This practice is now poised to dominate the regular volume of order flow. More seriously, it brings into perspective issues such as induced excess volatility, whether the playing field is level for all market participants, and even the informational efficiency of security markets. In this article, the authors review what high-frequency trading is, and explore the links between such trading and market efficiency and volatility. Finally, they assess the potential for further trading practices to emerge, the likes of which most observers would not have imagined as feasible even 10 years ago.TOPICS: Big data/machine learning, exchanges/markets/clearinghouses
