NO.PZ2015122802000027 问题如下 Currently, the market in a stois \"$54.62 bi offere$54.71\". A new sell limit orr is place$54.62. This limit orr is saito: A.take the market. B.make the market. C.make a new market. is correct.This orr is saito take the market. The new sell orr is $54.62, whiis the current best bi Therefore, the new sell orr will immeately tra with the current best bianis taking the market.考点Execution Instructions目前市场aler对某公司的报价为$54.62 bi offere$54.71。投资者希望以54.62的价格卖出股票。问下列哪个说法是最正确的。该报价可以成交。take the market就是以报出的指令价格成交。打比比方sell orr价格正好等于best bi立即成交了，这就是take the market。现在投资者报的卖价54.62正好等于aler的最高买价54.62，因此该订单可以马上成交。B.该报价可以看作是一次做市。make the market指如若买价报在best bi卖价报在 best ask,就是一次做市。本题的best bi best ask分别为54.62和5.71，而新的卖价是54.62没有落在best ask，所以这不叫make the market。C.该报价可以看作是做了一个新市。make a new market, 它是指报价报在最高的bi最低ask之间就叫做make a new market。根据aler的买卖报价，make a new market的范围是（54.62-5.71）也就是best bibest ask，所以不是make a new market. 为什么不选b呢
