NYSE Pillar®

Our Integrated Trading Technology Platform

In May 2016, NYSE Group completed the rollout of NYSE Pillar matching engines on NYSE Arca. NYSE Pillar is our new integrated trading technology platform that will enable you to connect to all of our equities and options markets using a single specification. NYSE Pillar was designed to reduce complexity, while enhancing consistency, performance and resiliency.

On July 24, 2017, NYSE American successfully launched a new market model on the NYSE Pillar platform. On August 21, 2017, NYSE Arca introduced new NYSE Pillar gateways, marking the harmonization of NYSE American and NYSE Arca technology platforms. On May 21, 2018, NYSE National (the former National Stock Exchange) reopened on the Pillar Platform. On August 22, 2019, NYSE completed migration of all symbols to Pillar.


Once completely rolled out, the NYSE Pillar platform will enable you to connect to each of our markets – NYSE, NYSE American, NYSE Arca, NYSE Arca Options, NYSE American Options, NYSE Chicago, NYSE National, Global OTC and NYSE Bonds – using a single specification and will include new gateways and matching engines. This new technology offers:

  • More efficient processing
  • Shorter time to market for ongoing enhancements
  • Simplified, harmonized order types, terminology, and messaging across all of our markets
