The article states that....

Under the mechanism which only became effective Monday, a move of 5 percent in the CSI 300 triggers a 15-minute halt for stocks, options and index futures, while a move of 7 percent ‘close the market for the rest of the day’.

So it appears this will be status quo under the mechanism they have effective now.

and if you wrote short options, you’re history.

These mechanisms cause selloffs because people want to sell before the market shuts down if there is the slightest hint of panic.
