$QQQ update: the "bullish mode" on close was an illusion... after a super tight "double top" ~ 340.8 ~> impulsive DOWN, al the way to a 1st Support Zone around 337. This level might hold ... for a while. No index positions right now, but watching $QQQ & $SPX like a hawk. Reduced my "long exposure" to ~7%. I agree with Tom Lee: "Time for bulls to get worried!"
