ATS Order Type Entry Screen

On September 12, 2016, FINRA added a new ATS Order Type Entry Screen to the OATS Administration Section of the OATS Web Interface. Firms should note that this screen is only available in the FIRM view of the OATS Web Interface and not via the Transmitting or Reporting Firm view of the Web Interface. The ATS Order Type Entry Screen enables firms operating an ATS to register ATS Order Types with OATS, as required by FINRA Rule 4554. FINRA Rule 4554 requires that ATS Order Types be registered with FINRA at least 20 days prior to the Order Type becoming effective.

Specific Requirements

For each ATS MPID, the following information must be provided for each Order Type used by the ATS:

  1. ATS MPID that will use the Order Type
  2. Order Type Identifier assigned by the ATS to the Order Type1
  3. Description of how the Order Type operates within the ATS
  4. Effective date of the Order Type Identifier
  5. Expiration Date of the Order Type Identifier

Firms may not reuse Order Type Identifiers for the same ATS MPID.

Firms may begin entering Order Type Identifiers into the screen immediately. Firms may begin testing submission of orders containing registered Order Type Identifiers in the OATS CT Environment beginning on September 26. Please note that ATS Order Type Identifiers registered via the OATS Production Web Interface will be available in OATS CT within 24 hours.

Please contact the OATS Helpdesk at 1-800-321-6273 with any questions related to this new functionality.



1. An identifier shall not be required for market and limit orders that have no other special handling instructions outside of those permitted to be used by ATSs as described in the OATS Reporting Technical Specifications.
