lil_lil:
Thank you.

Or just iHighest() - the latest builds already have it.

[Sile Si]

Ihor Herasko:

In accounts like Netting, a position and a trade are different concepts. You have now shown the selection of a position.

How do youselect the trade included in that position?

long ID=PositionGetInteger(POSITION_IDENTIFIER);

[Alexey Viktorov]

Sile Si:

And howto select the trade included in this position

bool  HistoryDealSelect(
   ulong  ticket     // тикет сделки
   );

[Sile Si]

Alexey Viktorov:

Thank you, there are several deals, so I decided to use HistoryDealGetTicket().

I commented out everything, can you please tell me where I am going wrong. Where am I wrong?

double Aver_Pr_nett()
  {
   double total_price_multiply_volume_sell   = 0.0;
   double total_volume_sell                  = 0.0;
   double net_price_sell_=0.0;
   string symb=_Symbol;
   int    total       =0;  // 
   for(int i=0; i<PositionsTotal(); i++)
     {
      ulong pt=PositionGetTicket(i);//  тикет позиции
      long ID=PositionGetInteger(POSITION_IDENTIFIER);//id позиции
      if(PositionGetString(POSITION_SYMBOL)==symb && //символ позиции
      HistorySelect(PositionGetInteger(POSITION_TIME),TimeCurrent()+60))//промежуток времени для поиска сделок
        {
         total=HistoryDealsTotal();//количество сделок
         
         for(int i=0; i<total; i++)// цикл по всем сделкам
           {
            ulong dt = HistoryDealGetTicket(i);//тикет сделки, возможно нужно использовать HistoryDealSelect()
            long did = HistoryDealGetInteger(dt, DEAL_POSITION_ID);//id сделки
            ENUM_DEAL_ENTRY in_out=HistoryDealGetInteger(dt,DEAL_ENTRY);//
            if(did==pt &&          //id сделки равно тикету позиции
            in_out==DEAL_ENTRY_IN) //сделка открыла позицию либо добавила объём
              {
               if(HistoryDealGetString(dt,DEAL_SYMBOL)==symb)//символ сделки равен текущему графику
                 {//дальше нахожу среднюю цену сделок
                  total_price_multiply_volume_sell+=HistoryDealGetDouble(dt,DEAL_PRICE)*HistoryDealGetDouble(dt,DEAL_VOLUME);
                  total_volume_sell+=HistoryDealGetDouble(dt,DEAL_VOLUME);
                  if(total_price_multiply_volume_sell!=0 && total_volume_sell!=0)
                    {
                    net_price_sell_=total_price_multiply_volume_sell/total_volume_sell;
                    };
                 }
              }
           }
        }

I was very wrong. I gave a wrong reference in a hurry. I was thinking about one thing and chose the wrong one.

Here's the right link.

How do I draw a line on an indicator, e.g. iAO,iDem, by 2 points and get the value of the line at point X ?

[Vladimir Karputov]

Сергей:
How to draw a line on an indicator, e.g. iAO,iDem, by 2 points and get the line value at point X ?

Each indicator is drawn either in the main window or in a sub-window. So step 1: find out the sub-window number in which the indicator is drawn. Look in the direction ofOperations with charts.

Step 2: when there is a subwindow number, it is easy to draw a line. SeeOBJ_TREND help, and"TrendCreate" function parameters

//+------------------------------------------------------------------+ 
//| Создает линию тренда по заданным координатам                     | 
//+------------------------------------------------------------------+ 
bool TrendCreate(const long            chart_ID=0,        // ID графика 
                 const string          name="TrendLine",  // имя линии 
                 const int             sub_window=0,      // номер подокна 
                 datetime              time1=0,           // время первой точки 
                 double                price1=0,          // цена первой точки 
                 datetime              time2=0,           // время второй точки 
                 double                price2=0,          // цена второй точки 
                 const color           clr=clrRed,        // цвет линии 
                 const ENUM_LINE_STYLE style=STYLE_SOLID, // стиль линии 
                 const int             width=1,           // толщина линии 
                 const bool            back=false,        // на заднем плане 
                 const bool            selection=true,    // выделить для перемещений 
                 const bool            ray_left=false,    // продолжение линии влево 
                 const bool            ray_right=false,   // продолжение линии вправо 
                 const bool            hidden=true,       // скрыт в списке объектов 
                 const long            z_order=0)         // приоритет на нажатие мышью

Oh, I see they've finally added these new-old functions to the help too.

[Sile Si]

No doubt, the EA attached to si modifies vtbr. Places T/P positions on the quotes of its instrument "si".

If I attach an EA to vtbr, it does not modify si, it works only on its instrument

Any explanation for this?

There is no modification in the code except this one:

   if(TakeProfit>0)
     {
     if(!RefreshRates())
            return;
      int total=PositionsTotal();
      for(int i=total-1;i>=0;i--)
        {
         if(m_position.SelectByIndex(i)) // selects the position by index for further access to its properties
           {
            if(m_position.Symbol()==Symbol())
              {
               //if(m_position.PositionType()==POSITION_TYPE_BUY)
               if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_BUY)
                 {
                  if(m_symbol.NormalizePrice(Aver_Pr_sell_nett()+ExtTakeProfit)!=m_position.TakeProfit())
                    {
                     m_trade.PositionModify(m_position.Ticket(),
                                            m_position.StopLoss(),
                                            m_symbol.NormalizePrice(Aver_Pr_sell_nett()+ExtTakeProfit)
                                            );
                     Sleep(300);

                    }
                 }
               //==//
               //if(m_position.PositionType()==POSITION_TYPE_SELL)
               else if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_SELL)
                 {
                  if(m_symbol.NormalizePrice(Aver_Pr_sell_nett()-ExtTakeProfit)!=m_position.TakeProfit())
                    {
                       {
                        m_trade.PositionModify(m_position.Ticket(),
                                               m_position.StopLoss(),
                                               m_symbol.NormalizePrice(Aver_Pr_sell_nett()-ExtTakeProfit)
                                               );
                        Sleep(300);
                       }
                    }
                 }
              }
           }
        }
     }
