How to call out the ticket number and close it?

New comment
  
for(cnt=0;cnt<total;cnt++)
	{
	OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
	if(OrderType()<=OP_SELL && OrderSymbol()==Symbol())
		{
		if(OrderType()==OP_BUY) // long position is opened
			{
			// should it be closed?
			if(isCrossed == 2)
				{
				OrderClose(OrderTicket(),OrderLots(),Bid,3,Violet);
				// close position
				return(0); // exit
				}

We write Ordersend( ), return the ticket number, e.g. 

ticket=OrderSend(Symbol(),OP_SELL,Lots,Bid,3,0,Bid-TakeProfit*Point,"My EA",12345,0,Red);

 and close with above code, which part of the code that call out the ticket number and close correctly?

as we know 

for(cnt=0;cnt<total;cnt++)

 search all the opened trade, it correctly search the ticket we want?

Don't count up++ when closing orders. Countdown--. https://www.mql5.com/en/forum/139654.

for(int i=OrdersTotal()-1; i>=0; i--)
Always put OrderSelect within an if(){statement}.

You can't rely on retaining the ticket number and using that to select your order . . . what happens if MT4 has to be restarted and you have an open order ?  you will no longer know the ticket number . . .  you have to find it by identifying the correct order.

Use OrderMagicNumber() in your code.

extern int Magic_Number=1234;

...

for (int pos = OrdersTotal() - 1; pos >= 0; pos --)
    {
    if (OrderSelect(SELECT_BY_POS, MODETRADES)
        && OrderSymbol() == Symbol 
        && OrderMagicNumber() == Magic_Number)
        {
        switch (OrderType())
           {
           case OP_BUY  : ...
           case OP_SELL : ...
           ...
           }
         }
      }
        
 
Thanks for the knowledge
 

I try to code as MACD < 0 then sell follow by OrderClose( ) to close the trade.

 

double MACD = iMACD(Symbol(),0,12,26,9,0,0,0);
if(total < 1) //if no trade open
   {
     if (MACD < 0 )
     OrderSend ( Sell );


 for(cnt=OrdersTotal()-1;cnt>=0;cnt--)
     {
     OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
         //if( ! OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES) ) continue;
         if( OrderSymbol() == Symbol()         
            && ( OrderType() == OP_BUY
            ||   OrderType() == OP_SELL ) )    

                 Alert("Job Ticket:" ,OrderTicket(), " found");
                 OrderClose(OrderTicket(),OrderLots(),Bid,3,Blue); // close position
                 return(0); // exit
                }
//----
   return(0);
  }

At OrderClose ( ) I still not give any command e.g " MACD > 0" then close, but the OrderClose ( ) close the trade when MACD > 0.

How this happen? 

 
I cannot see all your codes. From the above it appears that for(loop) runs without any if(){condition}. The if (MACD < 0 ) within your sample seems to only apply to opening orders. After that the EA is free to close orders at will.

1. Your Order Select code is wrong - which obviously you do not read and understand my code

for(cnt=OrdersTotal()-1;cnt>=0;cnt--)
     {
     OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);                   //<<--- wrong
    //if( ! OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES) ) continue; //<<--- correct but why you don't use this

 2. That because you using bar 0 for MACD
