For example,

2024 SPY drops over 3 weeks (actually just 3 days) and rebounds in 3 weeks.

2018 Oct-Dec SPY drops 12 weeks and rebounds over 7-8 weeks….

The current drop will be Sep-Nov or 8 weeks…so a minimum of 5 week rebound.

Same with TLT….it has had 6 month downtrend and will have an 8-9 week uptrend.

AND on a longer rebound…there’s more gravy near the end of the rebound.
