NASDAQ Options Market (NOM)

The NASDAQ Options Market (NOM), an all-electronic, price/time priority trading system powered by INET technology, was launched in 2008. The trading system is designed to maximize liquidity, promote price competition and handle rapid order execution.

In 2011, NASDAQ OMX initiated a technical alignment between its US options exchanges and enhanced the NOM platform to improve the trading system for its customers. The enhanced platform is referred to as NOM 2.0, and benefits include common data input and output, and common interfaces, data structures and customer reporting. These changes allow customers trading on multiple NASDAQ OMX options exchanges to streamline operations. Following the adoption of NOM 2.0, the number of market makers and hence the depth of liquidity in the market increased significantly.
