Depends on which bounce. Do you mean the first minor bounce or THE final downside on QQQ before it reverses after the next correction? So far we had a backfill of today’s gap which was a natural & likely pivot point.
Assuming the market takes out the bottom of that gap with conviction soon (Friday’s close), the next support where a bounce is likely is around 168.90. My preferred pullback target at this time is 168.85 where I would expect a decent bounce & quite possibly, the end to any correction that might set in over the next week or so.
