问题 多项选择题

集合竞价确定成交价的原则是()。

A.产生最大成交量

B.与选取价格相同的委托一方全部成交

C.高于选取价格的所有卖方有效委托和低于选取价格的所有买方有效委托全部成交

D.高于选取价格的所有买方有效委托和低于选取价格的所有卖方有效委托全部成交

答案

参考答案:A, B, D

解析:

 根据我国证券交易所的相关规定,集合竞价确定成交价的原则为:①可实现最大成交量的价格;②高于该价格的买入申报与低于该价格的卖出申报全部成交的价格;③与该价格相同的买方或卖方至少有一方全部成交的价格。如果有两个以上申报价格符合条件,深圳证券交易所取距前收盘价最近的价位为成交价;上海证券交易所则规定使未成交量最小的申报价格为成交价格,若仍有两个以上使未成交量最小的申报价格符合要求,中间价为成交价格。

I remember returning to Seattle after being小题13:in the US Army for about two years. I had just been promoted to Captain at that time. And full of pride,I walked into my parents’ restaurant,but the小题14:thing Dad said was,“How about your小题15:up tonight?” I couldn’t小题16:my ears! I am an officer in the Army! But it didn’t 小题17:as far as Dad was concerned,I was just 小题18:member of the team. I reached for the mop. Working for Dad has taught me the devotion to a小题19:is above all.
