TECHNICAL FIELD
[0002] The present disclosure relates to the trading of securities
or derivatives, such as options or futures. More particularly, the
present disclosure relates to an automated exchange trading system
and method for routing and matching orders.
BACKGROUND
[0003] The introduction of electronic trading mechanisms into
exchanges for securities and derivatives has been an ongoing
process. The desire for immediacy of order execution and
dissemination of information is one reason for the steady
substitution to electronic mechanisms. As trading volume continues
to grow, along with the accompanying need for an increasingly
efficient trading environment, the move toward electronic trading
mechanisms is favored.
[0004] Electronic exchanges, while efficient and nearly
instantaneous, do not necessarily provide for the routing of orders
to a trade engine for a "flash" to the virtual crowd (an
electronic, non-floor-based crowd) instead of routing to an away
exchange with a more attractive market. A flash period is an
auction period prior to the order linking away to another exchange.
It is desirable for an exchange to provide a mechanism for the
routing of orders to a trade engine for a "flash" to the virtual
crowd instead of routing to a public automated routing (PAR) system
for booking or automatically linking to an away market.
[0005] Currently, national best bid or offer (NBBO) rejects,
certain "tweeners" and orders that are marketable against away
markets route to PAR. Once on PAR, the orders are represented to
the open outcry crowd and, if not traded by the crowd, are either
routed to the book ("tweeners") or to an away market. Since manual
handling is required on a floor of an exchange for these orders and
multiple orders may arrive at a single floor-based workstation,
there can be delays between the time the order arrives on the
floor-based workstation (e.g. public automated routing workstation
(PAR)) and the time the order is routed, booked or sent away for
linkage to an away market. During the time period when an order
rests on PAR, there is risk to both the customer and the PAR
broker.
BRIEF SUMMARY
[0006] In order to address the drawbacks of both traditional open
outcry exchanges and electronic exchanges as they pertain to the
trading of national best bid or offer (NBBO) rejects, certain
"tweeners" and orders that are marketable against away markets, an
automated trading platform and method is disclosed herein routing
and matching orders from a virtual trading crowd in an exchange
prior to booking the order or automatically linking the order to an
away market.
[0007] According to a first aspect of the disclosure, an automated
system for matching orders from a virtual trading crowd in an
exchange configured for trading securities or derivatives is
disclosed including an electronic trade engine operative to receive
at least one of an order or a quote for a security or derivative at
the exchange, the trade engine further operative to disseminate a
request for a price message to a plurality of market makers quoting
a class in response to receiving the order or quote, an electronic
book in communication with the electronic trade engine, the
electronic book operative to store at least one order or quote
received by the electronic trade engine, a database including an
allocation algorithm, the database in communication with the
electronic trade engine, and a trade processor in communication
with the database, the trade processor operative to allocate orders
or quotes according to the allocation algorithm selected from the
database.
[0008] According to a second aspect of the disclosure, a method for
matching orders or quotes to a virtual trading crowd in an exchange
prior to automatically linking the order to an away market is
disclosed, the method including, receiving an order or quote for a
security or derivative at the exchange, wherein the exchange
comprises a price for the security or derivative that differs from
a national best bid or offer price, routing the order or quote to a
trade engine, disseminating a request for price message to a
plurality of market makers quoting a class, receiving at least one
response message at the electronic trade engine, initiating a quote
trigger, wherein the quote trigger occurs for a period of N
seconds, and allocating at least a portion of the order or quote to
at least one market maker according to an allocation algorithm, and
allocating a remaining portion of the order or quote, if any, to at
least one predetermined market maker guarantor to execute the
remaining portion of the order or quote at the national best bid or
offer price.

subject matter sought to be protected, there is illustrated in the
accompanying drawings an embodiment thereof, from an inspection of
which, when considered in connection with the following
description, the subject matter sought to be protected, its
construction and operation, and many of its advantages should be
readily understood and appreciated.
[0010] FIG. 1 is a diagram of one embodiment of an automated
exchange system.
[0011] FIG. 2 is a block diagram of one embodiment of the
electronic trading engine of FIG. 1.
