TIS101 INTRODUCTION Issue 14 Copyright 2006 London Stock Exchange plc 7 SECTION 1 INTRODUCTION 1.1 The Service Definition This document provides an overview of the Exchange's trading and information services. The systems are based on an open architecture and generic business infrastructure. All Exchange information and trading systems are accessed through three common interfaces using standard data formats and are delivered via the Exchange's network. This allows flexibility to adapt rapidly to future trading requirements.The three generic interfaces are:
- the broadcast interface - for bulk delivery of information to subscribers
- the interactive request interface - for re-requesting broadcasts from our information service and for Own Order Book downloads and Own Trades Order Book download (OTBD)
- the secure interactive interface - for entering transactions to the Exchange’s trading system. Please refer to TIS102 (Interface Specification) for detailed information of these interfaces. Trading The following trading Services are currently available on the Exchange’s trading system:
- UK equities - ordinary shares issued by UK companies, traded on the order book of SETS and SETSmm, the quote-driven trading service of SEAQ, the quote and order driven service of SETSqx and the International Retail Service
- International equities - there are currently both Global Depositary Receipts (‘GDRs’) and American Depositary Receipts (‘ADRs’) traded on the International Order Book. International equities are also trading on ITBB, mostly from Asia. This service is segmented into ‘ISD regulated’ and ‘non-ISD regulated’ segments. EUROSETS is an order-driven trading service offering a competitive secondary market trading in liquid, large and mid-cap Dutch equities
- AIM securities - shares and fixed interest stocks of companies admitted to the AIM market, quoted on SETSqx, SEAQ and SETSmm
- UK gilts - securities issued by the UK Government, traded by Gilt-Edged Market Makers (GEMMs)
- Sterling bonds - issued by companies or local authorities, quoted on SEAQ
- Eurobonds and medium-term notes - issued by UK and international companies
- Covered warrants - a warrant issued by a party other than the issuer or originator of the underlying asset
- Depositary receipts - negotiable certificates traded on the International Order Book
- Exchange traded funds - Simple, low-cost and flexible investments that track indices and sectors in the UK, US and European markets
- INTRODUCTION TIS101 8 Copyright 2006 London Stock Exchange plc Issue 14
- Exchange traded commodities - dedicated SETSmm market segment for products such as oil and gold bullion and supported by registered market makers providing liquidity. Information All broadcast data is currently disseminated to subscribers via Infolect. This delivers significant benefits to customers, reinforcing our commitment to provide extensive and high-quality market data services. Infolect provides a number of broadcast services that disseminate order and quote details, trade reports and added value information. Subscribers have the flexibility to choose the broadcast services that meet their individual requirements without having to subscribe to them all. Section 3 provides a description of each of the broadcast services in detail. 1.2 Service Changes This guide has been amended to incorporate all service changes made since September 2005, including the introduction of TradElect TM , SETSmm expansion, FTSE classification changes, the introduction of Exchange traded commodities and the decommissioning of Broadcast Data Groups (BDGs). 1.3 Readership The Service Definition is intended for Technical personnel who require an overview of the Trading and Information Services and an understanding of how to implement the services within their organisation. The Service Definition should be read in conjunction with the Exchange's other technical specifications: Interface Specification (Ref: TIS102), Network Specification (Ref: TIS103) and Data Formats (Ref: TIS104). The Exchange may also publish updates to the technical information contained in this document via Service Announcements. These are available on our website http://www.londonstockexchange.com/en-gb/products/membershiptrading/techlib /servannounce/serviceannouncements.htm 1.4 Enquiries Please contact the Technical Information Desk if you require further copies of this document or related documentation. The Technical Information Desk should also be contacted if you have technical enquiries about the trading and information services. All enquiries should be addressed to: Technical Information Desk 2 nd Floor London Stock Exchange 10 Paternoster Square London EC4M 7LS Telephone: +44 207 797 3939 or STX 33939 Questions may also be submitted via e-mail to: CTGroup@londonstockexchange.com 1.5 Web Site The technical documentation is available on the technical library of the London Stock Exchange Web Site.
- Market Segments
- Market Segment Rules
- Market Sectors
- Tradable Instruments in Market Segments
- Member in Segment
- Period Rules These components are described in more detail in Section 3 of the Interface Specification (Ref: TIS102).
