If you want to see how price should react after a fakout.
For example: BTC
$84k fakeout
$SOXL is the most recent and perfect example.
Price broke below the low with volume
Sellers jumped in
Shorts piled in
Price reclaimed the low and squeezed the bears with a 15% move up.
When price breaks a major low and reclaims it, it traps the traders and you expect the price to squeeze them with a counter really.
The faster, The better
