U.S. Equities

As previously announced in the March 18, 2021 and April 27, 2021 Alerts, MIAX Pearl Equities (EPRL) published updated MIAX Express Order (MEO) Interface and FIX Order Interface (FOI/FXD) specifications to support Minimum Qty and Reserve orders. A new supporting document for Liquidity Indicator Codes is also available.
 
Implementation of these updated specifications are mandatory regardless of a firm's intention to utilize the new order types since there are additional messaging changes.

Important Dates

• The new features are currently available in EPRL Firm Test Bed (FTB2)
• The new features are targeted to be available in production on July 1, 2021
• Firms will have until the evening of July 30, 2021 to upgrade to the above specification versions. Older versions will not be supported beginning Monday, August 2, 2021.

An updated version of the Order Type Combinations Guide that includes Minimum Qty and Reserve orders is published under MIAX Knowledge Center.

Please review the updated EPRL Interface Specifications and the MIAX Exchange Group Connectivity Guide for further details.
