NQ stayed above key support of 7840 but did not attract any buyers to caused a rally. NQ simply traded sideways in a very narrow trading range, setting up another down-leg if 7840 support breaks.

 

For Tuesday 7840 remains key support price level, a break could trigger some fast short term algo sell programs, if so, supports are 7800 then 7720

 

If NQ could stay above 7840 we could see another sideways day like Monday's or a rally day. But the patterns is indicating a potential drop to 7800 support before a rally attempt.
