Hello,

This is my first time using graphical objects in an indicator. I would need to draw a vertical line everyday at the same time "22:00", could you please guide me to a solution?

Thanks

Use Cycles instead of VLine.

Hello guys,

I could solve the issue with other code (really I could not apply the solutions given above), but not at all.

Now I get vertical lines for all the previous 22:00 candles, but I need the line in the coming 22:00 candle at the right side of the price (future), how could I get that?

This is the code:

...

for (shift=NumBars;shift>=0;shift--)

{
if (TimeHour(Time[shift])== Offset && TimeMinute(Time[shift])==0)
{
if(ObjectFind("Offset"+shift) != 0)
{
ObjectCreate("Offset"+shift, OBJ_VLINE, 0, Time[shift], 0);
ObjectSet("Offset"+shift, OBJPROP_STYLE, STYLE_DASHDOTDOT);
ObjectSet("Offset"+shift, OBJPROP_COLOR, White);
}
}

}

Help!

Thanks :)

Please use this to post code . . . it makes it easier to read.

  1. Next time be more precise with your original question.
  2. datetime now = Time[0],
             bod = now - now % 86400,  // Beginning of the day
             Hr22= bod + 22 * 3600;    // 2200
    VLine("2200", Hr22, Red);

Is it possible to draw vertical lines in the right side of the chart away from the current price by knowing only the date

For example assume current time is 2019.05.17 00:00  , and I want to draw a vertical line in the future at 2019.06.04 16:00 using the date information only ?

Yes.

Use ObjectCreate( and OBJ_VLINE

Or use this function for example:

//+------------------------------------------------------------------+ 
//| Create the vertical line                                         | 
//+------------------------------------------------------------------+ 
bool VLineCreate(const long            chart_ID=0,        // chart's ID 
                 const string          name="VLine",      // line name 
                 const int             sub_window=0,      // subwindow index 
                 datetime              time=0,            // line time 
                 const color           clr=clrRed,        // line color 
                 const ENUM_LINE_STYLE style=STYLE_SOLID, // line style 
                 const int             width=1,           // line width 
                 const bool            back=false,        // in the background 
                 const bool            selection=true,    // highlight to move 
                 const bool            ray=true,          // line's continuation down 
                 const bool            hidden=true,       // hidden in the object list 
                 const long            z_order=0)         // priority for mouse click 
  { 
//--- if the line time is not set, draw it via the last bar 
   if(!time) 
      time=TimeCurrent(); 
//--- reset the error value 
   ResetLastError(); 
//--- create a vertical line 
   if(!ObjectCreate(chart_ID,name,OBJ_VLINE,sub_window,time,0)) 
     { 
      Print(__FUNCTION__, 
            ": failed to create a vertical line! Error code = ",GetLastError()); 
      return(false); 
     } 
//--- set line color 
   ObjectSetInteger(chart_ID,name,OBJPROP_COLOR,clr); 
//--- set line display style 
   ObjectSetInteger(chart_ID,name,OBJPROP_STYLE,style); 
//--- set line width 
   ObjectSetInteger(chart_ID,name,OBJPROP_WIDTH,width); 
//--- display in the foreground (false) or background (true) 
   ObjectSetInteger(chart_ID,name,OBJPROP_BACK,back); 
//--- enable (true) or disable (false) the mode of moving the line by mouse 
//--- when creating a graphical object using ObjectCreate function, the object cannot be 
//--- highlighted and moved by default. Inside this method, selection parameter 
//--- is true by default making it possible to highlight and move the object 
   ObjectSetInteger(chart_ID,name,OBJPROP_SELECTABLE,selection); 
   ObjectSetInteger(chart_ID,name,OBJPROP_SELECTED,selection); 
//--- enable (true) or disable (false) the mode of displaying the line in the chart subwindows 
   ObjectSetInteger(chart_ID,name,OBJPROP_RAY,ray); 
//--- hide (true) or display (false) graphical object name in the object list 
   ObjectSetInteger(chart_ID,name,OBJPROP_HIDDEN,hidden); 
//--- set the priority for receiving the event of a mouse click in the chart 
   ObjectSetInteger(chart_ID,name,OBJPROP_ZORDER,z_order); 
//--- successful execution 
   return(true); 
  }

Or use this function for example:

Thanks Marco , it did not work , I'll post the entire code , you will see in the alert that I have the right date but I am unable to create the line on that date 

What I am trying to achieve is save the information I have on the chart in case its lost as sometimes when the market is closed and MT4 opens on the VPS with no connection to the broker the information is lost
So before the weekend I want to keep my lines which are in the future section of the chart ( on the far right ) to do so I created a symbol on the chart , saved the date for that Symbol then use that date to recreate the lines .. all is good except the part to re-create the lines and I wonder if someone could help with that

Use D' format to set the wanted time in ObjectCreate() 

ObjectCreate(0,"v_line",OBJ_VLINE,0,D'2019.06.04 16:00',0);
