A price limit of 4% (minimum limit) above or below the preceding 

day’s settlement price. The Exchange may, in its sole discretion, 

adjust the price limit for such futures contract in response to 

market risk conditions. In general, international markets 

do not prescribe a price limit but most have established circuit 

breakers.

The ICE Brent adopts interval price limits functionality serving as 

circuit breaker to reduce short-term price fluctuations. Although 

it is eective on every trading day, it can be only triggered in a 

very short time under extreme price uctuations. The WTI crude 

futures introduces Dynamic Price Limit Functionality: i.e. the upper

and lower price fluctuation limit will be calculated by utilizing 

the dynamic variant in continuously rolling 60-minute look-back 

period. When the price exceeds the dynamic price fluctuation 

limits, then a two minutes trading halt will commence. After the 

fourth triggering event on a trading day, there shall be no further 

special price fluctuation limits.
