calls its proposed SuperMontage computer trading system a fairer, faster, cheaper and better way to trade Nasdaq securities. Its rivals, the electronic communications networks (ECN), have another name for it:


ECNs are computerized trading systems that anonymously match buyers and sellers of stocks. And they have been stealing traffic, including orders from some major Wall Street brokerages.

In what has become a major battle in the industry, the ECNs and others complain that SuperMontage would allow Nasdaq's parent, the

National Association of Securities Dealers

, to create an inefficient, anticompetitive system in which orders would be forced to funnel through Nasdaq.

demanding detailed information about SuperMontage.

Privately, Nasdaq executives dismiss the ECN criticism for the same reason the ECNs blast SuperMontage: self-interest.
