What is this operator or function or variable, in short, what is it?
How to enter it, so that the compiler doesn't throw an error:

variables have to be declared before they can be used.

Sort of here https://docs.mql4.com/ru/constants/errors

The ErrorDescription() function defined in stdlib.mqh should be used to output text messages.

#include <stderror.mqh>
#include <stdlib.mqh>

Already done, but thanks anyway. :)

What are the reasons for the optimizer to really slow down? The first 2 runs take a few seconds, then it's like a jam, after 40 min one more run is added

Where a run goes fast is a fast drain. :)))

Maybe it skips useless variants with negative balance, but it takes time for them too.

In the currency of the deposit.

Like this?

double FindRightLot (int otype) // функция поиска лота, необходимого для выхода из просадки после 
                               //закрытия сетки ордеров
{
  double Loss=0; double TotalLoss=0; double LotIneed=0; double TL=0;
  for (int i = OrdersTotal()-1; i>0; i--)
  {
    if (OrderSelect(i, SELECT_BY_POS,MODE_TRADES))
    {
       if (OrderSymbol()==Symbol() && OrderMagicNumber()==Magic && OrderType() == otype)
       {
         if (otype == OP_BUY)
         {
           if (OrderProfit()<0)
           {
              Loss = OrderProfit();
              TotalLoss +=Loss;
              TL = MathAbs(TotalLoss);
              LotIneed = NormalizeDouble (TL / TakeProfit,2);
           }
         }
           
       
         else if (otype == OP_SELL)
         {
           if (OrderProfit()<0)
           {
              Loss = OrderProfit();
              TotalLoss +=Loss;
              TL = MathAbs(TotalLoss);
              LotIneed = NormalizeDouble (TL / TakeProfit,2);
           }
         }
       }
     }
   }
   return (LotIneed);

Another question, the tester shows error 138 (ERR_REQUOTE) what does it mean?

It means that there are no requotes in the tester. It means that there is an error in the trade order. Most likely, you are trying to open the market one as a pending one.
