Shown here is the same fib series in three different timeframes.
Left chart shows its "Genesis" (birth) and the growth rings since.
Right side charts show the same fibs but in smaller timeframes.

The rebound WILL happen at "a" fib, the question is "which" fib?
So we have "exact" levels of interest for entries, stop losses, tp's.
Then we know very quickly if we are wrong or if spectacularly right.

The retrace wave has just now reached a crucial support fib at 2,665.23
This is a "semi-major" ratio (dark blue) with minors just above and below.
The "Majors" are Golden fibs (1.618 multiples) last one was the 3,037 top.

I do not use "Fibs" in the "traditional" manner (retracements).
I use Fibs to plot "Ripples" (extensions) created by "Impulses".
Then look for "Confluences" to map the "interference Pattern".
