U.S. Options

As previously announced in the MIAX May 10, 2017 Alert, the MIAX Exchanges intend to file rules to require MIAX Options and MIAX PEARL Members to use the MIAX Member Firm Portal (MFP) to apply same-side clearing trade corrections effective August 1, 2017, pending SEC approval.  As of August 1, 2017, MIAX Trading Operations will no longer perform this function for member firms except in the case of a system issue.

The MFP is an internet-facing portal application which provides self-service functions to member firms for applying single or bulk same-side clearing trade corrections.  Requests for price or size changes and trade adjustments or busts should continue to be submitted to MIAX Regulatory and will be performed by Trading Operations for processing. 

The MIAX Member Firm Portal is available at all times except during announced maintenance windows.  Same day clearing trade correction functionality is available during normal system hours until the end of day (approximately 5:15 PM or 2:00 PM on early closing days).

Individuals requesting Member Firm Portal access must be authorized to act on behalf of their organization.

For further information and to request access to the Member Firm Portal, please contact MIAX Trading Operations at TradingOperations@miaxglobal.com or (609) 897-7302.

Regulatory questions should be directed to the Regulatory Department at (609) 897-7309 or Regulatory@miaxglobal.com.
