NASDAQ:SQQQ   ProShares UltraPro Short QQQ
I don't have the pro version to show side by side, but the 2018 correction (on a 2HR timeline) scales remarkably similar to the current correction (on a daily timeline).
Both 2018 and current show a triple bottom formed before making the HUGE upswing to close out the correction.
Even the dates of these price actions proportionally correspond between the two corrections.
I suspect SQQQ will breakout in the next two months.

Good luck.
