Partially closed volume order using an EA

[Erman Ardianto]

I've heard that we can't close our trade's volume partially using an EA, is it true?

For example, we enters the market with 2 lots, after certain price we want to close it partially (1 lot), and left the rest 1 lot in the market. I know we can do it manually, but is it possible to do that using an EA?

Thanks

Use OrdersClose(ticket, part_of_Volume,...), for example

for (int i=OrdersTotal()-1;i>=0;i--)
  {
  if (OrderSelect(i,MODE_TRADES))
     {
     if (OrderType==OP_BUY)
        {
        double volume=NormslizeDouble(OrderLots()/2.0,1);
        int ticket=OrderTicket();
        bool res=OrderClose(ticket,volume,Bid,3,Red);
        if (res) Print("Order #",ticket," was partially closed");
        else ("Partially closing of order #",ticket,"is failed!");
        }
     }
  }
