Good afternoon, Mr. Professionals! I solve all the MQL5 programming basics by solving programming tasks from the book "Programming Tasks" by S.A. Abramov (Programmer's Library) - 1988. I've done another one and am trying to solve it. Made a flowchart. Help a beginner. Can you tell me how to organize transitions? Or give me a link where I can read about transitions. Thank you very much.

Thank you for your feedback. I'm having a hard time with this subject, though. But persistence never fails me. Could you give me a very small example. I apologize for my technical language in programming.

How do I go from a lower point in the programme to an earlier point in the programme.

The question is somewhat abstract.

Read about operators

How do I get from point B to point A? Roughly speaking, I need some kind of prototype go-to operator

There is no such thing. This is not a procedural language. The program here is strictly top-down. And function calls solve everything there are loops, if that. AND OOP)

Got it. Got it. Thanks for the clarification.

Hi

    if(OrderSelect(FindTicketOrder(), SELECT_BY_TICKET,MODE_TRADES)) 
    { 
      if(OrderProfit()<=-x);
        {
         OrderClose(FindTicketOrder(),OrderLots(),OrderClosePrice(),iSlippage,clrPink);
        }
    } 
  else 
    Print("OrderSelect() вернул ошибку - ",GetLastError());

Got a profit order on a ticket, I want to close when it reaches -x.

But I get all orders closed in a row.

Can you tell me how to do this correctly?

Try to do it in this way

 int min_ticket=FindTicketOrder();
    if(OrderSelect(min_ticket, SELECT_BY_TICKET,MODE_TRADES)) 
    { 
      if(OrderProfit()<=-x);
        {
         OrderClose(min_ticket,OrderLots(),OrderClosePrice(),iSlippage,clrPink);
        }
    } 
  else 
    Print("OrderSelect() вернул ошибку - ",GetLastError());

In general, you should develop the whole function to understand what you are doing

//+------------------------------------------------------------------+
void Функция()
  {
   ...твой код, возможные ошибки;
  }
