Multiple Orders in EA - Problem while decrease counters

I have a problem regarding the number of orders that EA can open simultaneously. I set the code as it follows:

sinput string MAXORDERS; // Maximum Number of orders open simultaneously
extern int buys=5; // Number of buys
extern int sells=5; // Number of sell orders opened simultaneously

int gBuyTicket, gSellTicket;

//...

int OnInit()
  {
//---
   double minLot=MarketInfo(_Symbol,MODE_MINLOT); // Check if the input lot is lower than minimum market size
   if(LOTS<minLot) LOTS=minLot;
   MAX_LOSS=-MAX_LOSS;
   if(leverage<1) leverage=1;
   if(buys<1) buys=1;
   if(sells<1) sells=1;

//---
   return(INIT_SUCCEEDED);
  }

//...

void OnTick()
{
if (Volume[0]==1)
{

//...

if(/*TRADE CONDITIONS*/ && countBuy<buys)
        {
         // Open buy order
         gBuyTicket=OrderSend(_Symbol,OP_BUY,LOTS,Ask,slippage,0,TP,"Market Buy Order Opened",MAGIC,0,clrGreen);
         countBuy++;
        }

      // Sell Order Condition
      if(/*TRADE CONDITIONS*/ && countSell<sells)
        {
         // Open sell order
         gSellTicket=OrderSend(_Symbol,OP_SELL,LOTS,Bid,slippage,0,TP,"Market Sell Order Opened",MAGIC,0,clrRed);
         countSell++;
        }

      // Select and Evaluate Orders
      for(int order=OrdersTotal()-1; order>0; order--)
        {
         if(OrderSelect(order,SELECT_BY_POS))
           {
            if(OrderType()==OP_SELL && OrderMagicNumber()==MAGIC)
              {
               if(OrderClosePrice()<=OrderTakeProfit()) countSell--;
               if(/*CLOSING CONDITIONS*/)
                 {
                  // Close Order
                  bool closed=OrderClose(OrderTicket(),OrderLots(),Ask,slippage,clrGreen);
                  if(closed) countSell--;
                 }
              }
            // Close Buy Order if condition is violated
            if(OrderType()==OP_BUY && OrderMagicNumber()==MAGIC)
              {
               if(OrderClosePrice()>=OrderTakeProfit()) countBuy--;
               if(/*CLOSING CONDITIONS*/)
                 {
                  // Close Order
                  bool closed=OrderClose(OrderTicket(),OrderLots(),Bid,slippage,clrRed);
                  if(closed) countBuy--;
                 }
              }
           }
        }
     }
  }

 It works partially because it opens orders but it does not decrease them! So once reached 5 trades for buys and 5 for sells it does not trade anymore. I have commented inside the loop for orders to see if it effectively loops and "order" variable keeps stack on 1. I cannot figure out why. Could you help me? Thanks!
