Following QQQ trading ranges when experiencing dips. Illustrating a proper gap-fill with today's sell off and key support test with bull volume buy off Oct week 1 resistance @ 282.85 which is proving to be today's support. Higher volume in final minutes if trading (HFT likely) off oct wk 1 resistance. Potential risk is cease of stimulus discussion. Hoping to hear more of the same from that perspective and exit after an expected gap up tomorrow.
