On Wednesday NQ closed at the high of the day just below 21,800 resistance zone. NQ is likely to continue to rally in the morning with resistance at 21,900 - 22,100.
To do so it must break above 21,800 then 21,900. Failure to break above could attract short-sellers.
First strong support is 20,550 and it should not be broken on Thursday without any major unexpected market-moving news..
Selling may have to wait until next week Monday as long as 20,550 holds.
