Problem in closing a trade in MetaTrader5.

Hi,

I am using metatrader 5 and am currently developing an EA for the platform. I hope you guys can help me out with a small problem.

I am using the below code to check if there is a trade placed in my expert advisor and if there is what kind of trade is it (BUY/SELL).

-------------------------------------------------------

FIRST BLOCK

bool Buy_Opened=false;

bool Sell_Opened=false;

if(PositionSelect(_Symbol)==true)
     {
      if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_BUY)
        {
         Buy_Opened=true;
        }
      else if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_SELL)
        {
         Sell_Opened=true;
        }
     }

---------------------------------------------------------

Further, I use the value of Buy_opened/Sell_Opened to send an order in the respective opposite direction (i.e. to close an open trade).

I use the following code to close an open position :

-------------------------------------------------------

SECOND BLOCK

//Buy Order Exit
   if(Buy_Opened)
     {
         mRequest.action=TRADE_ACTION_DEAL;
         mRequest.price=NormalizeDouble(latestPrice.bid,_Digits);
         mRequest.symbol=_Symbol;
         mRequest.volume=Lot;
         mRequest.magic=EAMagic;
         mRequest.type=ORDER_TYPE_SELL;
         mRequest.type_filling=ORDER_FILLING_FOK;
         mRequest.deviation=100;
         OrderSend(mRequest,mResult);
         Buy_Opened=false;
     }

//Sell Order Exit
   if(Sell_Opened)
     {
         mRequest.action=TRADE_ACTION_DEAL;
         mRequest.price=NormalizeDouble(latestPrice.ask,_Digits);
         mRequest.symbol=_Symbol;
         mRequest.volume=Lot;
         mRequest.magic=EAMagic;
         mRequest.type=ORDER_TYPE_BUY;
         mRequest.type_filling=ORDER_FILLING_FOK;
         mRequest.deviation=100;
         OrderSend(mRequest,mResult);
         Sell_Opened=false;
     }

-------------------------------------------------------------

The problem is that when first block is executed Buy_Opened and Sell_Opened become false, after that suppose a sell order is placed and hence sell_opened becomes true now when it enters if(Sell_Opened) in the second block, it executes a buy order in opposite direction,therefore, closing the previous opened trade...Now no trades are opened...Now when First Block is executed again it does not set the values of BUY_OPENED and SELL_OPENED to false instead it sets the value of Buy_Opened(the last order that was used to close the previous order) as true. Can anyone help me with amateur problem of mine? Thank you in advance.
