Tick Size Pilot Program

Overview

On June 24, 2014 the SEC issued an order directing that the national securities exchanges and FINRA (collectively, “SROs”) to act jointly to develop and file an NMS plan with the SEC to implement a pilot program to study the impact of wider quoting and trading increments on trading of certain small capitalization stocks. On May 6 2015 the SEC approved an amended Tick Pilot NMS Plan. The Pilot will be two years in length. Market participants will be required to collect data to ensure the impact of the pilot can be properly studied. Data collection for the pilot will begin on April 4, 2016, 6 months prior to the implementation of the trading and quoting rules for the pilot. Implementation of the trading and quoting rules for the Pilot will begin in October 2016. For more information please see the additional resources to the right.
