CME's BTC is around 84000, so there is basically no gap left. A small trick for the recent weekend market is to make up for the gap by doing reverse selling. If you pull too much over the weekend, you can start short selling around Sunday evening; On the contrary, go long. The premise is that the gap must be large enough, and this kind of difference of a few hundred dollars is meaningless. The estimated hit rate is 8/10.
