This is a question from a beginner) condition in the code for an example, help please.

How to make a message at the true condition was output once, that is price>ma output one message (and not multiply), I think you know what I mean.

How to properly prescribe the counter?

if(Work==false) // Критическая ошибка
     {
      if(AlertWork==false)   // Если Алерта еще не было
        {  Alert("Критическая ошибка. Эксперт не работает."); AlertWork=true; }
      return;
     }

How so, but you have not once need to display the alert, respectively, the flag will have to reset.

I'm confused about graphical objects, I can't figure out how to get X Y coordinates High[0] in pixels from CORNER_RIGHT_UPPER? What would be the functions to calculate int X and int Y?

Somehow, but you have to display the alert more than once, so the flag will have to be reset.

   if(sizeBar && maxmin)
     {
      
                   while(true)
                   {
                         int ticket = OrderSend(Symbol(), OP_BUY, 0.01, Ask, 5, sl, tp);
                         if(ticket>0) break;                        
                   }      
             
     }

I still don't understand

Suppose there is a condition for opening a position, say the price should be above the wrist and a Buy order is opened.

This condition will be true over a long time and at each iteration an order will be opened by this code

How should I make one order be opened by this condition and that will be it?

I don't get it.

Let's assume there is a condition for opening a position, let's assume the price should be higher than the wrist and a buy order will be opened.

This condition will be true over a long time and at each iteration an order will be opened by this code

How should I make one order be opened by this condition and that will be it?

If the open order condition is true and the open order flag is false, then open an order and set the open order flag to true.
