How to draw breakout boxes through 00:00?

Hi guys,

I'm just a beginner learning how to write indicators and EA,

Now I'm trying to make my own by changing some scripts and parameter of the panca-eagle breakout indicator,

but I'm now stuck since I don't know how to make the rectanglar boxes drawn through 00:00,

I would like to set the time for the boxes to be drawn from 1500 to 0430 of the next day,

but this can't be done by solely changing the external variables since the rectangles draw backward to 0430 of the same day,

I guess some changes should be made in the part "Custom indicator iteration function", am i right?

anyway, I've tried making some changes to that part but it still didn't work right, could anyone help?

Thanks for all your help!!!

I'm posting the script below. Since this script has already been shared in this website, i guess the author won't mind.
