Can anyone show me how to place a VLine at the start of the day, for a specific time.  I am on EST and would like to show, on my chart, the start of the day.  Which is midnight.  My chart time is 5 hours ahead of EST.

        ObjectSet("DayStart", OBJPROP_COLOR, Orange); 

Above is the code I generally use, for VLine.  I can change the value of Time[0] to a different bar number, but was hoping that there was a way to set VLine by time.

Control Y does that for H1 and smaller charts.

Yes, but I want to show day beginning at midnight, EST, not 5:00 p.m.  EST.
