what does circuit breaker mean?

potsy52 : Trying to slow things down

I Love Edgy Waifus : Circuit Breaker is when the system is getting too many orders at once, so it shuts off for a bit to stop overloading basically. But some people also think they're used in shady manners for manipulation depending on the stock. :o

MooMamaLlama I Love Edgy Waifus : it is a legitimate thing, but it does often seem shady when it gets a halt right before it hits your own TP lol
and because it's really only needed when super high volume hits at once, that super high volume has a lot of voices to complain it's being manipulated...
