EQUITY MARKETS ADVISORY COMMITTEE No. 4-01
RE: SEC ORDER APPROVING NASDAQ SUPERMONTAGE PROPOSAL
The Securities and Exchange Commission has issued an order approving Nasdaq’s
proposed Order Display Facility and Order Collector Facility as well as modifications to the
Nasdaq trading platform (referred to as “SuperMontage”).1 In addition, the SEC is soliciting
comments on, and at the same time has granted accelerated approval to, Amendment No. 9 to
the proposal.2 A copy of the Release is attached.
SuperMontage was initially published for comment in December 1999.3 Since that time,
in response to concerns expressed by commenters, the proposal was amended and published
for comment three more times.4 The Institute filed several comment letters on SuperMontage.5
These letters expressed support for the objectives of SuperMontage, in particular, increasing the
transparency of limit orders in the Nasdaq market and the ability of those orders to interact
with one another. The letters, however, also expressed concerns regarding various aspects of
the proposal. Those concerns, and Nasdaq’s and the SEC’s response to those concerns, are
summarized in the following description of SuperMontage as adopted.
1 Securities Exchange Act Release No. 43863 (January 19, 2001), 66 FR 8019 (January 26, 2001) (“Release”).
2 Amendment No. 9 specifies how preferenced orders (discussed below) will be processed. The amendment also
makes a technical correction to the definition of preferenced orders and represents that Nasdaq will not use OATS
data to gain an unfair competitive advantage over other market participants. Comments on Amendment No. 9 are
due to the SEC no later than February 16, 2001.

2Background
As noted above, SuperMontage will consist of a new Nasdaq Order Display Facility and
Order Collector Facility. The Order Display Facility will display the best bid/best offer in
Nasdaq and two price levels away from the best bid/best offer, in addition to the aggregate size
at each price level of the “displayed” trading interest of market makers, ECNs, and UTP
Exchanges. Nasdaq market makers and ECNs that are NASD members (“Nasdaq Quoting
Market Participants”) will be able to display their quotes/orders anonymously at these price
levels in the Order Display Facility. The Order Display Facility also will allow Nasdaq Quoting
Market Participants to provide the Nasdaq system with multiple agency and principal
quotes/orders at single, as well as multiple, price levels.
Nasdaq Quoting Market Participants will be required to designate a quote/order as
“attributable” or “non-attributable,” and will be able to indicate a reserve size for the
quote/order.6 If an order is “attributable,” the price and size of the order will be displayed next
to the Nasdaq Quoting Market Participant's market maker ID (“MMID”) in the Nasdaq
Quotation Montage if this is the Quoting Market Participant's best-priced attributable order.
Attributable orders or quotes would be displayed in the Nasdaq Order Display Facility as part
of the aggregate trading interest when the price of the quote/order is within the best three price
levels in Nasdaq.
If a Nasdaq Quoting Market Participant designates a quote/order as “non-attributable,”
it will be displayed in the Nasdaq Order Display Facility as part of the aggregate trading
interest when the price of the quote/order is within the best three price levels. That order or
quote would not, however, be displayed in the Nasdaq Quotation Montage next to the Quoting
Market Participant's MMID.
SuperMontage also will consist of an Order Collector Facility that will serve as a single
point of order entry and single point of delivery of liability orders and executions.7 To access
the best-priced quotes/orders, a market participant will be required to enter an order into the
Order Collector Facility, which will deliver either an automatic execution or a liability order to
the next Quoting Market Participant in the queue based on SuperMontage’s order execution
algorithms. By creating the Order Collector Facility as the single point of order entry and the
single point of delivery of executions and orders, Nasdaq believes that SuperMontage will fully
integrate its two current trading systems, SelectNet and SOES, from the end user's perspective.
Order Execution Algorithms
SuperMontage will replace Nasdaq's current SOES and SelectNet services with two new
processes: a directed order process and a non-directed order process.
6 The “reserve size” function allows a Nasdaq market maker or ECN to display publicly part of the full size of its
order or interest with the remainder held in reserve on an undisplayed basis to be displayed in whole or in part as
the displayed part is executed.
7 A “liability order” means an order to which an ECN, market maker, or UTP Exchange specialist owes a firm quote
obligation under Securities Exchange Act Rule 11Ac1-1.
31. Directed Order Process
The directed order process will be functionally similar to the current SelectNet service in
that it will allow a Nasdaq participant to direct an order to a particular Nasdaq Quoting Market
Participant or UTP Exchange. A directed order can be a liability order or a non-liability order.
However, to avoid creating a risk of double liability, a Nasdaq Quoting Market Participant or
UTP Exchange will not be required to receive directed liability orders through the Order
Collector Facility.
