OTC Bulletin Board (OTCBB)

The OTC Bulletin Board (or OTCBB) is an interdealer quotation system that is used by subscribing FINRA members to reflect market making interest in OTCBB-eligible securities (as defined by FINRA Rule 6530). Subscribing market makers can utilize the OTCBB to enter, update, and display their proprietary quotations in individual securities on a real-time basis. Such quotation entries may consist of a priced bid and/or offer; an unpriced indication of interest (including "bid wanted" or "offer wanted" indications); or a bid/offer accompanied by a modifier to reflect unsolicited customer interest. Members that submit quotes in OTCBB-eligible securities to the OTCBB must comply with the Rule 6400 and 6500 Series, as well as all other applicable rules and regulations.