[0012] FIG. 3 is a flow diagram of one embodiment of a method for

DETAILED DESCRIPTION OF THE DRAWINGS
[0013] A system and method for trading securities, such as
securities options is described herein. The trading mechanisms and
rules described are based on providing incentives or limitations to
particular classes of individuals or entities who are involved in
trading at an exchange. For purposes of this specification, the
following definitions will be used:
[0014] Broker/dealer--person or entity registered to trade for
itself and/or on behalf of others at the exchange.
[0015] Public customer--person or entity, who is not a
broker/dealer, trading on their own behalf through a broker/dealer
or firm registered to trade at the exchange.
[0016] Firm--entity employing persons who represent the firm, or
the firm's customers, on the exchange, such as market makers, floor
brokers, broker/dealers, or other industry professionals.
[0017] Market maker--professional trader registered to trade at the
exchange who is required to provide liquidity to a market, for
example through streaming quotes for both a bid and an offer at a
particular price.
[0018] Designated primary market maker (DPM)--market maker
designated by the exchange to be responsible for a fair and orderly
market, and to provide continuous quotes, for a particular class of
options.
[0019] Virtual crowd--an electronic, non-floor-based crowd.
[0020] In-crowd market maker (ICM)--a market maker physically
present on the floor of an exchange.
[0021] Non-ICM--any market participant other than an ICM.
[0022] Remote market maker (RMM)--a market maker not physically
present on the floor of an exchange.
[0023] Market participant--any person or entity that can submit
orders or quotes to an exchange.
[0024] Class of options--all series of options related to a given
underlying security, where the underlying security may be, for
example, publicly traded stock of a company.
[0025] Tweener--Order on a trading system that is represented to
the open outcry crowd and, if not traded by the crowd, which is
routed to the book.
[0026] Referring to FIG. 1, one embodiment of an exchange system
combining aspects of electronic, screen-based trading with
traditional, open-outcry trading suitable for implementing various
securities and derivatives trading methods described herein is
illustrated. The exchange system 10 receives order information for
the purchase or sale of securities, for example derivatives such as
stock options, from numerous sources at a central order handling
system (OHS) 12. OHS 12 may be any of a number of data processing
systems or platforms capable of managing multiple transactions, as
are well known in the art. For example, in one embodiment, the
order routing system can be implemented on a transaction processing
facility (TPF) platform manufactured by IBM Corporation. For
purposes of clarity, the examples herein will refer specifically to
options. However, it will be appreciated that the system and
methods disclosed herein might be applied to the trading of other
types of securities and derivatives.
[0027] Accordingly, an exchange utilizing the system and methods
described herein may manage a number of classes of derivatives,
where each of the plurality of classes of derivatives are
associated with an underlying asset such as a stock, a bond, a
note, a future, an exchange traded fund, an index, a commodity or
other known asset types.
[0028] Information, such as orders may be entered into the OHS 12
from remote member firm systems 14 (including remote market makers
18) and/or other exchange systems 16. The member firm systems 14
and other exchange systems 16 may be located remotely from the
geographical location of the exchange and use any of a number of
standard landline or wireless communication networks to direct
orders electronically to the OHS 12. The member firm systems 14 and
other exchange systems 16 communicate with one of several
interfaces or protocols for transmitting their orders to the OHS
12. Examples of suitable interfaces are those using a distributed
object interface based on the Common Object Request Broker
Architecture (CORBA) standard and available from the Object
Management Group. Interfaces such as financial information exchange
(FIX), which is a message-based protocol implemented over TCP/IP
available from FIX Protocol, Ltd., or other known securities
transaction communication protocols are also suitable protocols.
Potential destinations for these orders are the OHS 12 or the
electronic trade engine 24 in communication with the OHS 12.
[0029] When a trade is completed, such as a trade that is
automatically executed through the electronic trade engine 24, the
fill information is sent through the electronic trade engine 24 and
OHS 12. OHS 12 passes the fill information to the member firm
systems and to a continuous trade match (CTM) system 38 which
matches the buy side and sell side of a trade which, in turn,
forwards the matched trades to the Options Clearing Corporation
(OCC) 40, a third party organization that will verify that all
trades properly clear. The electronic trade engine 24 also sends
quote and sale update information through an internal distribution
system 42 that will refresh display screens within the exchange
system 10 and format the information for submission to a quote
dissemination service such as the Options Price Reporting Authority
(OPRA) 44.
