所有跟帖： 

• 这些数据与我前面贴出的图示是吻合的。如果需要看一年的数据，我也可以去搬过来。 -老看客- ♂ (0 bytes) () 12/28/2018 postreply 17:13:46

• 如果看了这些数据，你还要“理直气壮”地说这些天的交易量只有平时的一半，我向你发誓：我绝不再回应，你赢了！ -老看客- ♂ (0 bytes) () 12/28/2018 postreply 17:18:09

• 这里面的交易量也是Dow Jones 30个指数股的交易量。要想有代表性，至少也要拿SP500的交易量出来吧？ -Chinucks- ♂ (0 bytes) () 12/28/2018 postreply 19:15:37

• 要是连指数股交易量和整个股市交易量的区别都搞不清楚，真没必要讨论了。 -Chinucks- ♂ (0 bytes) () 12/28/2018 postreply 19:26:31

• Dow 指数也罢，标普也罢，它们显示的交易量趋势是基本一致的。 -老看客- ♂ (0 bytes) () 12/28/2018 postreply 20:19:38