In summary, the Exchange has the ability to configure a number of system rules which, when applied, allow for flexible trading environments. This approach allows for the combination of sets of different rules (governing, for example, trade publication, minimum and maximum quote and order sizes, execution rules) into market segments, so that different market segments can be established and operated according to different conventions, as market and regulatory conditions require. The architecture and application components that deliver the infrastructure of the trading system, and the secure interactive interface across which access is provided, combine to form the basis of all the Exchange's trading services.
All of the trading services are provided from a single technical platform, across a single interface, and can only be accessed remotely across this interface.
The trading facilities within the system provide scope for combining system functions in a range of different ways that can be used to provide additional trading services - or to refine existing ones as the demand arises.
- Messages are authenticated
- Requests cannot be cancelled
- Each request has a single response
- The Exchange system may send unsolicited messages For more information about the trading interface please refer to Interface Specification document (Ref: TIS102).
Participants log-on to the trading system via the secure interactive interface and submit request messages. Each request message from a participant is immediately authenticated and if authentication is successful, acknowledged by a response message. In addition, the Exchange system is able to send the participant unsolicited messages that relate to events within the trading system affecting the participant, for example, execution of an order the participant had previously entered. The participant must acknowledge the unsolicited message on receipt.
The response messages are returned on the same connection as the request message was sent.
Response messages will be returned as the Exchange completes the processing of a particular message. These responses may be returned in a different sequence from that of the original request messages. The message reference number allows the participant to match the response with the corresponding request message. If there are multiple active connections for the same USAP then unsolicited messages will be spread across them.
- TIS101 TRADING SYSTEMS AND SERVICES Issue 14 Copyright 2006 London Stock Exchange plc 11 2.4 SETS – Service Content The SETS order book on TradElect TM , includes the FTSE 100, the most liquid FTSE 250 securities, equities that have a LIFFE traded equity option. The order-driven trading system helps to meet the needs of today's market users and plays a vital part in maintaining London's position as Europe's leading financial centre. It ensures that London is equipped to handle the huge and growing volumes of business that are transacted on its markets - allowing market users to trade efficiently and cost-effectively. Order Types There are three different types of order that apply to SETS on TradElect TM
- limit order - a priced persistent order which will remain on the order book until it expires, is deleted or is fully executed against incoming orders
- market order - an unpriced persistent order which will remain on the order book until it expires, is deleted or is fully executed against incoming orders. Market Orders are only enabled for entry in the call period of an auction Please note that all un-priced orders left on the book after the uncrossing process has completed are automatically removed prior to continuous trading beginning
- Iceberg order - a priced persistent order that will remain on the book until it expires, is deleted or is fully executed against incoming orders. Participants must populate the price, ‘total’ size and ‘peak’ size. The peak size is the volume of the order that is visible and appears to the market as a limit order. It will always be less than or equal to the total size of the Iceberg order. The total size minus peak size equals the amount of volume that is hidden from the market. When a peak is fully executed it is replaced by a new peak from the hidden volume until the iceberg is fully matched, modified or deleted.
The AD version of the 5EO Enter Order message uses a market mechanism to identify a combination of both the order type (eg Limit Order), and its execution type (eg Fill or Kill - Aggressive Type B). The new AE version of the 5EO Enter Order message explicitly uses a new ‘Validity Type’ field to describe the execution constraints of an order. Validity can be categorised into three different types; execution based validity (eg Execute and Eliminate), time based validity (eg Good Till Time) and period based validity (eg at the close).
Both limit and market orders are persistent and are displayed anonymously.
Please note that all un-priced orders left on the book after the uncrossing process has completed are automatically removed prior to continuous trading beginning. They are displayed anonymously. Incoming orders, which can only be submitted by SETS participants, are executed against them. Orders are executed in strict priority of price and time so that, at a given price, the oldest orders are executed first. The new Period based validity type introduces the concept of Parked Orders, allowing both the entry and removal of the order to be based upon a specific period based transition. An order submitted by a Participant will be held in the system until the applicable period is reached, at which point it is passed onto the order book.
Whilst the order is held by the system it is not publicly visible and does not participate in continuous trading/auctions. However, it may still be modified and deleted. Whilst parked, the order will maintain time priority in line with all other orders that have been parked for that particular instrument. Also, when modified, it follows the same rules as it would on the order book to determine whether price/time priority is maintained. As the period becomes effective the order will be ‘injected’ into the order book as if the Participant had at that point submitted the order themselves. The order will then either execute against any valid orders or remain on the book.
