The MIAX PEARL Options Exchange has published updated Interface Specifications to add clarity to the Additional Text field.  

• MIAX Pearl: MIAX Express Orders (MEO) V2.0a
  • Added clarity to the field "Additional Text" in A-R Order and Standard Order
    • The field must not contain Alphanumeric content with embedded spaces
    • The field will accept a NULL in the 1st byte and as a result will treat the content as entirely space filled

• MIAX Pearl: Clearing Trade Drop (CTD) V1.2b
  • Added clarity to the field "Supplementary ID" in Trade Message to show that “Additional Text” of MEO orders will be reflected in it

Please review the updated interface specifications for further details:
