Unfilled QQQ Gaps and Grim SPX Signal Warn Contrarians

And so we go into the weekend with two unfilled gaps in $QQQ and a rather ominous-looking $SPX chart. I suspect that absent a dramatic tweet sentiment might be pretty gloomy over the weekend... and that contrarians might take notice. https://t.co/voHUQKVB2z

67% Downside Day Insignificant; QQQ Gap Remains Unfilled

Market’s Response to Oversold Beats Oversold Label, Gap Filled

The important thing isn't that the market's oversold -- it's how the market responds to its oversold condition. Meanwhile, Thursday's gap was finally filled. https://t.co/vTVOt0gTEs

SPX Gaps Lower, Bullish Rally Needed to Halt Decline

$SPX closed below the Dec low and today's gap, unlike others recently, wasn't closed during the day. This isn't fatal yet (the Jan 20 one [dashed line] wasn't closed until the following day) but the bullish forces need to pull...
