IB不支持客户配售打新股，但支持IPO当日成交前的竞价撮合交易（指上市开始成交前的一两个小时时间内挂单），所以在IPO当日，在看到报价成交波动之前的竞价时段即可挂单排队；而如果等看到报价波动成交出现后的那几分钟再开始挂单，大量买卖盘瞬间涌入交易所系统，此时的线路的繁忙及堵塞会延迟您的委托指令单的进场以及回报确认（造成经纪公司的系统普遍不能及时确定指令是否已成交、也无法响应撤单的指令）。阿里巴巴上市当日在成交开始前，IB客户如挂限价LMT单$93超过$92.7等，都可以其撮合开盘价$92.7的开盘价在开盘的瞬间完成成交执行。

SEC上面有一个针对入门者的资料： Trade Execution: What Every Investor Should Know 网页链接
楼主最好看一下，没有及时成交，这种是不受SEC保护的；没有撤单成功之前，最好不要去下新的委托，以免重复。
Trade Execution Isn’t Instantaneous
Many investors who trade through online brokerage accounts assume they have a direct connection to the securities markets. But they don't. When you push that enter key, your order is sent over the Internet to your broker—who in turn decides which market to send it to for execution. A similar process occurs when you call your broker to place a trade.
While trade execution is usually seamless and quick, it does take time. And prices can change quickly, especially in fast-moving markets. Because price quotes are only for a specific number of shares, investors may not always receive the price they saw on their screen or the price their broker quoted over the phone. By the time your order reaches the market, the price of the stock could be slightly – or very – different.
No SEC regulations require a trade to be executed within a set period of time. But if firms advertise their speed of execution, they must not exaggerate or fail to tell investors about the possibility of significant delays.
Your Broker Has Options for Executing Your Trade
Just as you have a choice of brokers, your broker generally has a choice of markets to execute your trade
