The Investors Exchange LLC (IEX) has proposed a rule change to include DEEP+ data in its HIST Data Product. DEEP+ is a new real-time data product that provides detailed information on individual displayed orders and execution data, while HIST offers historical data. The initiative aims to increase transparency by adding DEEP+ data to HIST without altering existing rule language. The Securities and Exchange Commission has identified the proposal as non-controversial and, waiving the 30-day waiting period, allowed it to be effective from December 9, 2024.
Simple Explanation
IEX is adding more detailed and real-time data called DEEP+ to its history data collection to help people see more about how trades happen on the market. The change was approved quickly because it wasn't seen as something that could cause problems.
