High-Frequency Trading (HFT) is the nuclear energy of the finance industry. The smartest bankers on the planet have armed themselves with bleeding-edge technologies from ultra-high-performance computers to ultra-low-latency networks to exotic things they find lying around at CERN. Not only has financial regulation come under stress from their activities, but even the physical limitation of the speed of light is bitterly lamented for the problems it causes (or praised by innovators for the opportunities it creates).
HFT allows fortunes to be made or lost in minutes, and the Flash Crash last year bounced the US stock market so hard that the solution was to turn the financial markets off and on again to make the problem go away. But without HFT markets might not function as efficiently, and if taken away from the UK would cost many jobs. So have we signed a Faustian bargain for our financial souls, or are opponents of modern trading Luddites who long for a time when gentlemen brokers passed pieces of paper around Edwardian coffee houses?

Dave Cliff is Professor of Computer Science at the University of Bristol. In 2001, he published the first results showing that computers could automate not only the trading process, but also the process of designing and/or fine-tuning trading algorithms and market mechanisms within which traders interact. Following an article on his work in The Economist in November 2002, he spent two years working with HP to develop his research into real applications for tier-one financial institutions. In 2005, Dave moved to Deutsche Bank’s FX trading floor in London, then co-founded Syritta Algorithmics Ltd, a trading technology development and consultancy firm, and later served as Professor of Computer Science at the University of Southampton. Dave is author/co-author on over 70 academic journal or conference publications, inventor/co-inventor on 15 patents and numerous further patent applications currently under review. He has given well over 100 invited keynote lectures and seminars, he and his work have frequently been featured both in the press and on TV and radio, and his work has been the topic of articles in New Scientist, Financial Times and The Economist. Dave currently serves on the committee of the UK government Foresight Project whose role is to evaluate HFT and how it may be best regulated.
