问一道题:NO.PZ2018062002000089

问题如下:

If the time lag between when an order to trade a security is placed and when the order is executed increases, how does the market efficiency changes correspondingly?

选项:

A.

Market efficiency decreases.

B.

Market efficiency stays the same.

C.

Market efficiency increases.

解释:

A is correct.

If the time lag between when an order to trade a security is placed and when the order is executed increases, it is an indication that operating inefficiencies increases and it reduces market efficiency.

这个题干怎么翻译,读不太懂。这个是交易延迟了,卡单了?还是一段时间内,被执行的订单数量增加了?

这里说的是如果交易从下单到真正被执行中时间的延迟增加,说明市场有效性下降。