2. Non-Directed Order Process
A non-directed order is an order that the market participant does not route to a
particular Nasdaq Quoting Market Participant or UTP Exchange, or a preferenced order
(discussed below). Upon receipt of a non-directed order that is not a preferenced order, the
Order Collector Facility will determine the next Nasdaq Quoting Market Participant or UTP
Exchange in the queue due to receive an order based on one of three order execution algorithms
and deliver either an execution or a liability order, depending on how the Nasdaq Quoting
Market Participant or UTP Exchange participates in Nasdaq.
As originally proposed, SuperMontage would have executed non-directed orders
entered into the system in general price/time priority. Within a price level, however, the
system would have executed non-directed orders first against the displayed quotes/orders of
market makers and ECNs that participate in the automatic-execution functionality of the system
(“Auto-Ex ECNs”), then 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 have executed against reserve size of market makers and
Auto-Ex ECNs, and then reserve size of Order-Delivery ECNs. Finally, the system would have
executed against the quotes of UTP exchanges.
In response to concerns expressed by commenters on the original proposal, the NASD
eliminated the distinction between automatic execution participants and order delivery
participants and, instead, proposed to give ECNs that do not charge a separate quote access fee
priority over ECNs that do. After receiving comments on this proposed change, the NASD
amended the proposal to give market participants that enter non-directed orders a choice as to
how their orders will be executed. In particular, orders in SuperMontage will be executed
based on one of three order execution algorithms: price/time priority; price/time priority
considering ECN access fees; or price/size/time priority. The price/time priority algorithm
will be the default algorithm for non-directed orders.8
a. Price/Size/Time Priority
The Institute and other commenters objected to the proposed price/size/time algorithm.
The Release specifically notes the Institute’s concerns that (1) granting size priority ahead of
time priority would negate the incentive for price improvement, (2) the price/size/time
algorithm would offer little, if any, benefit because, under the other two algorithms,
8 The SEC notes in the Release that although none of the three order execution algorithms maintains pure price/time
priority, they afford price/time priority to a wider range of orders than is currently available in Nasdaq.
4participants would still have the ability to sweep through all orders at a given price level, and
(3) participants could instead utilize the directed order process to send an order to a participant
displaying greater size.9
The Release states that the SEC concluded that the algorithm based on price/size/time
priority is consistent with the Exchange Act as it will assist market participants in quickly
assessing liquidity in a dynamic trading environment, while rewarding liquidity providers,
particularly in a decimals environment where liquidity may be spread over a greater number of
trading increments. The SEC acknowledged concerns raised by commenters, including the
Institute, that the choice of algorithms lessens the importance of time priority, and therefore
may provide less incentive to aggressively enter better-priced quotes. The SEC, however, notes
that the three algorithms afford greater price/time priority than currently exists in the Nasdaq
market.
In addition, the SEC states that because it does not believe that entering orders into
SuperMontage should be mandated, requiring time priority within SuperMontage runs the risk
of reducing a market participant’s willingness to enter orders into SuperMontage, therefore
undermining the effectiveness of the system. For this reason, the SEC believes that providing
the choice of a price/size/time priority algorithm is a statutorily-permissible balance between
encouraging liquidity, accommodating the preferences of market participants, and maintaining
time priority. The SEC also states that while this algorithm may reduce the incentive to be the
first with the better price, it may encourage a Nasdaq Quoting Market Participant to display
greater size.
b. ECN Fees
The NASD proposed to give market makers and ECNs that do not charge a separate
access fee priority over ECNs that do. The Release states that commenters were split on this
issue with some believing it was appropriate to give the orders of ECNs that do not charge fees
priority because the ECNs that charge fees provide an inferior execution price. Others,
however, argued that ECNs frequently offer a better price than market makers at the BBO even
after access fees have been deducted from the execution price.
In response to commenters, the NASD amended SuperMontage to provide investors
with the order execution algorithm choice that considers access fees. In addition,
SuperMontage was amended to provide parity to ECNs that charge access fees when the price
improvement on a particular quote/order at least equals the access fee under the price/time
priority option that takes ECN fees into account.
The Release notes the Institute’s support for the NASD's elimination of the per se
treatment of ECN access fees but also said that several commenters, including the Institute,
nevertheless supported executions based on strict price/time priority.
9 The Institute supported the two algorithms that follow price/time priority because they would resolve the dispute
over how to treat ECN access fees within SuperMontage while maintaining adherence to the principle of price/time
priority.
5The SEC found that the price/time algorithm that takes ECN access fees into account is a
reasonable attempt to allow market participants to access the quote of an entity that does not
charge fees before directing their orders to an ECN that charges fees because the quote/order of
an ECN that charges an access fee may actually result in an inferior execution price after the fee
is added. In addition, the Release states that the NASD’s decision to retain the algorithm that
accounts for ECN access fees does not unfairly discriminate against ECNs, particularly because
market participants may choose either of the two other algorithms that do not consider ECN
fees.
