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. The next phase of the Pillar technology project will be the launch of NYSE American (pending SEC approval) on the Pillar platform in July 2017. NYSE Arca will follow shortly thereafter with the introduction of new NYSE Pillar gateways.


Once completely rolled out, the NYSE Pillar platform will enable you to connect to each of our markets – NYSE, NYSE MKT, NYSE Arca, NYSE Arca Options, NYSE Amex Options, 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

What You Can Expect