The transitioning of the period can also control the removal of the
TRADING SYSTEMS AND SERVICES TIS101 12 Copyright 2006 London Stock Exchange plc Issue 14 order, if it has not already been fully executed. Validity types such as ‘At the Open’ (ATO) will be entered at the start of the Auction Call period and if not executed, removed before transitioning into continuous trading. Orders may be modified by changing the absolute price and/or the relative size of the order. The current system will also allow the modification of an order’s Participant Reference, Date/Time Validity and/or Client Reference without also having to change either the price or size, or losing time/price priority.
An incoming order may execute against many orders on the book. Trades generated from automatically executed orders are published immediately and automatically. No separate trade report is required. The information presented here and throughout the remainder of section 2 is meant to give a brief outline of the trading services that are available on our systems. Readers should refer to our ‘Guide to Trading Services’ document for a more in depth understanding of how these services operate. 2.5 SETSmm – Service Content SETSmm is similar to the SETS order book. The main difference is that price formation centres around a central order book with registered market makers entering Enhanced Executable Quotes providing two-way prices during the mandatory trading period (08:00 – 16:35).Market makers are obliged to provide prices and liquidity throughout the trading day according to the same principles as today on SEAQ. SETSmm is the London Stock Exchange’s trading service for Mid Cap, Small Cap, Dual Listed Irish Securities and the constituents of the AIM 50 index. By combining the best features of the existing SETS and SEAQ trading services, SETSmm appeals to market users who want to trade electronically, as well as those customers who use the market making system. 2.6 SEAQ – Service Content SEAQ provides an automated quotations service for domestic UK securities not included in SETS, SETSmm or SETSqx. In common with all the trading services, access to SEAQ is via the secure interactive interface and it supports the following key functions:
- Quote entry, maintenance and closure by registered market makers using enhanced quotes with a ‘FQ’ market mechanism
- Trade report entry and correction The service continues to support the operation of the competing market maker mechanism in the UK.
The FQ enhanced quote provides the convenience of a single message for submission of a two-way price and does not interact with the order book in any way and is treated purely as a price display mechanism. Registered market makers are also able to close individual quotes or all quotes in a market segment. SEAQ supports the entry of trade reports in domestic securities. All delayed trade processing is automated, so that block trades can be reported electronically to the Exchange and an electronic pre-release facility is provided to allow participants to automate the early release of block trades when unwound according to the Exchange's rules.
TIS101 TRADING SYSTEMS AND SERVICES Issue 14 Copyright 2006 London Stock Exchange plc 13 2.7 SEATS PLUS - Service Content This service will no longer be available when TradElect TM goes live. These securities will be transferred to SETSqx as part of the Exchange’s commitment to align it's trading services. For more information please refer to the SETSqx service and technical description available at: http://www.londonstockexchange.com/NR/rdonlyres/88F86AF1-24B2-407E-953B-09B A305CE1CE/0/SETSqxServiceTechnicalGuide.pdf 2.8 SETSqx – Service Content SETSqx will have similar functionality to the SEAQ quote based market model with the addition of an order display facility that periodically uncrosses (to enable compliance with MiFID requirements).
Unlike SETS and SETSmm, this service is not designed to support continuous order book trading. Market makers will continue to provide non-electronically executable quotes and liquidity throughout the trading day according to the same rules as on SEAQ. Today brokers either need to phone market makers or use their proprietary RSP systems to execute their business. SETSqx will additionally offer the opportunity to enter orders into the central trading system so satisfying MiFID limit order display requirements and provide the option to set their own price. Both named and anonymous order entry are supported by SETSqx.
2.9 International Order Book – Service Content The International Order Book is a fully electronic, ‘SETS style’ trading service provided by the London Stock Exchange to support trading in Global Depositary Receipts and American Depositary Receipts. The International Order Book is a trading service operated by the London Stock Exchange and is available to all member firms. The International Order Book supports all SETS order types with the addition of a named order type. Named orders make use of the Committed Principal (CP) order type to identify the participant behind the order. Named Orders work similarly to a limit order on the order book.
These orders can only be input in a principal dealing capacity. All other order types are able to execute against a named order.
Certain sectors within IOB are auction only sectors. In these sectors continuous execution is disabled and the order operates as a continuous auction call with three uncrossing periods a day. These are currently at 11:00, 14:00 and 15:40.
