Denver, CO – October 12, 2006 – Selero, Inc. announced today that its new Trade Execution System (STX) is now fully supported by the Company, including customer support, operations, product development, and sales. STX is an equity trading system designed for specialists, market makers, proprietary traders, exchanges, and internalization.

The System was originally conceived, built, and maintained by a regional stock exchange to act as a front end for directed order flow, and it connected to the exchange over Selero’s order routing network, Dominet.

Today, STX is fully supported by Selero out of its Network Operation Center in Denver; customer transitions have been completed; new sales cycles are in process, and Selero has created an API for STX to facilitate interoperability with third party applications. In addition, the Company has a market-driven product roadmap. Two areas of particular interest are the integration of the System with algorithmic trading engines before year end and the productization of OTC capabilities it already supports.

Traders interested in finding out more about STX can contact Selero directly and ask for a demo.
