RT Journal Article SR Electronic T1 Phantom Liquidity and High-Frequency Quoting JF The Journal of Trading FD Institutional Investor Journals SP 6 OP 15 DO 10.3905/jot.2016.11.3.006 VO 11 IS 3 A1 Jesse Blocher A1 Rick Cooper A1 Jonathan Seddon A1 Ben Van Vliet YR 2016 UL https://pm-research.com/content/11/3/6.abstract AB This article examines every NASDAQ ITCH feed message for S&P 500 Index stocks for 2012 and identifies clusters of extremely high and extremely low limit-order cancellation activity. The authors find results consistent with the idea that cancel clusters are the result of high-frequency traders jockeying for queue position and reacting to information to establish a new price level. Furthermore, few trades seem to be executed during cancel clusters or even immediately after them. Low cancellation activity seems to be markedly different, with many level changes all caused by executions. The results are consistent with high-frequency trading firms behaving as agents who bring efficiency to the market without the need to have executions at intermediate prices. The authors also discuss the misconception that investors and low-frequency traders are synonymous and its implications for policy given these results.TOPICS: Legal/regulatory/public policy, quantitative methods
