Hypothesis: Structurally we could be bullish even if we touch the 9.5k one of this years last months. So yes, the CME Gap (whether it exists or not) can be filled without big structural problems.
Also matches fib retracement:
From a weekly perspective this is also possible; As long as we stay above the 21EMA we're in bulls territory. Even if we wick through it all the way to 9.5-10k area.
