           }
        }
     }
  }


if(OrderStatus==1)
        {
         ReSetProfitBalance();
         OrderGroupA();         
         MaxNum=ArrayMaximum(BuyOrderPrice,0,WHOLE_ARRAY);
         int MinNum=ArraySize(BuyOrderPrice);
         
         if((TP_A - xbid) < 100*_Point) 
         {
          xF.coverbuyspecific_order(Symbol(),POSITION_TYPE_BUY,"Buy_A"+string(MaxNum)+1,MaxNum);
          xF.coverbuyspecific_order(Symbol(),POSITION_TYPE_BUY,"Buy_A"+string(MinNum)+1,MinNum);
          ArrayRemove(BuyOrderPrice,0,WHOLE_ARRAY);
         }


Hello,I would like to ask about how to delete Array Info after order closed.

The situtation is when my program close order by using coverbuyspecific_order function and arrayremove immediately, however closed order info still in BuyOrderPrice Array and the array serial changed as like as picture show.

Can anybody help me? thanks a lot!
