Regulatory Notice 17-22
FINRA Adopts Rules on Disruptive Quoting and Trading Activity and Expedited Proceedings
In December 2016, FINRA implemented two new rule changes regarding disruptive quoting and trading activity. The first rule change adopts new Supplementary Material .03 to Rule 5210 (Publication of Transactions and Quotations) to explicitly define and specifically prohibit for purposes of Rule 5210 two types of quoting and trading activity that are deemed to be disruptive. The first type of activity involves a party entering multiple limit orders on one side of the market that changes the level of supply and demand for the security, entering one or more orders on the opposite side of the market that are subsequently executed, and, following the execution, canceling the original limit orders. The second type of activity consists of a party placing an order inside the national best bid and offer, and then submitting an order on the opposite side of the market to execute against another market participant that joined the new inside market.
The second rule change amends the FINRA procedural rules regarding temporary cease and desist orders (TCDOs), found in the Rule 9800 Series, to create a process for FINRA to issue, on an expedited basis, a permanent cease and desist order against a respondent that engages in a frequent pattern or practice of the disruptive quoting and trading activity in Supplementary Material .03 to Rule 5210.
