Frustrating Yep. But let's clarify the facts: * Nasdaq specifically refused to discuss intermarket linkage with the Amex when Amex notified them that it was entering the Nasdaq business. Ask the SEC. * Nasdaq, by rule, prohibited Amex from participating in SelectNet. * Nasdaq...

Look closer. The Amex specialists are not locking and crossing the markets. They are getting locked and crossed by ECNs and market makers who are just ignoring the Amex. When they are in a locked or crossed situation, they are there passively. If a trader cannot hit the Amex quote, it is...

a couple related points.... Interestingly, there is nothing inherent about a given stock that makes it a Nasdaq or NYSE listed stock. The listing venue is often a choice made by a CEO or CFO or a company, which is usually/often driven by the Investment Banker for the firm at the time the...

I also understand that the Amex plans to rollout more stocks this Thursday. They're supposed to be publishing the list later today. Also, apparently Brass is establishing linkage to the Amex for Nasdaq trading, so a lot more people should be coming into that market.

There is info on this on Island's website. This should have an interesting effect on SuperMontage. Over 30% of the NBBO in Nasdaq securities could be coming from Cinn. What's next? Will ISLD pull out of SuperMontage all together? :eek:

Jimbo, You make a good point regarding the QQQs trading on the ECNs. Quite electronic. The question is 'why'? From what I've read, in addition to technology, there are two additional reasons. One, QQQs like other ETFs have a different form of price discovery from equities. Price can be...

Don Bright has a point. Look at what is happening to the Nasdaq marketplace. Nasdaq trading desks are shrinking if not completely disappearing all over the street. Most market makers can't make any money in the decimal world. It takes about 50 executions to get any order of reasonable size...
