How it works
When buy and sell order volumes become significantly skewed and cannot be balanced within the ordinary price range, the exchange displays a special indicative price (a special quote) in place of a regular market price. The special quote is updated step by step at set intervals, based on the state of supply and demand.
Relationship to the daily price limit
If repeated updates of the special quote cause the price to reach the upper or lower boundary of the daily trading range (the daily price limit), that state is commonly referred to as limit-up or limit-down. The special quote mechanism exists to help form a price by collecting orders when a sharp price movement occurs.