[0030] As illustrated in FIG. 2, an electronic trade engine 24
comprises a trade processor 30 that analyzes and manipulates orders
according to matching rules 32 stored in the database in
communication with the trade processor 30, as described in
copending U.S. patent application Ser. No. 10/423,201, the entirety
of which is hereby incorporated by reference. Also included in the
electronic trade engine is the electronic book (EBOOK) 34 of orders
and quotes with which incoming orders to buy or sell are matched
with quotes and orders resting on the EBOOK 34 according to the
matching rules 32. In an embodiment, upon a match, the electronic
trade engine 24 will mark the matched order or quote with the
broker-specific identifier so that the broker sending the order or
quote information can be identified. The electronic trade engine 24
may be a stand-alone or distributed computer system. Any of a
number of hardware and software combinations configured to execute
the trading methods described below may be used for the electronic
trade engine 24. In one embodiment, the electronic trade engine 24
may be a server cluster consisting of servers available from Sun
Microsystems, Inc., Fujitsu Ltd. or other known computer equipment
manufacturers. The EBOOK 34 portion of the electronic trade engine
24 may be implemented with Oracle database software and may reside
on one or more of the servers comprising the electronic trade
engine 24. The rules database 32 may be C++ or java-based
programming accessible by, or executable by, the trade processor
30.
[0031] When a trade is automatically executed through the
electronic trade engine 24, the fill information is sent through
the electronic trade engine 24 and OHS 12. OHS 12 passes the fill
information to the member firm systems and to a continuous trade
match (CTM) system 38 which matches the buy side and sell side of a
trade which, in turn, forwards the matched trades to the Options
Clearing Corporation (OCC) 40, a third party organization that will
verify that all trades properly clear. The electronic trade engine
24 also sends quote and sale update information through an internal
distribution system 42 that will refresh display screens within the
exchange system 10 and format the information for submission to a
quote dissemination service such as the Options Price Reporting
Authority (OPRA) 44.
[0032] The exchange system 10 may be configured to incorporate
quote trigger functionality to permit greater participation in
trades. The quote trigger would automatically be invoked when a new
better price is entered so that additional market participants may
have a limited time in which to enter quotes at a price matching
the new better price and obtain a portion of the order. For
example, upon detecting a quote from a market participant at a new
best price which would match against an order on the electronic
book from a non-ICM, the electronic trade engine 24 will remove the
quantity of the resting order that would be tradeable against the
incoming quote and hold it and the incoming quote for a
predetermined period of time. Any desired preset hold period may be
used, however in one embodiment it is contemplated that a five
second hold period is used. In other embodiments, the hold period
may be fixed anywhere in the range of 0.5-5.0 seconds. After
removing the quantity of the resting order, the electronic trade
engine 24 will treat the removed quantity of resting order as
having been sold and disseminate a last sale market data message so
that the OPRA system 44 will indicate the trade has taken place.
The electronic trade engine 24 will update the top-of-the-market
(i.e. update the quote) as though the trade had immediately
occurred.
[0033] During the hold period, any other quotes or orders from
market participants that would also be marketable against the
original resting order are gathered and the resting order volume at
the current best price will be further reduced, if any still
remains in the book. At the expiration of the hold period, the
accumulated in-crowd market participant quotes and orders are
traded against the resting orders. If the size of the resting order
was greater than the size of the sum of the market participant
quotes and orders, each of the quotes and orders would execute
fully against the resting order. If the size of the resting order
is less than the sum of the market participant quotes and orders,
the resting order is allocated among the quotes and orders
according to the matching algorithms discussed above. The
electronic trade engine will then send fill reports of the executed
trades to the OHS 12 for distribution to the appropriate source of
the quotes or orders involved.
NBBO Rejects
[0034] If an incoming order is marketable, but the exchange is not
the NBBO, the OHS 12 will utilize routing parameters that permit
NBBO reject orders to route to the electronic trade engine 24 on a
class and origin basis. NBBO reject orders that are routed to the
electronic trade engine 24 will be handled as described below.
