I believe it's true for the other direction as well, it's just pretty rare to see a 7% upward move in a single day. I mean, it's rare to see it on the downside too, but not as rare.

Limit up/down rules are not discretionary. They're circuit breakers that fire deterministicly.

It's important to note that limit up/limit down (LULD) is not the same thing as the circuit breakers. They have a very specific meaning and operate independently (with much more complicated rules as well). You probably know this, but others reading your comment will probably not!

There is also no automatic upside circuit breaker.
