&quot;Both circuit breakers&quot; refers to the 7% all-day halt circuit breaker and the 5% 30-minute halt circuit breaker introduced in the previous paragraph (which I omitted for brevity). A full quote would make more sense:<p>&gt;The proposed mechanism will be tied to the benchmark CSI300 Index, which tracks the largest listed companies in Shanghai and Shenzhen, where a move of 5 percent in either direction from the index&#x27;s previous close will trigger a 30-minute trade suspension across the country&#x27;s equity indexes if the move occurs before 2.30 pm local time. After that, a 5 percent move will freeze trading until the market close at 3.00 pm.<p>&gt;Meanwhile, a 7 percent rise or fall in the CSI300 Index will prompt a trading halt in the Shanghai and Shenzhen stock exchanges for the rest of the day, the statement posted on the exchange&#x27;s website said. Both circuit breakers will only be activated once a day.
