UX - my subjective opinion
Resolution - frequency of trades for the last 24 hours
So as you can see only two exchanges have a decent trading volume and resolution. It's still not enough for day trading, but ok for building long-term positions. As a day trader I'd like to see such volume on each pair (more than $20M) and a slightly higher resolution of about 1-5 second.
I hope by the end of 2018 we will reach these levels.
