The data presented in this paper appear to show that limit order cancellations of high-frequency traders are associated with price discovery and liquidity provision, rather than some manner of systematic taking advantage of other market participants. These firms are acting as rational, profit-seeking businesses, and we believe time has shown this view to be correct. In the years since publication, HFT has matured, and consolidated into fewer, lower-cost providers of efficiency and liquidity services, much like we would expect in any other industry.TOPICS: Legal/regulatory/public policy, quantitative methods ER -
