Use this.

actually I'm new to mql4 and i couldn't do anything with your code :)

Thank you very much

I would like to create two Lines showing the "opening bar" for daily time frame in the lower time frame

The problem with the following code I'm not able to change "color, width, ...) also I don't know if it update auto or not.

    ObjectCreate(0,PERIOD_D1,OBJ_VLINE, 0,Time[1],0 );

Perhaps you should read the manual. 1440 is not a valid string for the name.
If you want it to be on the daily open why are you putting it on newest completed bar of the current timeframe instead of the start of current day?
It will not auto update. Once created you have to move it. We just discussed this Object is not automatically refreshing (Mimi) - MQL4 forum
Why don't you use the built in one? options -> chart -> show period separators (control-Y)

Hi WHRoeder,

Thank you for reply and suggestion. I know about built in option, but i don't like too many separator lines to show in the chart. any way I think i finally get one step ahead with the help of some code from Mr. GumRai.
But I couldn't add it for the current bar [bar 0].

Any advice will be highly appreciated.

  int Higher_Timeframe=PERIOD_D1;
  datetime higher_time=iTime(Symbol(),Higher_Timeframe,0);
  int shift=iBarShift(Symbol(),0,higher_time);

    string obj_name = "testobj";
    int    chart_id = 0;
    
    ObjectCreate(chart_id,obj_name,OBJ_VLINE,0,Time[shift+1],0);
    
    ObjectSetInteger(chart_id,obj_name,OBJPROP_COLOR,clrYellow);
    ObjectSetInteger(chart_id,obj_name,OBJPROP_STYLE,STYLE_SOLID);
    ObjectSetInteger(chart_id,obj_name,OBJPROP_WIDTH,1);
    ObjectSetInteger(chart_id,obj_name,OBJPROP_BACK,false);
    ObjectSetInteger(chart_id,obj_name,OBJPROP_SELECTABLE,true);
    ObjectSetInteger(chart_id,obj_name,OBJPROP_SELECTED,false);
    ObjectSetInteger(chart_id,obj_name,OBJPROP_HIDDEN,true);
    ObjectSetInteger(chart_id,obj_name,OBJPROP_ZORDER,0);

Thanks
