7% decline
If the S&P 500 falls 7% from the previous session’s close before 3:25 p.m. Eastern, all stock-market trading halts for 15 minutes.
13% decline
After stocks reopen, it would then take a 13% decline by the S&P 500 before 3:25 p.m. to trigger a second trading halt, which would also last 15 minutes.
20% decline
After a second trading halt, it would take a decline of 20% to trigger a so-called Level 3 circuit breaker. Once a 20% drop occurs, trading is halted for the remainder of the day.
I think we will see this or very close to it - today EST 16th March 2020