- Market makers will replace liquidity providers and provide prices in European and US bluechip securities in sterling
- All securities are quote-driven
- Settlement will take place in CREST Depositary Interest (‘CDI’) form at the domestic UK tariff
- Full coverage of the following indices: NASDAQ 100, AEX, SMI, CAC40, DAX30, MIB30, Eurostoxx 50, FTSE Eurotop 100, DOW JONES IA 30 (excluding Walt Disney) This service is split into 'ISD regulated' and 'non-ISD regulated' segments. This differentiation has been introduced to allow for clear identification of those securities captured by the suite of directives being implemented over the next few years as part of the European Union’s Financial Services Action Plan (FSAP).
Securities admitted to trading in the ISD regulated segments will be, in the main, those with a listing with an EU competent authority. These securities will become subject to the suite of FSAP Directives as they are implemented over time. Securities which are not listed within the EU need not be admitted to a regulated market and will not be subject to European (ISD) regulation. Note that there is no difference in the operation of the ISD and non-ISD regulated segments, and the differentiation is not applied to the trading day model. It is purely a mechanism for the differentiation between securities that are subject to different levels of European regulation.
For more information on this service please refer to our Guide to Trading Services, available at http://www.londonstockexchange.com/NR/rdonlyres/C50E4770-12CE-4FB7-8058-075 2C44F790F/0/GuideToTradingServicesv70.doc 2.11 International Bulletin Board The International Bulletin Board (ITBB) is part of the International Order Book (IOB) market offered by the Exchange for equity trading. Whilst offering the same advantages of electronic execution as that of IOB, this mechanism also offers the opportunity for participants to register as Market Makers to support trading liquidity.
Certain sectors within ITBB are auction only sectors.
In these sectors continuous execution is disabled and the order book operates as a continuous auction call with three uncrossing periods a day. These are currently at 11:00, 14:00 and 15:40. Unlike IOB which uses Named Orders, ITBB uses the new 5EQ Enter Enhanced Quote messages. The enhanced quote can continue supporting the existing (nonexecuting) firm quotes in addition to the new functionality as follows. The enhanced quote provides the convenience of a single message for submission of a two way price, but has the added advantage of treating the two prices as individual executable objects.
This results in behaviour more closely resembling an order, and makes it possible to choose whether the quote is executable or not. This is achieved through the ‘Market Mechanism Type’ that must specify either ‘EQ’ for an executable quote or ‘FQ’ for a (nonexecutable) firm quote.
- a pre-trade, “price-orientation” period between 8:05 and 8:15. Executable Enhanced Quotes can be entered or deleted during this period.
- a Mandatory Committed Principal period from 8:15 – where market participants can only enter aggressive orders, executing against Executable Enhanced Quotes, for US based warrants the mandatory period starts at 14:45, however execution is enabled from 08:15 for aggressive order types
- if the underlying security on which the warrant is based is subject to a temporary suspension of automatic execution, the warrant will not be suspended
- all markets close at 16:30 with the exception of European based warrants where the market closes at 16:00. However if Executable Enhanced Quotes are still open after 16:00 in these European warrants full execution of aggressive order types is enabled. Closing prices for European warrants will be frozen at 16:00 and not 16:30.
- after the market close, all Executable Enhanced Quotes will be automatically deleted.
Please refer to the Covered Warrant Technical Guide on the London Stock Exchange Web site for additional information. 2.13 Exchange Traded Funds Exchange Traded Funds (ETFs) give private investors the chance to buy whole indices as easily as buying a share on the London Stock Exchange. This creates real opportunities – widening the reach of portfolios and making top-down investment more cost-effective. For brokers, ETFs also present a growing opportunity – to offer an attractive new product that trades and settles in exactly the same way as shares.
ETFs are in the ETFS segment which is a SETSmm type environment.
This allows price formation around a central order book with registered market makers entering executable enhanced quotes providing two-way prices during the mandatory trading period (08:00 – 16:45). All business executed via the ETFS order book will be covered by the existing Central Counterparty (CCP) Service for Equities with settlement netting. 2.14 Exchange Traded Commodities The trading mechanism for ETCs is the same as the ETF segment in every respect and will support products such as gold bullion and oil. Trades will be cleared by the clearer.
- the sharing of reference data
- local time conversion
- access to the systems on public holidays Additional market specific functionality will also be supported where required. The Exchange supports the JSE Ltd (“JSE”). Trading on the Namibian Stock Exchange (“NSX”), for whom the JSE currently provide technology, is also supported by the LSE.
