Good people, please advise me, I need a CODE to implement TrailingStop!?

The ones I found online don't work (crawling backwards and forwards)

Trying to implement a simple reversal. When a stop position is reached --> open the opposite position. I can't get it to open opposite position once and not open anything else. Please advise.

Роман 2010.11.02 17:24 #9449

I have it implemented in the following way - this is a condition - if the previous position closed with a loss, then opening the opposite one... If you need to open the opposite position exactly when the stop loss of the previous position is reached, then Kim Igor Vladimirovich has a function at http://www.kimiv.ru/ that determines exactly how to close the order at the stop loss. So, when you connect this function, you should prescribe the condition if the pose was closed when the stop loss was reached. If it was, you should open another one.

PS: Just remembered, this closing fi code for a pose at stop loss was posted on this thread a few pages before... Have a look.

//---Поиск последнего отработавшего ордера для открытия очередной позиции ---
   
   for (orderIndex = (OrdersHistoryTotal() - 1); orderIndex >= 0; orderIndex--)
   {   
      if (!OrderSelect(orderIndex, SELECT_BY_POS, MODE_HISTORY))
      {
         Print("Ошибка при доступе к исторической базе (",GetLastError(),")");
         continue;
      }
   
      if ((OrderSymbol() != Symbol()) || (OrderMagicNumber() != MagicNumber))
      {
         continue;
      }
      
        
   //-------------------------Принимаем в расчет только ордер, закрытый недавно-----------------------
         
      if (OrderCloseTime() >= iTime(NULL, 0, 1))
      {
         int lastType = OrderType();
         double lastLots = OrderLots();
         double lastProfit = OrderProfit() + OrderSwap();
         
        // Print ("lastProfit = ", NormalizeDouble(lastProfit, 1));
         
       
         
         // Анализ только что закрывшегося ордера
      
         if (lastProfit < 0.0)
         {
  //---Ордер закрылся с убытком открываемся в ОБРАТНОМ направлении
                           
           
 // ---------НОРМАЛИЗУЕМ НОВЫЕ РАСЧЕТНЫЕ ЛОТЫ И ОТКРЫВАЕМ ОЧЕРЕДНУЮ ПОЗИЦИЮ...            
    
  // -----если предыдущий ордер был бай, то открываем очередной ордер   
            lots = NormalizeLots(lots);
            if (lastType == OP_SELL)  OrderSend(Symbol(), OP_BUY, lots,...);
                          
            if (lastType == OP_BUY)   OrderSend(Symbol(), OP_SELL, lots, ...);

       }

Trying to implement a simple reversal. When a stop position is reached --> open the opposite position. I can't get it to open opposite position once and not open anything else. Please advise.

What if on level of stop simply put the pending order? Would it not work that way?
