Exchanges
Exchanges have purchased many of the independent ECNs (electronic communications networks, the basis for electronic trading), expanding their presence in the budding electronic trading market. For example, NYSE Euronext bought the Archipelago ECN, and Nasdaq bought Instinet, its own ECN. CME and CBOT offer Globex and e-cbot, respectively, etc. ICE and ISE are almost exclusively electronic.
