available trading time of Gold is 22:00 ~ the next day 21:15(UTC) ,
so, Gold is stopped for 45 minutes (21:15 ~ 22:00 ).

you can see the note of our site or http://www.cmegroup.com/market-data/delayed-quotes/metals.html

of course, http://www.cmegroup.com/market-data/delayed-quotes/metals.html is delay.
but if  times go , you will  know it.

I think you may see the gold  during that time.
we have checked our system. and then our system had no problem.
