枫下家园 / 理财投资税务 / 请问fox69等各位用过Ameritrade的大侠,实时的streamer中的volume是金额还是股数?bid和ask价格前有时会出现island的标志,这是什么意思?多谢!

股数,do not use island, use the nasdaq.
if you did not pay the fee for level2 or you do not have elite servie,
you may not see the level2 real data.

多谢,多谢,这么快。我刚刚在Ameritrade开户,资金还没有从TD转到Ameritrade。是普通的帐户。只是还是没有明白island,nasdaq之间的关系。同时level2的数据和我现在看到的streamer有什么不同呢?

可以看到很多买家和卖家的bid price and bid volume with nasdaq level2.
or you can only see only one bid price. In fact, it's no much use of level2

1. should be number of shares instead of value of shares.2. I'm not quite sure what "Island" means, but I assume it is one of the Institutions. When you look at Yahoo finance, you can find only two institutions: Island and Archipelago .
