Cant connect to Collective2

Hello fellows . Im new to collective and trying to connect my system with no luck. Can you tell me if *QCLK5 or *CLK5 or … would be correct symbol for may crude contract.
Thanks in advance

Hello Vitali, click on this link to see symbols. I am showing a couple different contracts available, maybe the one you are trading has low volume, so is not available. Globex I believe closes for an hour each day.
