High-Frequency Trading: A Practical Guide to Algorithmic Strategies and Trading Systems, 2nd Edition

Since its inception in the early 1980s, high-frequency trading (HFT) has continued to evolve and grow. While some have tried to demonize it over the past few years, the fact is that HFT has delivered considerable operational improvements to the markets—most of which have resulted in lower volatility, higher market stability, better market transparency, and lower execution costs for traders and investors.

While "geeks" often claim HFT as their domain, anyone can integrate this proven approach into their trading endeavors. With minimal investment required, the barriers for entry into this field have never been lower, and the opportunity to generate significant profits has never been greater. Nobody understands this better than industry expert Irene Aldridge. And now, with the Second Edition of High-Frequency Trading, she returns to share her experience in this arena with you.

Building on the success of the first edition, this reliable resource incorporates the latest—yet applied and ready-to-implement—information on this essential trading approach. It also includes challenging end-of-chapter questions to test your command of the topics covered. Along the way, it:

  • Describes the technological evolution that has enabled algorithmic and HFT, and lays the foundation of analysis via descriptions of modern market microstructure, high-frequency data, and trading costs
  • Delves into the economics of HFT, exploring the methodologies for evaluating the performance and capacity of HFT strategies, and outlining the actual business of HFT
  • Addresses the actual implementation of HFT by detailing the core models of today's HFT strategies, from statistical arbitrage and directional event-based trading to automated market making and liquidity detection
  • Examines the real risks inherent in many HFT strategies and the ways to mitigate or minimize them
  • Discusses modern legislation relevant to HFT, traditional and current approaches, and likely imminent directions