[0035] Referring now to FIG. 3, a method of providing orders to a
virtual trading crowd in an exchange prior to automatically linking
the order to an away market is illustrated. As shown, a marketable
order (an order that is marketable at an away market) for a
security or derivative is received at the exchange system 10 (step
100), the exchange system 10 having a price for the security or
derivative that differs from a national best bid or offer price.
The marketable order is routed to the trade engine 24 (step 120),
where a Request for Price ("RFP") message is disseminated
("flashing," as detailed below) to a plurality of remote market
makers 18 quoting a class (step 130), which as detailed below, can
include information such as the starting (and trading) price, as
well as the side and size of the order. At least one of the remote
market makers 18 responds to the RFP message (step 140) and
transmits a response message to the electronic trade engine 24
(step 150). The response message, which is a message indicating the
remote market makers' 18 response to the RFP message, is received
at the electronic trade engine 24 (step160), and a quote trigger is
initiated, with the quote trigger occurring for a period of N
seconds (step 170).
[0036] In accordance with an embodiment, any existing quote locks,
quote triggers or auctions for quotes and offers at the NBBO will
end and will be allocated prior to the start of any "flashing" of
NBBO reject orders to market makers quoting in the class. In one
embodiment, "flashing" is accomplished by transmitting a Request
for Price ("RFP") to the market makers quoting in the class. The
system 10 may retain a record of all market makers quoting at the
best price as well as the firm quote obligation when the RFP is
sent. This is referred to as the "flash" phase. In one embodiment,
the RFP includes the NBBO price as the starting (and trading)
price, as well as the side and size of the order. The flash phase
will last for a period of N second(s), where N may be a fixed or
variable time period, or until the first RFP response is received,
whichever is shorter. Typically, the flash phase period is the same
for any flash type described herein. In one embodiment, the
N-second period is less than 5 seconds. In other embodiments, it is
contemplated that each flash type (e.g. NBBO reject, Tweener, etc.)
may be assigned a different time period. In yet other embodiments,
the time period may be variable based on the current number of
market makers in the quoting class, the number of contracts
involved or other instantaneous or historical statistic relating to
the class of options being traded.
[0037] Unlike other RFPs, the NBBO price is not a starting price
for an auction. Instead, the NBBO is typically the price that the
order will be traded at even if a quote moves to a better price or
an RFP response is received at a better price. Essentially, the
order is treated as though it has been booked at the NBBO price. As
with other RFP responses, these will not be displayed as part of
the disseminated quote. Once the first response is received from a
market maker at the appropriate price (either a quote, or an ICM
order, also referred to as an I-order or an RFP response) the
second phase (the "trigger" phase) will be started. During the
trigger phase, a quote trigger will last for N seconds. In one
embodiment, a last sale price will be disseminated immediately.
Quotes, I-orders and RFP responses may be included in the quote
trigger group.
[0038] In one embodiment, the order will be allocated using a
matching algorithm, referred to herein as the Capped Ultimate
Matching Algorithm (CUMA). In CUMA, the allocation algorithm will
typically be configurable by class and/or by auction-type. For
example, matching algorithms can be used to allocate an incoming
order to participants based on the number of participants and the
order size each participant represents. Furthermore, orders are
preferably allocated to the multiple market participants quoting at
the same price based on two components: an `A` component, or parity
factor, and a `B` component, or pro rata/depth of liquidity factor.
The parity factor of the matching algorithm treats as equal all
market participants quoting at the relevant best bid or offer at
the exchange (BBO). Thus, if there were four market participants
quoting or bidding at the best price, each would be assigned 25
percent for the parity component of the matching algorithm. Viewed
in conjunction with the pro rata factor of the algorithm, the
parity component of the algorithm provides incentive to market
participants to quote at a better price than their competitors even
though they may have a smaller quote size than other market
participants quoting at the BBO.
