int start()                                  // Special function start()
  {                                          // Opening BUY
   OrderSend(Symbol(),OP_BUY,0.1,Ask,3,Bid-15*Point,Bid+15*Point);
   return(0); // Exit start()
  }

Next time, please post on the Russian language forum

OrderSend returns -1 if it is not successful, you should code to check the error if this happends
