You still don't get it, do you? I tried to explain why your condition is always true and the order closes.

Got it, got it, further reasoning was personal. It slipped out.

Got it, got it, the reasoning was personal. It's gone.

Calculate profit in pips (it's easy) and set x value in pips too. As a result, everything will be in pips. Set x less than the spread (for your example more). Then everything will work correctly.

You could do it that way, and you could do a virtual sl. But I haven't done that yet.

The main thing is to get a signal to close the order when it reaches -x

Post the close function and what "-x" is

hello

found a function that keeps track of the current price value

bool  SymbolInfoTick(
   string    symbol,     // символ
   MqlTick&  tick        // ссылка на структуру
   );

question:

how to specify the current symbol ?

it is not clear what isMqlTick&?

The handbook states that it is a structure for storing the latest prices for a symbol. It is intended to quickly obtain the most requested information on current prices.

But in the usage example it is stated:

void OnTick()
  {
   MqlTick last_tick;
//---
   if(SymbolInfoTick(Symbol(),last_tick))
     {
      Print(last_tick.time,": Bid = ",last_tick.bid,
            " Ask = ",last_tick.ask,"  Volume = ",last_tick.volume);
     }
   else Print("SymbolInfoTick() failed, error = ",GetLastError());
//---
  }

That is, the function that refers to the MqlTick structure is itself inside the structure.

How can this be?

It is a structure

MqlTick last_tick;

and this is a reference to it by a certain symbol

if(SymbolInfoTick(Symbol(),last_tick))

It is a structure

and this is a reference to it by a specific symbol

... and then there is no example of reading the structure. Judging from the first question, the person will not understand it either.

There is nothing else. And x is a negative profit value on an open order.

The close function is at which condition should an order be closed?

Is x a condition?

Then what did I show?

Or if you don't mind, write in more detail what is needed.

In any case, thank you!

How can it be?

The SymbolInfoTick function writes tick data into a specialMqlTick structure, from the fields of which they can be obtained.

struct MqlTick
  {
   datetime     time;          // Время последнего обновления цен
   double       bid;           // Текущая цена Bid
   double       ask;           // Текущая цена Ask
   double       last;          // Текущая цена последней сделки (Last)
   ulong        volume;        // Объем для текущей цены Last
   long         time_msc;      // Время последнего обновления цен в миллисекундах
   uint         flags;         // Флаги тиков
   double       volume_real;   // Объем для текущей цены Last c повышенной точностью
  };
