To be specific there is no exchange or benchmark price for forex. When you trade forex you are directly dealing with the provider of the other side of the price vs a matching engine provided by a disinterested third party.

There are multi-dealer platforms that abstract this but you are still directly covered by your contract with the partner counterparty.

Most direct api integrations and multi-dealer platforms implement circuit breakers but they aren’t regulated like equities or futures exchanges.

Compare that to the link which is a forex futures exchange which is subject to cftc regulations around circuit breakers.
