NYSE’s multi-year migration to its Pillar integrated trading platform is onits final leg as the exchange operator prepares for the mid-year launch of its NYSE Pillar Gateway.

The platform enables users to connect to NYSE’s equities and options markets using a single platform.

“It provides our clients with more efficient processing, shorter time to market for ongoing enhancements, and simplified, harmonized order types, terminology and messaging across all our markets,” a spokesperson told Markets Media.

As part of the rollout, NYSE will introduce new functionality across its markets and infrastructure in phases over the next three months to prepare for the Tape A Pillar launch.

The new capabilities will be available on NYSE National, NYSE American, and NYSE Arca beginning April 8, April 15, and May 13 respectively. For NYSE B/C and Tape A Shadow, NYSE Pillar Gateways, and NYSE Tape A Production, the dates are April 29, June 3, and July 15.

“The rollout plan was designed to minimize client disruption and manage risk,” said the spokesperson. “We have already completed the migration of NYSE Arca, NYSE American, NYSE National, and Trading Tapes B and C on NYSE.”

The exchange operator has published updated details on new functionality regarding auctions, order handling, gateways, market, data, and other general issues.

NYSE has made the new functional changes available in its Pillar certification test environment for all of the securities listed on the NYSE, NYSE American, NYSE Arca, and NYSE National Markets.

Clients can access the NYSE Pillar certification environment via their existing certification sessions.
