On Monday NQ opened with a gap-up, to complete its wave 5 rally from the July 14th swing low. It was a typical wave 5 gap, a gap-reversal.
NQ high of the day was just shy of its 12,200 resistance. Profit-taking and new selling caused NQ to drop down to 11,850 support zone.
11,850 will be support for tomorrow with first resistance at 12,000. Failure to stay above 11,850 is likely to trigger more selling with potential support at 11,700 then 11,500.
