I think this is still in effect today, but not points % , I dont think we are even close.Didn’t there used to be some safeguard to prevent these runs? I thought there was an automatic freeze in trading put in place years ago if it dropped like 500?
What are market circuit breakers? 7:56 PM ET Fri, 8 Jan 2016 | 01:02
Stock exchanges attempt to ease panic selling by taking certain steps to halt trading. These moves are called market circuit breakers—or collars. Under extreme conditions that could trigger market disruptions, exchanges can invoke Rule 48 to make it easier and faster to open stocks.
When do market circuit breakers kick in?

Under the revised rules approved by the SEC in 2012, market-wide circuit breakers kick in when the S&P 500 Index drops 7 percent (Level 1), 13 percent (Level 2), and 20 percent (Level 3) from the prior day's close.
A market decline that triggers a Level 1 or Level 2 circuit breaker before 3:25 p.m. will halt market-wide trading for 15 minutes, while a similar market decline "at or after" 3:25 p.m. will not halt market-wide trading.
