dividelot = NormalizeDouble(LOTS * 0.5, x);
     
         if(OrderType() == OP_BUY&& OrderStopLoss()<OrderOpenPrice()){
            if(Bid > OrderOpenPrice()+(Tk*Point)){
            OrderModify(OrderTicket(),OrderOpenPrice(),OrderStopLoss()+50*Point,0,0,clrNONE );
               OrderClose(OrderTicket(), Dividelot*2, Bid, 3, Red);
            }
         }
         if(OrderType() == OP_SELL&& OrderStopLoss()>OrderOpenPrice()){
          
            if(Ask< OrderOpenPrice()-(Tk*Point)){
               OrderModify(OrderTicket(),OrderOpenPrice(),OrderStopLoss()-50*Point,0,0,clrNONE );
               OrderClose(OrderTicket(),Dividelot*2, Ask, 3, Red);
            }
         }
      }
   }

}
 

What do you mean "it still doesn't work"?

What doesn't work?
