The Exchange represents that Pillar is an integrated trading technology platform designed to use a single specification for connecting to the equities and options markets operated by Arca and its affiliates, New York Stock Exchange LLC and NYSE MKT LLC. NYSE Arca Equities will be the first trading system to migrate to Pillar. [ 6 ] The Exchange states that during the first phase of Pillar implementation, it will roll out the new technology platform over a period of time based on a range of symbols. [ 7 ] Because orders entered in symbols not yet migrated to Pillar would continue to operate under current rules, the Exchange will keep its current rules, pending complete migration of symbols to Pillar and retirement of the current trading system, and will add new rules that would be applicable to symbols that trade on the Pillar trading platform.
