HF certainly know how to manipulate markets, no doubts, however, SQQQ is different from most ETF and stocks in it's not SQQQ volume that moves it, Rather it's the underlining 100 index and futures! Futures determine premarket open ... If you look at charts SQQQ matches futures in movement. I also watch big tech as has big impacts to QQQ and inturn SQQQ. That said, looking to be fantastic (so far) for SQQQ again tomorrow!