[0039] The second component of CUMA rewards those quoting larger
sizes at the best price by providing the market participants a pro
rata component based on the percentage of the volume of that market
participant's quote size with reference to the sum of the total of
all quote sizes at the best price, with the added feature that
certain participants are limited in the size of their order that
will be used to calculate the `B` component of the equation. For
example, if the disseminated quote represents the quotes of market
makers x, y, and z who quote for 20, 30, and 50 contracts
respectively, then the percentages assigned under the pro rata
component are 20% for x, 30% for y, and 50% for z. The final
allocation may then be determined by multiplying the average of the
A and B components by the size of the incoming order available. In
one embodiment, the matching algorithm described above produces the
following equation:
Participant ` s allocation = incoming order size [ 1 number of
participants + participant quote size participant quote sizes 2 ]
##EQU00001##
[0040] Thus, for example, where certain participants are limited in
the size of their order that will be used to calculate the `B`
component of the equation, participants such as in-crowd market
makers (ICMs) may be capped in this way so that, after other
participants have already entered their order or quotes, the ICM
cannot inflate the size of its order to obtain a greater pro rata
weighting (and thus greater allocation) of the available order.
[0041] Additionally, all responses (including quotes, I-orders and
RFP responses) from a single market maker will typically be
aggregated for the purposes of calculating the `A` component of
CUMA. A participation filter may be used by the trading engine to
determine which market participants can or cannot participate in
the quote trigger. For example, the electronic trade engine may be
configured to permit all non-customers to participate in the quote
trigger process by recognizing a participant identifier associated
with non-customers. In other implementations the electronic trade
engine may be programmed to only allow ICMs to participate in a
quote trigger.
[0042] If non-customers were included in the quote trigger process
based on this filtering mechanism, an incoming order under the `B`
component could start the quote trigger after the RFP period is
started. Additionally, an incoming `B` component of the order would
participate in the quote trigger, rather than trading at the next
price. It is anticipated that customers will continue to trade as
they do today.
[0043] In another embodiment, the order will be allocated using
another matching algorithm, referred to herein as the Maker-Taker
Algorithm. Under the Maker-Taker Algorithm, all trades are divided
into two types of orders: price setter and price taker. Traders who
want to buy or sell at a given price place a price setter order,
and traders who want to interact with the bid or offer place a
price taker order. Often, the price setters receive a rebate when
their orders are executed, while the price takers are charged for
order execution. There is no customer priority of orders in
connection with this algorithm.
[0044] Once the flash phase begins, if a marketable customer order
is received that could trade against the flashed order, the orders
will trade against each other immediately with any balance routing
to the appropriate destination. If a customer order is received
during the trigger phase, it may trade at the next available price
or route to the appropriate destination.
[0045] If the away market moves during the flash phase and the
exchange becomes the NBBO, the flash phase will end and the order
will be automatically traded and allocated to the market makers on
the quote. If an away market moves to a better price during the
flash phase, the flash phase will end and the order will route for
auto-linking to an away exchange. Since market makers may have a
firm quote obligation during the N-second flash phase, if the
exchange market makers move quotes such that there is no longer
enough size to fill the incoming order up to the original
disseminated size, the order will be routed to an away exchange
immediately using auto-link functionality.
[0046] If the flash phase ends and there are no responses, the
order will automatically link away from the exchange to another
exchange. In the unlikely circumstance that the order cannot be
routed away once it is received due to either: (1) a lack of an
away market at a better price, or (2) the OHS 12 rejects that order
because the away market is no longer available after the system 10
attempts to send the linkage order, the system 10 will
automatically route the order back to the electronic trade engine
24 where it will be filled at the original firm quote price up to
the original firm quote size.
[0047] In one embodiment, the order may be filled in one of the
following ways:
[0048] If there are market makers on the market that can fulfill
the firm quote obligation (the original price and size or better)
the order will be assigned to them. Alternatively, if there is more
size required to fulfill the firm quote obligation, the order will
be assigned to those quoters who comprised the firm quote at the
time the order was received. Since the electronic trade engine 24
will have to keep track of the participants that were on the
original market, it is contemplated that an additional mechanism
may be required so that the electronic trade engine 24 does not
have to store the information indefinitely.
