The drop on the $QQQ looks a lot more severe than the bounce here for the $SQQQ and it is a clear bounce and clear sign of a reversal but not retest yet.
On the $QQQ the drop has been so strong that it looks like a retest of the 50 Day MA from below may not come but the Mega Caps start reporting from next week so they will have the influence to bounce the market back to retest.
I do not believe the 50 Day MA will be recaptured again for support and Wave A continues down for the $QQQ.
Likewise, when the $SQQQ retests its 50 Day MA and holds, then you have your signal to buy.
