问题如下：
Zhenhu Li has submitted an immediate-or-cancel buy order for 500 shares of a company at a limit price of CNY 74.25. There are two sell limit orders standing in that stock’s order book at that time. One is for 300 shares at a limit price of CNY 74.30 and the other is for 400 shares at a limit price of CNY 74.35. How many shares in Li’s order would get cancelled?
选项：
A. None (the order would remain open but unfilled).
B. 200 (300 shares would get filled).
C. 500 (there would be no fill).
解释：
C is correct.
The order for 500 shares would get cancelled; there would be no fill. Li is willing to buy at CNY 74.25 or less but the minimum offer price in the book is CNY 74.30; therefore, no part of the order would be filled. Because Li’s order is immediate-or cancel, it would be cancelled.
请问 1.如果如果价格达到了 数量不够的话是会部分成交么？ 2.价格低于74.25 也会成交么？ 谢谢
