Redraw objects after 24hrs

[J Webster]

I have an indicator that draws a box around the working hours candles of a chart.

It needs to reset itself every hour between the hours of 1900 and 0600. How could I do this with some code?

Do I have to simply run the delete objects code every hour and the start function will simply redraw everything?
