Start Time - End Time

New comment

Hi there, does anyone know how I would add a specific start time and end time to this indicator so that it doesn't cover the whole day?

You learn to code it or pay (Freelance) someone to code it.

time[i]/3600-floor(time[i]/86400)*24 should give you the hour of the i bar. If all buffers are equaled to zero for some i it shouldn't draw a bar on it.
@kypa, thank you for your helpful reply, I'll give it a try!
