Nasdaq- No Christmas rally this year?

After reaching a new all-time high at 16700, Nasdaq fell 1000 points pretty quickly, just to find support in the old ATH's zone.
From here, bulls took control and elevated the price again.
At this moment Nas100 is trading in a strong resistance zone and a new leg down could follow from here.
On the other hand, a break above this resistance could mean further gains for the index and, indeed, a nice Christmas for bulls with a new ATH
