What time does the daily bar close on ES?

I understand the trading hours but I'm wondering if anyone knows whether a daily bar closes at 3:15pm CST or at 5pm CST?

 

The ES trading day goes from 16:30 EST to 16:15 EST the following day. Sunday starts at 18:00 EST.

 

Thanks Jebb

 

do you guys trade pre-market? I rarely do, but with all the volatility it's pretty nice.

PS. I'm always flat by 3:55. Post market can get ugly!
