...Если поставить малый размер входному параметру profit, то депо будет слито очень быстро.

Can you tell me how to determine the optimum size of the profit parameter?

Maybe depending on the size of the deposit? But how exactly?

By the way, in less than 24 hours on the demo +10% of the deposit.

there is an error in the code.

We need to correct a piece of it:

   double secondlots = 0;

   for (int i = 0; i < total; i++) {
      OrderSelect( i, SELECT_BY_POS, MODE_TRADES);
      if (OrderSymbol() == Symbol()) {
         currentticket = OrderTicket();
         currentprofit = currentprofit + OrderProfit();
         currenttype = OrderType();
      }
      if (OrderSymbol() == seconds_instrument) {
         secondticket = OrderTicket();
         secondtype = OrderType();
         currentprofit = currentprofit + OrderProfit();
         secondlots = OrderLots();
      }
   }


   if (( secondticket < 0) && ( currentticket >= 0)) {
      Comment("Try close positon for " + Symbol());
      if ( currenttype == OP_BUY) {
         if (OrderClose( currentticket, lots, Bid, 2, Blue)) {
            openbarspriceonly = true;
         }
         return(0);
      } else {
         if (OrderClose( currentticket, lots, Ask, 2, Red)) {
            openbarspriceonly = true;
         }
         return(0);
      }
   }

to

   double currentlots = 0;
   double secondlots = 0;

   for (int i = 0; i < total; i++) {
      OrderSelect( i, SELECT_BY_POS, MODE_TRADES);
      if (OrderSymbol() == Symbol()) {
         currentticket = OrderTicket();
         currentprofit = currentprofit + OrderProfit();
         currenttype = OrderType();
         currentlots = OrderLots();
      }
      if (OrderSymbol() == seconds_instrument) {
         secondticket = OrderTicket();
         secondtype = OrderType();
         currentprofit = currentprofit + OrderProfit();
         secondlots = OrderLots();
      }
   }


   if (( secondticket < 0) && ( currentticket >= 0)) {
      Comment("Try close positon for " + Symbol());
      if ( currenttype == OP_BUY) {
         if (OrderClose( currentticket, currentlots, Bid, 2, Blue)) {
            openbarspriceonly = true;
         }
         return(0);
      } else {
         if (OrderClose( currentticket, currentlots, Ask, 2, Red)) {
            openbarspriceonly = true;
         }
         return(0);
      }
   }