Preferencing and Amendment No. 9
Amendment No. 8 to the SuperMontage proposal introduced a new class of orders into
SuperMontage called “preferenced orders,” which will allow a market participant to designate
a particular quoting market participant against which its order is to be executed or delivered.
Preferenced orders will be processed in the same queue as non-directed orders and will be
considered liability orders. When a preferenced order is next to be executed within the non-
directed order queue, SuperMontage will execute against both the displayed quote/order and
the reserve size of the preferenced quoting market participant. Any unexecuted portion will be
returned to the entering market participant.
Two possible approaches to preferenced orders were proposed in Amendment No. 8:
Alternative A, which would provide for preferenced orders with no price restrictions and
Alternative B, which would provide for preferenced orders only at the BBO. In response to
commenters objections, including those of the Institute, that allowing market makers to
preference orders away from the BBO would give them the ability to trade with each other and
ignore better-priced quotes/orders offered by other participants, the NASD withdrew
Alternative A in Amendment No. 9 and chose Alternative B as the approach by which
preferenced orders will be processed.
The Institute opposed the introduction of preferenced orders into SuperMontage
because, among other things, allowing market participants to send preferenced orders inside
the SuperMontage system would undermine the concept of price/time priority by allowing
market participants to preference market participants that lack priority status, and thus damage
the integrity of the Nasdaq market. In addition, the Institute stated that it is likely that such
orders could be used as a mechanism to facilitate such practices as internalization and payment
for order flow.
In response to these concerns, the SEC noted, among other things, that preferenced
orders are just one of the delivery options available to market participants and that market
participants also may send directed orders, non-directed non-preferenced orders, and orders
outside the SuperMontage (via private links). In addition, the SEC states that it is highly
unlikely that orders subject to payment for order flow will be preferenced through
SuperMontage rather than routed directly to market makers. Finally, the SEC states that while
it recognizes that preferenced orders do not create as strong incentives to quote aggressively in
SuperMontage as would strict price/time priority, there is substantial doubt whether these
orders would be entered in SuperMontage at all without the preferencing feature.
6Internalization
Under all three order execution algorithms, when a Nasdaq Quoting Market Participant
is at the best bid/best offer, Nasdaq will provide for internal matching of that participant’s
orders against the participant's quotes/order before the order is sent into the Nasdaq system to
execute against all non-directed orders.
The Release notes that the Institute opposed SuperMontage’s internalization function
and specifically notes that the Institute believed that the internalization of orders could impede
access to liquidity and price discovery for market participants, especially if a significant amount
of a particular security's daily volume is internalized.
In response to comments opposing internalization, the Release states that market makers
currently internalize order flow without ever providing access to any other market participants
and that it is unlikely that market makers will enter customer market orders into SuperMontage
rather than simply internalizing them directly. Nevertheless, the internal matching function
attempts to encourage market makers to enter these orders into SuperMontage where superior
quotes would have some chance of interacting with them. The SEC therefore believes that the
SuperMontage's internalization function is a reasonable attempt to encourage Nasdaq Quoting
Market Participants to include their customer orders in a system that will provide greater
transparency and accessibility to other participants, and could lead to a more transparent and
seamless integration of internalizing market makers with the rest of the marketplace.10
Reserve Size
As noted above, the reserve size function of SuperMontage allows a Nasdaq market
maker or ECN to publicly display part of the full size of its order or interest, with the remainder
held in reserve on an undisplayed basis to be displayed in whole or in part as the displayed part
is executed. In response to a commenter’s suggestion on the original proposal, in Amendment
No. 4 to SuperMontage, the NASD added the "size/time priority" characteristic to the reserve
size function to provide order execution priority for orders with the larger displayed size (after
being refreshed out of reserve).
The Release notes the Institute’s concerns with this proposal, particularly that the
size/time prioritization of reserve size would discourage market participants from displaying
orders greater than 1,000 shares. In response to these concerns, the SEC states in the Release
that two requirements should ensure that market participants continue to have an incentive to
display their quotes/orders. First, market participants must display a minimum of 1,000 shares
to use the reserve size feature. Second, all displayed quotations at the same price level in the
SuperMontage generally will have priority up to their displayed size over all reserve size at the
same price level. In addition, the SEC states that market forces and competition may encourage
10 The SEC reiterated, however, that its approval of this aspect of the proposal is based on the structure of the existing
dealer market and the voluntary nature of the SuperMontage. In addition, the SEC states that while a broker does
not necessarily violate its duty of best execution by internalizing its agency orders, the duty also is not necessarily
satisfied by routing orders to a market center that merely guarantees an execution at the national BBO without taking
into account the possibility of price improvement.
