Tried it, still can't fool the brain...there's probably no such thing, ok, but is writing to a specialist a long one or not?

If your Expert Advisor is losing, it does not mean that if you do the opposite, you will make a profit)))

From my experience, I can tell you that you can take a profitable EA, turn it upside down, and it will still be profitable. If you take a losing EA and invert it, it will still be losing. This is the paradox

So there is no advisor, I'm nowhere has not written that trades an advisor, all my hands, I want to trade as usual, but only that the script or expert open transaction opposite to mine, ie mine would not open that at all, but the opposite. If I have not done it or it is difficult to do, tell me, I will understand. I just asked yes, yes, no, no.

Yes, I know about this paradox, I searched the forum for what I want and found a lot of such proposals and studies, but this is not what I want.

You're doing it with your hands. Well, you've got your hands in the air. You don't have to do everything the other way around. Why, say, instead of "open" close, if nothing is open. For example, you think you have to open buy, then open sell, vice versa. Good luck, i.e. a lot of g...!

I appeal to you as a programming professional, tell me if such a script or expert is difficult to write or not? (the rest of the statement is unnecessary - all people are different)

Unfortunately, I couldn't find it. There was something similar, but not the same...

Will this code work?

double CalculateProfit_last() {//прибыль от последенй сделки
   double Profit = 0;
   int cnt;
   if(OrdersTotal()!=0)
   {
   cnt = OrdersTotal() - 1;
      OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
      if (OrderSymbol() == Symbol() && OrderMagicNumber() == MagicNumber)
         if (OrderType() == OP_BUY || OrderType() == OP_SELL) Profit = OrderProfit();
    }
    Profit=0.0;
   Print(Profit);
   return (Profit);
}
