it's will trigger circuit breakers soon.
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.
CME Group U.S. equity index price limits (and corresponding CME and CBOT rules) are designed to coordinate with circuit breakers provisions as applied by the New York Stock Exchange (NYSE).
7%, 13%, and 20% price limits are applied to the futures fixing price and are effective from 8:30 a.m. CT – 3:00 p.m. CT. Mondays through Fridays.
5% up-and-down limits are effective 5:00 p.m. - 8:30 a.m. CT. Sundays through Fridays; and 3:00 p.m. - 4:00 p.m. CT, Mondays through Fridays. Between 3:00 p.m. - 4:00 p.m. the 5% price limit will not be allowed to breech the 20% daily limit.
