Support Needed - Moving Average EA

Moving Average EA

Logic:

- Always in market and holding trade based on prevailing trend.

- Check for signal once per new bar. ** I think this is not working. (See attached picture of backtest)

- Signal triggered if Closing Price of Previous Bar crosses the 5 EMA in the opposite direction.

- Action taken upon signal:

1. Close previous open trade,

2. Open new trade in opposite direction.

The EA:

extern int       MA_Period=5;
extern int       MA_Method=1;
extern double    Lots=0.1;
int init() {return(0);}
int deinit(){return(0);}
int start()
  {
   int BarOpen = 0;           //Run Once Per Bar
   if (Open[0] != BarOpen)
   {
      BarOpen=Open[0];
      
      if (Close[2]<iMA(NULL,0,MA_Period,0,MA_Method,0,2)&&Close[1]>iMA(NULL,0,MA_Period,0,MA_Method,0,1)) // Uptrend
      {
        int total = OrdersTotal(); //Close Short Positions
        for(int i=total-1;i>=0;i--)
         {
            OrderSelect(i, SELECT_BY_POS);
            if(OrderSymbol()==Symbol()&& OrderType()==1)
            {bool result = OrderClose( OrderTicket(), OrderLots(), MarketInfo(OrderSymbol(), MODE_ASK), 5, Red );}
         }
        OrderSend (Symbol(),0,Lots,Ask,3,NULL,NULL,NULL,0,0,Green); // Open Long Position
      }
      
      if (Close[2]>iMA(NULL,0,MA_Period,0,MA_Method,0,2)&&Close[1]<iMA(NULL,0,MA_Period,0,MA_Method,0,1)) //Downtrend
      {
        total = OrdersTotal(); //Close Long Positions
        for(i=total-1;i>=0;i--)
         {
            OrderSelect(i, SELECT_BY_POS);
            if(OrderSymbol()==Symbol()&& OrderType()==0)
            {result = OrderClose( OrderTicket(), OrderLots(), MarketInfo(OrderSymbol(), MODE_BID), 5, Red );}
         }
         OrderSend (Symbol(),0,Lots,Bid,3,NULL,NULL,NULL,0,0,Green); //Open Short
      }
      
   return(0);
   }
  }

My Problem:

1. EA opening multiple positions (too many) in the same bar.

Can someone please point out my mistake ?

I'm using the fact that each bar opening price is different to differentiate one bar from another.

Thanks.
