No, the last record of trading activity is in the second log.

And this is correct in terms of priority:

Here I have reverted to the option without prints and again there is one position left after execution. It turns out that you need to hold some kind of pause after the trades are executed. Man, what a crutch.

Well, who's going to update it? ))

but when there is an open position - the script closes it and does not do anything else

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

also if i try to open a position the script closes it instantly

[Dmitry Fedoseev]

fxsaber:

managed to write IsSynchronized(). The code is a bit heavy. I haven't decided yet in what form to post it.

How does it work? It is sort of found but sort of absent? What is the gist or principle of the solution?

[Ihor Herasko]

SanAlex:

But when there is an open position, the script closes it and does nothing else.

Not all servers will reproduce the opening of two positions. In your case, it is the third side (one side - two positions, the other - one position).

Ihor Herasko:

And that's about right in terms of sequencing:

And it's all right here in terms of ordering:

2021.05.05 10:32:35.896 Trades  '160122203': market buy 0.01 EURUSD placed for execution
2021.05.05 10:32:35.931 Trades  '160122203': order #2249869869 buy 0.01 / 0.01 EURUSD at market done in 81.962 ms

The highlighted lines confirm the sequence.

PositionsTotal = 1 - sends an order to close.

Then PositionsTotal = 2 and the order from step 1 is closed.

The closing takes place after the script execution is completed. Print-cache is a bit distorted.

Dmitry Fedoseev:

How so? It's sort of found but sort of not there?

I haven't gotten around to posting it yet. I will post it within 24 hours.

What is the essence or principle of the solution?

It analyzes the correspondence of the trading history to the current trading environment. In this case, there are no slows.

It also checks Result.order.

As a result, the use is as follows: IsSync() returns false - the trading environment in the Terminal is crooked, otherwise we can proceed as usual.

Ihor Herasko:

Added prints. Now two positions remain, as expected:

Result:

Add Trade.ResultRetcodeDescription()

#include <Trade\Trade.mqh>

void OnStart()
{
  CTrade Trade;
  
  while (!IsStopped() && (PositionsTotal() <= 1)) // Закончим, когда появится более одной позиции.
    if (PositionsTotal() == 1)
    {
      Trade.PositionClose(PositionGetTicket(0)); // Если есть позиция - закрываем.
      Print("Закрытие, т. к. PositionsTotal() равно 1");
    }
    else if (!OrdersTotal())
    {
      printf("Перед открытием. PositionsTotal: %d, OrdersTotal: %d", PositionsTotal(), OrdersTotal());
      Trade.Buy(0.01); // Если нет позиции и ордера - открываем позицию.
      Print(Trade.ResultRetcodeDescription());
      printf("После открытия. PositionsTotal: %d, OrdersTotal: %d", PositionsTotal(), OrdersTotal());
    }
    
  Print("Выход. PostionsTotal: ", PositionsTotal());
}

Also ResultDeal / ResultOrder / ResultComment and Order.State

Surely there will be an answer there

Done:

#define  PRINT(A) Print(#A + " = " + (string)(A))

#include <Trade\Trade.mqh>

void OnStart()
{
  CTrade Trade;
  
  while (!IsStopped() && (PositionsTotal() <= 1)) // Закончим, когда появится более одной позиции.
    if (PositionsTotal() == 1)
    {
      Trade.PositionClose(PositionGetTicket(0)); // Если есть позиция - закрываем.
      Print("Закрытие, т. к. PositionsTotal() равно 1");
    }
    else if (!OrdersTotal())
    {
      printf("Перед открытием. PositionsTotal: %d, OrdersTotal: %d", PositionsTotal(), OrdersTotal());
      Trade.Buy(0.01); // Если нет позиции и ордера - открываем позицию.
      PRINT(Trade.ResultRetcodeDescription());
      PRINT(Trade.ResultDeal());
      PRINT(Trade.ResultOrder());
      PRINT(Trade.ResultComment());
      printf("После открытия. PositionsTotal: %d, OrdersTotal: %d", PositionsTotal(), OrdersTotal());
    }
    
  Print("Выход. PostionsTotal: ", PositionsTotal());
}

This is definitely not the case as the condition for sending a market order to open a position is PositionsTotal == OrdersTotal == 0.
