Instinet, the electronic communications network (ECN), plans to display orders on Supermontage, Nasdaq's stock trading system, in a move that could secure the future success of Supermontage.

Instinet will begin displaying orders in January following the consolidation of Instinet with Island, a competing ECN that Instinet bought last year. The new ECN, which will be called Inet, will be the largest such network in the US with almost double the order flow of Supermontage.
