Make sure your symbols are set for the June contract month specifically today. If you use "continuous" chart settings, it will blend the March & June together. That throws off price action going backward thru the transition due to premium spread between contracts.
That is true for short-term tick charts, volume charts and time charts alike. Four sessions per calendar year have the charts slightly amok. This is one of them.
As for the overnight gap, it is a futures rally back above yesterday highs. Might as well get used to seeing such overnight moves... large gaps are common during normal to high volatility. Gone for now (maybe for good) are the ultra-low VIX market conditions.
