NASD Proposes Rule Change Amending Order Display and Trading Proposal
Washington, DC, April 5, 2000 - The Securities and Exchange Commission (SEC) has published for comment a proposed rule change filed by the National Association of Securities Dealers, Inc. (NASD), through its wholly-owned subsidiary, the Nasdaq Stock Market, Inc. (Nasdaq), amending certain aspects of its original proposal to establish the Nasdaq Order Display Facility and to modify the Nasdaq trading platform. Comments on the proposed change are due to the SEC no later than April 20, 2000.
In particular, in response to comments on the original proposal, Nasdaq is proposing to amend, among other things, (1) the five-second interval delay between price levels and (2) the order execution algorithm as it relates to ECNs, UTP Exchanges, and displayed size refreshed from reserve. Nasdaq also stated that it is working to address concerns regarding Nasdaq technology, competition, system roll-out, and any other relevant comments.
Five-Second Interval Delay Between Price Levels
As originally proposed, if all trading interest is exhausted at a
particular price level, there would be a five-second interval delay
before the system would attempt to execute an order at a new price
level. The Release states that commenters believed the proposed
five-second interval delay between price levels was too long and/or
unnecessary for liquid stocks and could cause queuing of orders
within the system. In response, Nasdaq is proposing that the system
have a more limited interval delay parameter, providing a balance
between the need of institutional investors and market
professionals for speed and greater price continuity for individual
investors.
Processing of Non-Directed Orders
As originally proposed, the system would execute non-directed
orders entered into the system in general price/time priority.
Within a price level, however, the system would execute
non-directed orders against displayed quotes/orders of market
makers and ECNs that participate in the automatic-execution
functionality of the system (Auto-Ex ECNs), within time priority of
this class of market participants. The system then would execute
against the displayed quotes/orders of ECNs that participate in
order-delivery (Order-Delivery ECNs). After displayed size of
Nasdaq market makers and ECNs was exhausted, the system would
execute against reserve size of market makers and Auto-Ex ECNs, and
then reserve size of Order-Delivery ECNs. Lastly, the system would
execute against the quotes of UTP Exchanges.
In light of concerns expressed by commenters, Nasdaq is proposing to change the order execution algorithm with respect to ECNs. In particular, Nasdaq believes that all ECNs (who are NASD members), market makers, and non-attributed UTP Exchange agency interest, at a given price level, should be executed against in strict time priority, unless an ECN charges a fee to non-subscribers for accessing its quote. ECNs that charge an access fee should be executed after non-attributed UTP Exchange agency interest, market makers, and ECNs who do not charge an access fee because such a fee represents an increase in trading costs and therefore an inferior price. Nasdaq believes that any other prioritization would be inconsistent with the statutory mandate of providing investors with best execution of their orders.
Reserve Size
The Release states that one commenter suggested that when displayed
size is completely exhausted, quotes/orders refreshed out of
reserve size should be accessed in a slightly different manner than
described in the original proposal. Specifically, the commenter
suggested that after the displayed size of market participants
quoting at the same price level is exhausted simultaneously and
then displayed size is refreshed from reserve, the system should
establish a quoting market participant's priority to receive
non-directed orders based on the new size of the displayed quotes
(instead of the market participant's time of original quote/order
entry) with time priority governing as to any two market
participants at the same size. Nasdaq is proposing to amend the
filing to incorporate this approach into the order execution
algorithm as it believes it is logical to reward Nasdaq Quoting
Market Participants displaying greater size.
Order Execution Algorithm
Based on the proposed changes to the system, Nasdaq is proposing to
amend the order execution algorithm to execute non-directed orders
entered into the system as follows: (1) displayed quotes of market
makers, ECNs that do not charge a quote-access fee to
non-subscribers, and non-attributable agency quotes of UTP
Exchanges, in time priority between such participants; (2)
displayed quotes of ECNs that charge a quote-access fee to
non-subscribers, in time priority between such participants; (3)
reserve size of market makers and ECNs that do not charge a
quote-access fee to non-subscribers, in time priority between such
participants; (4) reserve size of ECNs that charge a quote-access
fee to non-subscribers, in time priority between such participants;
and (5) principal quotes of UTP Exchanges, in time priority between
such participants.
