苯乙烯期货开盘价遵循什么原则

Group 1 - The opening price of styrene futures is determined through a call auction method, following the principles of "price priority" and "time priority" [1] - Price priority means that buy orders at higher prices and sell orders at lower prices take precedence over other price orders [1] - Time priority indicates that when orders have the same price, the orders submitted first are prioritized over those submitted later [1] Group 2 - The opening price determination process involves a call auction period set by the exchange before each trading day, typically a few minutes before the market opens [2] - This call auction period consists of two phases: the input phase for submitting buy and sell orders, and the matching phase where orders are matched to determine the opening price [2] - During the input phase, traders submit their buy and sell orders with specified prices and quantities based on their predictions and trading strategies [2]