[0049] In one embodiment, a market maker guarantor may be
designated to fill orders not fully executed (and therefore have a
remaining portion). Such a designated market maker guarantor
assures that there will be an NBBO execution for the remaining
portion of orders from a submitting firm that are not fully
executed after the exposure and allocation periods have concluded
(detailed above). There may be one or more predetermined market
maker guarantors and each market maker guarantor may set parameters
33 on their execution guarantees including but not limited to order
size, price, size of a displayed national best bid or offer, which
exchanges are displaying the national best bid or offer,
transaction costs, and a number of increments from an exchange best
bid or offer. Market maker guarantors may set only one or any
combination of these parameters 33, which parameters 33 may then be
stored in a database of the exchange system 10. The market maker
guarantor designations 35, i.e. the market makers designated as
guarantors, and the parameters 33 set by the market maker
guarantors may both be stored in a guarantor database 37 in
communication with the trade processor 30, as detailed herein
above, so that the trade processor 30, in communication with both
the rules database 32 and the guarantor database 37, can be
operative to analyze and execute orders according to the allocation
algorithm selected from the rules database 32 and allocate a
remaining portion of the order, if any, to at least one
predetermined market maker guarantor selected from the guarantor
database 37 to execute the remaining portion of the order at the
national best bid or offer price.
[0050] Preferably, the remaining portion of the order is
automatically allocated to the market maker guarantor if the
remaining portion meets the parameters 33 set by the market maker
guarantor. A notification may be sent by the exchange system 10 to
the market maker guarantor upon the automatic allocation of the
remaining portion of the order. It is also contemplated that, in
the event that the remaining portion of the order exceeds the order
size that a market maker guarantor is willing to guarantee, the
remaining portion of the order may be divided among more than one
market maker guarantor so that the entire remaining portion may be
executed at the NBBO. Alternatively, it may be desired that, if the
remaining portion of the order exceeds the order size that a market
maker guarantor is willing to guarantee, the remaining portion is
not executed against the market maker guarantor.
"Tweener" Locks
[0051] An incoming order that is between the market at the
exchange, but is marketable against an away market, is commonly
referred to as a "tweener lock." The "tweener lock" order cannot be
booked because it would lock or cross an away market. In one
embodiment, the OHS 12 comprises routing parameters to allow
tweener locks to route to the electronic trade engine 24 based on
class and origin. Orders that are routed to the electronic trade
engine 24 will typically be handled as described above for NBBO
rejects, with the exception that there is no firm quote obligation.
Thus, the requirements of the firm quote will typically not be
followed. If there are no responses during the flash phase, the
order will be automatically linked away. If the order cannot be
linked away, it will automatically route back to the electronic
trade engine 24 for booking.
"Tweeners"
[0052] An incoming order that is between the market at the exchange
and does not lock or cross an away market is commonly referred to
as a "tweener." In one embodiment, the OHS 12 comprises parameters
used to route tweeners to the electronic trade engine 24 based on
class and origin code. Orders that are routed to the electronic
trade engine 24 will be handled as described above for NBBO
rejects, with the exception that there is no firm quote obligation.
Thus, the requirements of the firm quote will not be followed. If
there are no responses during the flash phase, the order will
typically be booked automatically.
[0053] Although the system and methods described herein relate to
an exclusively electronic, screen-based exchange that does not
include floor based, open-outcry trading, many of the procedures
described may be applied to a system incorporating and involving
active participation from a trading floor and a screen-based
electronic trading crowd. As will be appreciated by those of
ordinary skill in the art, mechanisms for providing orders to a
virtual trading crowd in an exchange prior to booking the order or
automatically linking the order to an away market and other
features described above may all be modified for application to
other forms of trading within the purview and scope of the present
invention. An advantage of the disclosed system and methods is that
more traders at the exchange may have more opportunity to see and
compete for orders that are NBBO rejects, tweener locks or
tweeners, thus increasing visibility of orders and the desirability
of maintaining a presence at the exchange.
[0054] The matter set forth in the foregoing description and
accompanying drawings is offered by way of illustration only and
not as a limitation. While particular embodiments have been shown
and described, it will be apparent to those skilled in the art that
changes and modifications may be made without departing from the
broader aspects of applicants' contribution. It is therefore
intended that the foregoing detailed description be regarded as
illustrative rather than limiting, and that it be understood that
it is the following claims, including all equivalents, that are
intended to define the scope of this invention.
