Infinite loop (endless loop) for owl-carousel on the front page

I have bought the forest theme.
I would like to set up the owl-carousel for the front page properties with the large images to loop endlessly. How to do that?
Aslo if possible it would be good if the properties could be displayed randomly so the website is not borred in the way that every time you come to the website the same property is displayed first.
Thank you.
