6160. Multiple MPIDs for Trade Reporting Facility Participants
• • • Supplementary Material: --------------
.01 FINRA considers the issuance of, and trade reporting with, multiple MPIDs to be a privilege and not a right. A Trade Reporting Facility Participant must identify the purpose(s) and system(s) for which the multiple MPIDs will be used. If FINRA determines that the use of multiple MPIDs is detrimental to the marketplace, or that a Trade Reporting Facility Participant is using one or more additional MPIDs improperly or for other than the purpose(s) identified by the Participant, FINRA staff retains full discretion to limit or withdraw its grant of the additional MPID(s) to such Trade Reporting Facility Participant for purposes of reporting trades to a Trade Reporting Facility.
.02 Any FINRA Trade Reporting Facility Business Member that chooses to publish aggregate daily trading volume for transactions executed within an ATS "dark pool" (defined for purposes of this Rule as an ATS that does not display quotations or subscribers' orders to any person or entity either internally within the ATS dark pool or externally beyond the ATS dark pool (other than employees of the ATS)) and reported to the Trade Reporting Facility will base such volume solely on transactions reported by the ATS dark pool for purposes of publication. The Business Member will prominently disclose that its web site may not reflect 100% of the volume for any given ATS dark pool and interested parties must consult all Business Members' web sites for purposes of obtaining an ATS dark pool's total volume.
A member's dark pool transaction data will not be included in the published volume unless the member affirmatively opts in to have its data included. A member operating an ATS dark pool must certify in writing to FINRA that (1) the member is affirmatively opting in for purposes of having its dark pool transaction data included in the published data and acknowledges that its data may be presented as an overall percentage volume only or may be broken down by security; (2) the member meets the definition of ATS dark pool above; and (3) the member has obtained a separate MPID that will be used exclusively for reporting all transactions executed within the ATS dark pool as required by paragraph (c) of this Rule.
