AGENDA
• The new exchange participants• Architectural Differences• ATS system architecture• Challenges to the industry

1. The participants
4
Industry Trends – exchange participants
• Global brokers• Simple connections, FIX• Routing networks• Co-location• Cheapness• Product expansion
• Commodities, Derivative, ETFs.
• Local Brokers• No changes• Cost reduction • Simplicity
• Algo Traders:• Cheap • Fast• High volume/low latency • Co-location• Simple market structures• Out of hours trading• Not afraid of technology!

Industry Trends – effect on execution centres
• In 2003 trend was• BCR centric – resilience and recovery key• High degree of functionality – derivatives, ETFs etc• Multi-asset/functionality systems• Scalability – Moore’s law kept up with increase in business
• In 2009 trend is• Low latency• Performance• High order to trade ratio• Competitive costs – low overheads

1. Architectural differences
Industry Trends – Architectural Types
7
• TT has identified four major types of architecture for exchange trading systems.
Type1. Mainframe/minicomputer centralised trading system2. Distributed multi-server resilient system3. Simple (simplex) trading system with few or no
resiliency components4. Web/windows component systems
• These are generally in order of chronological development• There is no judgment as to which is better or worse• The packages such as CLICK, X-STREAM and SAXESS are type
2• The ATSs tend to be a type 3, which has emerged as the
highest performance system due to its simplicity

Speed = simplicity...
11
Industry Trends – Trading systems
• ATS model – simple systems• Designed for speed first, resiliency
second• Sacrifice resiliency components for speed• Reliant on more stable platforms
• HP x86 Blade servers• Clustering• Disk RAID/SAN resiliency
• Use of Multicast core to architecture• Use of native protocols plus ITCH OUCH• Standardised on
• C++, • RedHat Linux, • Open source components, • MYSQL or Oracle
• Offer Co-location

Trading system latency
• Note these are “published” latency figures • Beware lies, damned lies and Exchange statistics!• Beware also that all technology providers will claim sub nano-second latency...• ASX is spending money on upgrading ITS• BATS and Chi-X will not be standing still on latency• Will Latency matter once all venues are under 1ms?

Industry Trends – effect on execution centres
• Added together, 86% of business in the top 25 exchanges goes through an ECN-style system
16
Industry Trends – Effect on execution centres
• In a theoretical world, and with routing, with all exchanges offerings being equal, market share will tend towards 25% (if there are four participants)
• “Starbucks” comparison• Thus the market will become saturated...
Industry Trends – Business Strategy
• Saturated market competition mode is thus• Minimal overheads• Maximum automation• Maximum business throughput• Possible cross-subsidy of main business streams
(e.g. listings and market data to subsidise trading)
• IT a core role• Needs to be minimal

Summary – future state architecture?
• Has the time between trading system redevelopment shrunk?• Used to be 10 years
• Designed for speed first, resiliency second• Fewer resiliency components – be brave!• Use of Multicast core to architecture• Use of native protocols plus ITCH OUCH• Standardised on
• C++, • RedHat Linux, • Open source components, • MYSQL or Oracle
• Offer Co-location
