Alternative Display Facility (ADF)

The Alternative Display Facility (ADF) is an SRO display only facility that is operated by FINRA. The ADF provides members with a facility for the display of quotations, the reporting of trades, and the comparison of trades. The ADF best bid and offer and trade reports are included in the consolidated data stream for Nasdaq and CQS listed securities.

As an SRO display only facility, the ADF does not provide automated order routing functionality, execution facilities, or linkages between ADF trading centers. ADF trading centers are required by FINRA rule to provide direct electronic access to all other ADF trading centers and provide such access to all FINRA members that request it. All FINRA members in good standing are eligible to participate in the ADF, pending execution of appropriate contracts and meeting specific requirements as set forth by FINRA.

Currently, there are no active quoting ADF participants.
