Due to Market Volatility, we want you to know these levels. They are updated on this CME page daily.
A price limit is the maximum price range permitted for a futures contract in each trading session. When markets hit the price limit, different actions occur depending on the product being traded. Markets may temporarily halt until price limits can be expanded, remain in a limit condition or stop trading for the day, based on regulatory rules.
Effective October 12, 2020: Overnight limits will expand from +/- 5% price limit to +/- 7% limit plus 3.5% dynamic circuit breaker.
What are Dynamic Circuit Breakers?
Dynamic Circuit Breakers monitor for significant price movements during a trading session. DCBs define an upper and lower limit of how far an instrument is allowed to move in a configured time interval (within 1-hour).
What happens if a 3.5% Dynamic Circuit Breaker is triggered?
If a contract market moves beyond +/- 3.5% within an hour, trading will be paused for two minutes.
