BASE PRICE AND DAILY PRICE CHANGE LIMITS
Daily price change limits for future contracts is defined in the contract specifications by the Exchange. In the event that the upper or lower limit is calculated that it does not coincide with the price tick, the upper limit will be rounded to the upper price tick; and the lower limit, to the lower price tick.
For option contracts, on the other hand, no price change limit will be applied for premium prices. (For further information please refer to the Derivatives Market Procedure)
