RT Journal Article SR Electronic T1 COMMENTARY: A Retrospective Look: Phantom Liquidity and High-Frequency Quoting JF The Journal of Trading FD Institutional Investor Journals SP 117 OP 118 DO 10.3905/jot.2018.13.4.117 VO 13 IS 4 A1 Jesse Blocher A1 Rick Cooper A1 Jonathan Seddon A1 Ben Van Vliet YR 2018 UL https://pm-research.com/content/13/4/117.abstract AB In this paper we take a retrospective look at our paper “Phantom Liquidity and High-Frequency Quoting” and discuss the context of the research in light of our broader inquiry into the nature of the high-frequency trading industry. 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
