问题如下：
Consider an order-driven system that allows hidden orders. The following four sell orders on a particular stock are currently in the system’s limit order book. Based on the commonly used order precedence hierarchy, which of these orders will have precedence over others?
选项：
A.Order I (time of arrival of 9:52:01).
B.Order II (time of arrival of 9:52:08).
C.Order III (time of arrival of 9:53:04).
解释：
C is correct.
Order III (time of arrival of 9:53:04) has precedence. In the order precedence hierarchy, the first rule is price priority. Based on this rule, sell orders II, III, and IV get precedence over order I. The next rule is display precedence at a given price. Because order II is a hidden order, orders III and IV get precedence. Finally, order III gets precedence over order IV based on time priority at same price and same display status.
