OrderSend from the documentation

Returned value

Returns number of the ticket assigned to the order by the trade server or -1 if it fails. To get additional error information, one has to call the GetLastError() function.

   int ticket=OrderSend(Symbol(),OP_BUY,1,price,3,stoploss,takeprofit,"My order",16384,0,clrGreen); 
   if(ticket<0) 
     { 
      Print("OrderSend failed with error #",GetLastError()); 
     } 
   else 
      Print("OrderSend placed successfully");
