After quickly dropping down to support in the early morning, massive and sustained buy programs, likely from the Fed pushed NQ up all day to new high, with some profit-taking decline into the close.
With a strong positive momentum going into the close the expectation is for a gap-up open in the morning. If so, look for a high-probability gap-close trade at the opening bell. If the uptrend is to continue right away, gap-close should serve as support for the next leg up.
Breaking below the gap-close however implies NQ is going down to the next support at 3130 before bouncing.
A gap-down open would nengate the above analysis, then key resistance and line-in-the-sand would be at gap-close