A detailed Market and Trading functionality overview for the JSE and NSX markets can be found at: http://www.jse.co.za/jse_initiatives/jsetrad_info_sys/tradindex.htm 2.16 Own Order Book Download – Service Content Participants are able to download details of all their own orders currently held on the central order book. Order details in all relevant trading services are transmitted via the interactive interface in ascending order code sequence. This facility provides opportunities for reconciliation of central and local order book details, and provides scope for full recovery in the event that a participant should lose all or part of their order book held on their own systems.
This service uses the Interactive Request Interface. This interface is briefly described in section 3.3. For detailed information please refer to the Interface Specification TIS102. The interactive request interface allows subscribers to log-on to the Exchange's system and submit interactive request messages. The Exchange system supports re-requests of broadcast messages by subscribers through the Message Retrieval service. To use the Own Order Book Download service, the user must be a market participant. A market participant is a user entering information, for example limit orders. The responses to the request message details all orders that the participant had open on the Exchange's Order Book at the time of the request.
- Date: The request must be for a trade date that is within the period that trades are stored on the trading system – currently 3 working days. This is a mandatory field.
- Instrument: The request may be specific to a particular instrument, which if used must include the Country of Register and Currency Code.
- Trade Status: The request may specify trades of a particular status; if it is matched, cancelled or awaiting cancellation.
- Execution Type: The request may specify to include automatic trades, manual trades or both.
- Client Reference Code: The request may specify a client reference code. Manual trades will only populate the first 15 characters of this 30 character field.

TIS101 BROADCAST SERVICES – INFOLECT Issue 14 Copyright © 2006 London Stock Exchange plc 19 SECTION 3 BROADCAST SERVICES – INFOLECT 3.1 Introduction This section presents an overview of the information feed and interfaces that make up the Exchange’s Information system and then gives a description of each of the Broadcast services that are currently available over this feed. 3.2 Information Feed – Infolect Broadcast services are currently provided to subscribers over the Exchange’s digital information feed known as Infolect. Subscribers to these services are able to receive broadcasts and re-request messages.
The information disseminated over the broadcast feed by the Exchange is divided into a number of logical services. Each service consists of one or more service channels, with each service channel being made up of one or more message types. Messages are broadcast in real-time, as they are generated.
JSE customers use Broadcast Data Groups instead of Service Channels. Subscribers receive broadcast and interactive data on the same physical line up to the maximum bandwidth that has been configured for that subscriber. Broadcast data and Interactive services do not affect each other. Service Channels are recoverable. Authorised subscribers are able to request the re-transmission of any missed broadcast message using the Message Retrieval service (see Interactive Request Interface in the Interface Specification, TIS102 guide).
Messages in Broadcast Services In order to reflect the flexibility of the trading system service channels are structured to include all messages it would be possible to use, given the range of trading functionality available.
However, not all messages within a service channel will be used at any given time. The messages that can be sent down each service channel are detailed in later sections. Additional information on individual messages is detailed in the Data Formats document (Ref: TIS104).
BROADCAST SERVICES – INFOLECT TIS101 20 Copyright 2006 London Stock Exchange plc Issue 14 3.3 Interfaces used for the Broadcast Services Bulk delivery of information to subscribers is provided via the Broadcast Interface. Please refer to Section 1 of the Interface Specification guide TIS102 for more details of this interface. Subscribers can re-request broadcast messages via the Interactive Request Interface. Please refer to Section 2 of the Interface Specification guide TIS102 for more details of this interface.
The interactive request interface allows subscribers to log-on to the Exchange’s system and submit interactive request messages.
The rerequest of broadcast messages by subscribers is supported through the Message Retrieval service. Market participants may request details of all their open orders using the Own Order Book Download service. Market participants may request details of all their trades still residing on the trading system using the Own Trades Book Download service. Each request message from a subscriber is immediately acknowledged by a reply message. The reply may be followed by a sequence of further messages, which are not acknowledged by the subscriber. In addition, the subscriber is able to cancel a request that has not been completely processed.
If a number of request messages are sent in, only one is satisfied at a time. The subscriber can assign a priority to each request message. The message priority is used to determine which of the subscriber's requests to satisfy first. If two request messages have the same priority, they are processed in the order in which the Exchange receives them. A more recent higher priority request message is processed before any lower priority requests are completed. Broadcast data is controlled and enabled by the Exchange and will never run beyond the bandwidth supplied to a customer by the Exchange.
Interactive traffic is dependent on the volume of request messages submitted by a subscriber and the bandwidth available.
