NYSE Pillar

Pillar introduces a standardized wire protocol for connectivity to exchange matching engines and Securities Information Processors (SIPs) operating on the platform.

The Pillar platform supports the matching engines of multiple exchanges, including NYSE, NYSE Arca, NYSE American, NYSE Chicago, and NYSE National. It also serves as the backbone for the Pillar SIP platform, which transitioned from its legacy architecture on July 26, 2021. This migration brought significant improvements in latency to the Options Price Reporting Authority (OPRA) and introduced a new binary protocol based on the Pillar wire protocol.
