Note the first parameter of the function

string  ObjectName( 
   long  chart_id,           // идентификатор графика 
   int   pos,                // номер в списке объектов 
   int   sub_window=-1,      // номер окна 
   int   type=-1             // тип объекта 
   );

It is present in all functions of work with graphic objects.

Using the correct identifier you can easily get the object properties from any chart.

[Vladimir Karputov]

Aleksandr Egorov:
the long is the m5 and tg 0 current chart, but the string sumbol how? i need it on the pound from the chart of the euro or something i do not understand

No, no timeframes - you need a chart ID:ChartID

One of the options: run a script on the chart with the line, which printsChartID, then you can access the line property from another chart. For example, if it is a horizontal line, then throughObjectGetDouble

thanks

[Vladimir Karputov]

Aleksandr Egorov:

thanks

There is another option: you just need to know the name of the graphical object and the type (you need the name to search through all graphs, and the type to find exactly the right object) ...

[Vladimir Karputov]

Aleksandr Egorov:

thanks

Variant #2: set name, type of object and in which window to search for it ("0" - in the main window). The search is performed in OnInit and if the object is found, we save the chart identifier to the m_obj_chart_id variable.

[Konstantin Kulikov]

If I place market orders(TRADE_ACTION_DEAL) with specified Stop Loss and Take Profit levels, but the broker has a ban on setting orders with SL or TP, will the order be cancelled or set with zero SL and TP?

[Aleksandr Egorov]

Vladimir Karputov:

Variant #2: specify name, object type and in which window to search for it ("0" - in the main window). The search is performed in OnInit and if the object is found, we save the chart identifier to the m_obj_chart_id variable.

Thank you even more

And your mistake is in the start price formation:

//--- start work
   double start_price_ask=m_symbol.Ask()-ExtUpGap;
   double start_price_bid=m_symbol.Bid()+ExtDownGap;

I recommend to make the starting price separately for Stop and separately for Limit pending orders.

Hello Vladimir!

Please help me modify the start price of the script below:

//--- start work


   double start_price_ask=0.0;
   double start_price_bid=0.0;
   if(InpPending==stop)
     {
      start_price_ask=m_symbol.Ask()+ExtUpGap;
      start_price_bid=m_symbol.Bid()-ExtDownGap;
     }
   else
      if(InpPending==limit)
        {
         start_price_ask=m_symbol.Ask()-ExtUpGap;
         start_price_bid=m_symbol.Bid()+ExtDownGap;
        }

The script should place pending orders not based on Ask and Bid, but on the hight and low of the previous bar (candlestick).

Sincerely, Vladimir.
