3. About Me
• M. Sc. Computer Science/Physics, National
University Of Ireland
• M.Sc. Finance, London Business School
• Working in electronic FX market making for ~
10 years
• Currently working on an FX algorithmic trading
execution and liquidity management platform
4. The FX Market
• Decentralised $5+ trillion / day market
– There is no single ‘FX market’
– Cross-border, cross-regulation
• 24 hours / day, 5.5 days/week, 52 weeks / year
– 7am Auckland Monday to 5PM NYC Friday
• Main trading centres are London / US (NYC,
Chicago) / Singapore / HK / Tokyo
– 3 of the top 5 centres are in Asia
– Singapore increased its global share to ~ 8% in 2016
from ~ 5.7% in 2013
5. The FX Market
• Top traded currency
by volume is USD
• So-called ‘EM’
currencies now make
up a large percentage
of global flow
• NOTE: Gold and other
precious metals fall
under the umbrella of
FX
9. FX Infrastructure
• Most electronic trading is colocated in the
major data centres in New York, Tokyo,
London, Chicago
• Clients trade via fast cross-connects within
data centres or optical fibre networks
between continents
• Every millisecond counts!
11. What is an FX Transaction?
• Currencies are quoted for
trading purposes as A/B
– E.g. EUR/USD, USD/JPY,
AUD/USD
• Normally buy/sell currency
A in units of currency B
• A provider will ‘bid’ to buy
and ‘offer’ to sell
13. What is an FX Transaction?
• FX currency pairs can be ‘direct’ or ‘cross’
• Direct pairs are normally heavily-traded liquid instruments
• A ‘cross’ pair is one that can be created as a result of trading
two other currency pairs simultaneously
• E.g. a EURJPY price can be calculated from the output of a
simultaneous transaction in EURUSD and USDJPY
14. FX Products
• Spot: Delivery in T+2 / T+1
– Depending on currency
– Pre-spot: Delivery today (T) / tomorrow
• Forward – Delivery in T+N days
– E.g. 1 month, 3 months
• Swaps – Pair of offsetting transactions
– Normally spot + forward (or forward + forward)
– E.g. buy EURUSD spot, sell EURUSD 1 month forward
• Also: Options / futures / block trades etc

17. What Moves The Markets?
• Many schools of thought
– Macroeconomic / Microeconomic
– Interest rate differentials
– Purchasing Power Parity
– GDP
– Short-term order flow imbalance
• FX is an event-driven market
– Economic announcements and events can move the
market significantly
• Political and geopolitical Events
22. FX Market Volatility
• Volatility (V): measure of the standard deviation of
returns over a given period
• Volatility of volatility (V2): measure of how much
returns alternate between quiet and volatile changes
• The distribution of V and is V2 is increasingly skewed
• The market is becoming more ‘choppy’
Volatility of volatility 2013 2016
Instrument Mean Median Mean Median
EURUSD 6.20% 6.00% 7.00% 6.30%
USDJPY 8.10% 7.80% 8.30% 7.40%
USDZAR 11.20% 10.30% 17.00% 17.20%

Maximum USDJPY Volatility up to 1300%
30. NFP 8th July 2016
Maximum EURUSD Volatility up to 1000%
31. FX Algorithms
• A lot of FX trading is done through automated
computer-driven algorithms
– This may be a factor that exacerbates volatility spikes
• Algos fall into various categories depending on
their purpose
– Aggressive vs Passive
– Dynamic vs static
– Liquidity-seeking vs liquidity providing
– Opportunistic vs predetermined
32. FX Algorithms
• Algorithms act on input signals (e.g. prices,
volatilities, liquidity indicators and take action
• Typically will attempt to find the optimal balance
between risk and return (optimal execution)
• Minimise ‘Implementation Shortfall’ or slippage
33. FX Algorithms
• Sweep
– Aggressive strategy that tries to get liquidity by trading
across multiple liquidity pools simultaneously
– High market impact
– Sensitive to liquidity pool selection
• Iceberg
– Passive strategy that places passive orders showing only
part of the order
– When the visible part of the order is matched the algo
replenishes the amount in the market
– Low market impact
– Attempts to minimize information leakage
34. FX Algorithms
• Peg
– Keeps orders in the market at a fixed distance from a
predefined reference price
– As the reference price updates, the algo replaces the order
at the updated level
– Generally passive (but can vary)
• TWAP
– Splits a larger order into smaller sub-orders worked over a
longer execution period
– Generally low market impact, but can be more aggressive
– Designed to minimise information leakage and price
slippage
35. TCA
• Transaction Cost Analysis
• Quantifying the performance of trading algorithms against
consistent benchmark
• Used to rank trading algo performance and improve them

36. Modern Trading Challenges
• Managing market fragmentation
– Smart order routing
– Best execution and trade analysis
– Avoiding information leakage
• Managing the ‘data deluge’
– Billions of price ticks/day
– Need to be stored and analysed
– Specialised databases and analytical software
• Credit Management
• Latency and Connectivity
39. Regulatory Challenges
• The FX market is in a period of change /
evolution
• Increased regulatory constraints have placed
brakes on market activity
• Cost of compliance and credit has risen
– Banks spend a higher % on compliance than ever
• Global FX Code of Conduct being developed
• Regulation is driving automation

41. Trading Desk Roles
• Quantitative Analysts
– Use analytical tools to devise pricing, trading and risk management strategies
– Backtest and implement trading algorithms
– Mix of mathematical and programming skills
– Quants are becoming more ‘applied’
• FX (Voice) traders
– The traditional FX trader role
– Take orders directly from clients and manage order flow
– Take a limited amount of discretionary risk
• eFX Traders
– Monitor trading flow and manage client orders
– Manually intervene when required
– Adjust client pricing and analyse deal flow
– ‘execution consultants’
• eFX Sales
– Client management
– Maintain dialogue with clients
– Help clients get the optimum setup for their needs
42. Trading Desk Roles
• Liquidity Management
– Manage external liquidity provider relationships

based on the data
• Credit Management
– Maintain and set up credit lines
– Monitor credit usage
– Interface to market risk / credit risk / compliance
• Client Services
– Connectivity management
– Client queries and problem resolution
– Need detailed knowledge of client setup
48. Summary
• FX markets are evolving
– Increasing fragmentation
– New players are emerging
• Trading desks are becoming leaner and more systematic
– Manual / voice traders are becoming extinct
• The market is becoming more volatile
• The cost of credit is rising
• Technological demands are increasing
– Timescales are moving from millseconds to microseconds
• The market is becoming more automated
– Algorithms are driving a larger percentage of trading volume
• Regulation is driving change in the structure of the market
– E.g. increased automation is being demanded by regulators
• FinTech will play a role
• New opportunities are opening up!