7Nasdaq Quoting Market Participants to display greater size if the price/size/time algorithm is
widely used. The SEC therefore concluded that Nasdaq’s use of the reserve size feature is
reasonable and could result in increased depth and liquidity in Nasdaq.
Preservation of Time Priority for Size Increases to Quotes/Orders
As proposed, a market participant that changed its displayed trading interest by
increasing its displayed size would lose its priority status in the SuperMontage order execution
queue. In response to concerns expressed by commenters on this aspect of the proposal,
including the Institute, the NASD modified SuperMontage to protect the time priority of these
market participants. Specifically, under SuperMontage, quote entries will receive a time stamp
which will be used in determining their ranking in the execution algorithm relative to other
quotes/orders at that price level. If a market participant increases its displayed size, the system
will maintain the original time stamp for the original quantity, protecting its time priority, and
assign a separate timestamp for the increased portion. Decreases in size will be deducted from
individually-stamped components in reverse time priority, i.e., the last entered size component
will be exhausted first.
Five-Second Interval Delay Between Price Levels
As originally proposed, after displayed and reserve size is exhausted at a particular
price level, there would be a five-second interval delay before SuperMontage would attempt to
execute an order at a new price level. The Institute questioned this provision, specifically
whether the proposed five-second delay would reduce volatility in the markets as intended.
In response to these comments, Nasdaq amended SuperMontage to include a more
limited interval delay parameter. In particular, the system limits the five-second interval delay
to situations where an order is partially filled at one price level, and the remaining shares of the
order will not be filled in full at the next two trading increments away. In these situations, there
will be a five-second interval delay or pause before the order moved to the next increment away
from the original increment. In addition, a market participant will be able to set a parameter on
an individual order so that the order will trade through all displayed and reserve interest at the
three price levels being displayed in the Order Display Facility at the time of entry, without
pausing five seconds in between each displayed price (“Sweep Order”). However, a Sweep
Order may only execute through a maximum of the two price levels displayed in the Order
Display Facility (and into the third price level). If the Sweep Order is not executed in full at the
third price level, the order will pause for five seconds between each subsequent price level.
The Release notes that the Institute, in its comment letter on the amended proposal,
supported the limited five-second interval delay between price levels and the proposed Sweep
Order parameter, but also notes the Institute’s uncertainty over whether the NASD’s
modifications to the process went far enough to address concerns about imposed trading
delays. Despite these concerns, the SEC concluded that the two exceptions to the five-second
interval delay between price levels provide a reasonable compromise between the need for fast
executions and the need to provide market participants adequate time to manage their capital
risk by monitoring and updating their quotes. In addition, the SEC expects that the NASD will
monitor market performance in the SuperMontage as it relates to the five-second interval delay,
particularly the potential for queuing, and consider modifying that time period, if necessary.
8Finally, the SEC believes that the delay could help stabilize the market during periods of
volatility by allowing Nasdaq Quoting Market Participants and UTP Exchanges the opportunity
to monitor and assess their quotes in a reasonable manner in response to changing market
conditions.
Issues Relating to Competition
The Release notes that many commenters were concerned that SuperMontage would be
anti-competitive either because, in their view, the SuperMontage will implement a monopolistic
execution system that will compel participation by NASD regulated broker-dealers, and in turn
stifle ECN innovation and diminish market competition, or that the automatic execution feature
of the SuperMontage will force order flow into the SuperMontage. In addition, the Release
notes that many commenters raised issues that relate to the multiple roles that the NASD has as
an SRO and, through Nasdaq, as an exclusive processor of market information and as an
operator of trading facilities.
In response to these concerns, the NASD agreed to provide an alternative quotation and
transaction reporting facility for NASD members, including ATSs, ECNs, and market makers,
that will permit NASD members to comply with their obligations under SEC and NASD rules
without participating in SuperMontage. The NASD represented that the facility will be
available upon the implementation of SuperMontage. The SEC states it believes that this
undertaking by NASD, in conjunction with other terms applicable to the NASD’s interaction
with the SuperMontage, provides an appropriate balance of NASD’s role as regulator of the
OTC market and its role as operator of an execution service in a competitive market.
Implementation Date
The Release states that Nasdaq intends to implement SuperMontage as soon as
practicable after decimal pricing is fully implemented in Nasdaq. According to the Release,
Nasdaq plans to phase-in Nasdaq securities similar to the way the SEC’s Order Handling Rules
were introduced, i.e., initially implement the system for a limited number of securities (e.g., 100
stocks) representing a cross-section of Nasdaq-listed stocks and, on a regular basis thereafter,
add 100 new stocks until the system is implemented for all Nasdaq-listed securities.
