• Order Imbalance during auction calls
• Stamping VWAP in Execution Reports of Orders & Quotes
• Stop and Stop Limit Orders
• Market to Limit Orders
• Cancel on disconnect
• Named Orders
• Cross Orders & BTFs
7

8. Reliability – Hot-Hot Architecture
• Focus on reliability vs performance – target 400 us
• 3 market partitions (equities, bonds, warrants) + trade reporting & after hours
• MIT synchronous mode was chosen for implementing a hot-hot configuration
• The system runs in a hot-hot configuration in a distributed and synchronous
mode in the PDC an SDC
• Every system’s component is running on 2 instances in PDC and in SDC for a
total of 4 instances per each component (hardware and software)
• Customers are able to access both sites cuncurrently; network failover is
automatic and transparent
• For latency reasons, SDC was moved from Turin to Milan
8

9. Reliability – MIT Synch mode
• PDC and SDC are synchronized at transaction level. Every transaction is
committed on both sites before the ack is returned to clients
• Market data is disseminated by each site independently
• Each single logical or physical component, market partition, or the full site
can failover independently and automatically to SDC in a completely
transparent way
• The system is able to automatically recover:
 the fail of any primary hardware or software system component of PDC
 the fail of any primary AND secondary hardware or software component
 the fail of one or more single market partitions
 the fail of the entire PDC
 the partial or full fail of SDC without impacting PDC
• The system guarantees no loss of trades or orders

14. Benefits of the Convergence
• Customers and ISVs have one protocol for all the equities markets  costs for
Customers can be reduced
• Functionalities developed for one market can be re-used for other markets  better
time to market & product development cost can be shared
• Each market can maintain its own market model  no need to harmonize
• Releases can be deployed at predefined time windows for all markets  improvement
of Customers planning and budgeting
• MIT has one Exchange release to maintain for all markets  Implementation cost
efficiency
• Same Technology Operations team can operate different markets in different
geographical locations  Operational cost efficiency
14

15. Additional enhancements
• New Business requirements - These include:
o iceberg order enhancements
o optional self-execution prevention
o visible or hidden indicator on passive order Execution Reports.
• Group Ticker Plant Integration (GTP) – Changes will be introduced into the
MIT Exchange system in order to be tightly integrated with the new version
of the GTP system. Thanks to hardware accelerated components, GTP 2 will
be able to disseminate tick by tick price increments (L2 market data) faster
than the current ITCH market data feed.
• Group Trading Interface Integration (GTI) – Ahead of planned availability
of new interface for actual use in December 2013, we need to build a
connection into the matching engine. Release 8 provides this link which,
when activated, will allow GTI to run initially in parallel to the existing Fix
and Native Gateways.
15

16. Additional Enhancements – continued
• Backward Compatibility of Client Facing Interfaces – In order to minimize the
changes that clients have to implement, the client facing interfaces will be made
backward compatible for specifically agreed gaps.
• New Operational requirements – Specific Market Operations requirements will be
introduced as part of the scope of this release (for example, halting instruments
across multiple days, enhance the Order Query functionality in the Service Desk
tool, introducing Members Mnemonics, etc). These are intended to improve the
efficiency of the Market Operations team.
• Enhancements to the MIT Surveillance system – The release will complete the de-
coupling of the MIT Surveillance system from the Trading system. This will allow for
greater flexibility in the implementation of future Surveillance releases.

26. Introducing the Group Trading Interface
• The Group Trading Interface (GTI) will provide our customers with a single trading interface allowing
them to manage their orders across the existing LSEG cash and derivative markets.
• The project will be delivered in a phased approach as clients move across to the new interfaces in as
short as time period as possible.
– Q4 2013 Phase 1- covering the LSEG cash markets (LSE, Turquoise and Borsa Italiana)
– Q2 2014 Phase 1.1- Introducing Prescriptive Order Routing strategies within LSEG markets
– Q3 2014 Phase 1.2- Expand the GTI coverage to Derivatives
– Q4 2014 Phase 2- The new service will connect into the GTP and become “market data aware”,
allowing order routing strategies. FPGA technologies will be introduced to improve performance.
• Customer Benefits
– Single order entry API/Session to access all markets, driving lower technical/development costs, and/or
lower third party fees from EMS/SOR vendors
– Operational efficiencies through unified symbology, common risk-controls, common
reporting/reconciliation, etc.

30. Introducing the new Sponsored Access
• Exchange participants (Members) are allowed to provide trading access to
non-exchange members through their membership. However Members must
demonstrate that they have adequate risk controls measures set up to prevent
these Sponsored participants (i.e. non-exchange members) from trading
beyond a limit the member can be financially responsible for.
• Borsa Italiana requires Members to enforce these risk control mechanisms.
• In order to support the above mentioned requirements Borsa Italiana wants to
introduce the Sponsored Access functionality which supports validations and
other features required by Borsa Italiana Trading System to allow Sponsored
Access trading.
• Borsa Italiana should provide to the Clients a Sponsor Portal that allows, via
GUI, the configuration in real time of all the parameters needed to manage
the risk control mechanism.
30

31. New Sponsored Access validations
The following risk validations are required by Borsa Italiana:
• Price Band Validation – Prevent orders from Sponsored Users with an overly aggressive
price from entering the order book and trading.
• Maximum Gross Consideration – Prevent Sponsored Users from trading beyond a threshold
specified in a configurable currency (e.g. Euros, Great Britain Pounds etc). The gross
consideration is the sum of all trades and value of all open orders of the current trading
day.
• Maximum Order Value – Prevent orders (limit and market) with an uncommonly large
order value from entering the order book.
• Maximum Order Quantity – Prevent orders from Sponsored Users with an uncommonly
large order size from entering the order book.
• Order Capacity - Prevent orders from Sponsored Users with an unexpected Capacity of
the order.
• Account Type - Prevent orders from Sponsored Users with an unexpected Account Type of
the order.
• Restricted Instrument List – With this feature, the Sponsor User would be able to update
their Sponsored Users’ restricted instrument lists.
• Maximum Message Rate – it’s requested, as technical requirement, to validate that the
incoming rate injected by the Sponsored User does not exceed the Maximum Message
Rate (number of transactions per second) configured by the Sponsor User.

35. Conclusion
• LSEG continues to lead in trading systems performance thanks to its
Millennium IT low latency technology
• Performance is relevant, however other aspects can make the difference
between success and failure. We have seen only some of them:
1. Functionally rich systems to support the launch of new products
2. Top reliability
3. Architecture flexibility
4. Market data consolidation (GTP)
5. Market access standardization (GTI & GSPO)
6. Efficient development and operational models
• LSEG is active on each one of these fronts as it is on Performance to continue
to improve the quality of our services
