They're not literal circuit breakers. "Circuit breaker" is the name for exchanges rules that stop trading when the price does something crazy.
Ok that makes sense thanks
Japanese markets limit the maximum amount stock can move in single day. These limits are known as circuit breaks, basically when you get over current that is too much drop it shuts off.
Not sure if there is same for other direction too.
I assume “circuit breakers” is a technical term for some automatic system that is built in to the market to activate if some condition occurs, to alter market behavior.
Circuit breakers are the term for exchanges shutting down trading if there’s unusual activity like too much of a price swing in one day.
High amount of trades doesn’t, but the drops are what’s triggering the breakers.
