Vladimir Pastushak:
How do I understand the account type programmatically? Hedge or netting? 
   if(m_account.MarginMode()!=ACCOUNT_MARGIN_MODE_RETAIL_HEDGING)
     {
      Alert("Only Hedging!");
      return(INIT_FAILED);
     }
 

Or like this

AccountInfoSample

   m_label_info[3].Description(m_account.MarginModeDescription());

Please help me find an EA (script) which either puts a grid of virtual pending orders with specified parameters, or opens orders (one by one) in a specified direction with a specified take.
 

Please tell me where the error lies:

      for(int s=OrdersTotal()-1; s>=0; s--)          
         {
           if(o_orderInfo.SelectByIndex(s)) 
           if(o_orderInfo.OrderType()==ORDER_TYPE_SELL_STOP)
             {                 
               count_sell_stop++;
             }
         }  

      for(int s1=PositionsTotal()-1; s1>=0; s1--)          
         {
           if(o_orderInfo.SelectByIndex(s1)) 
           if(o_orderInfo.OrderType()==ORDER_TYPE_SELL)
             {                 
               count_sell++;
             }
         }  
         
      if(count_sell == 0 && count_sell_stop == 0)
         {
            sellstop_req3.action       = TRADE_ACTION_PENDING;
            sellstop_req3.symbol       = _Symbol;
            sellstop_req3.volume       = NormalizeDouble(lot_v, 2);
            sellstop_req3.price        = SymbolInfoDouble(sellstop_req3.symbol, SYMBOL_ASK) - 100*_Point;
            sellstop_req3.sl           = sellstop_req3.price + 110*_Point;
            sellstop_req3.type         = ORDER_TYPE_SELL_STOP;
            sellstop_req3.type_filling = ORDER_FILLING_RETURN;
            sellstop_req3.expiration   = ORDER_TIME_GTC;
            
            OrderSend(sellstop_req3, sellstop_res3);
         }
SELL_STOP - the orders are calculated, but SELL doesn't want it. According to the algorithm, if there are none, the SELL_STOP order is placed, and if there is at least one of them, the order is not placed.

Please tell me where the error lies:

SELL_STOP - orders are counted, but SELL does not want. According to the algorithm, if there are none, the SELL_STOP order is placed, and if at least one of them is present, no order is placed.

Don't confuse the LOCAL ORDER with the POSITION.

Don't confuse the REMOTE ORDER with the POSITION.

THANK YOU)) Got it...
 
I don't understand what the parameter begin in the second version of onCalculate function is responsible for.
Every time onCalculate function is called, it equals 0.
I was outputting the value of begin via print function.
The reference book says that begin is "where the meaningful data starts from". This doesn't tell me anything.

Look at the open indicator codes from Example.

 
Mikhail Mishanin:

I looked. Always begin = 0.

Here, I pulled a piece of code from AMA indicator

if(begin!=0)

PlotIndexSetInteger(0,PLOT_DRAW_BEGIN,ExtPeriodAMA+begin);


And what should this code tell me if the condition begin!=0 is never true?

 
Can you tell me what to use to count closed orders in the history. I tried it like this:

HistorySelect(0,TimeCurrent());

Alert("Количество ордеров в истории:  ",HistoryOrdersTotal());
It gives out some nonsense in the end, much more than closed orders.
