Focussing on the Negative Aspects of HFT
In our previous report High Frequency Trading – The Good, The Bad, and The Regulation, we identified and grouped a variety of High Frequency Trading strategies. We concluded that classifying all HFT as “bad” was too broad a generalisation, as we found evidence of strategies that improved market quality alongside those that did not.
We think it is important to highlight liquidity-enhancing strategies such as market making or statistical arbitrage, which seek to correct short term mispricing. However, this report will focus specifically on strategies which seek to create short term mispricing, and how to respond accordingly to this “bad” HFT.
Concrete Examples and Detection Techniques
In this piece we highlight a subset of negative high frequency trading, examining strategies such as: Quote Stuffing, Layering/Order Book Fade and Momentum Ignition. We analyse a number of different aspects of these strategies, providing examples to help demonstrate what they “look” like, as well as broader data statistics on how often they occur and how we detect them.
Exhibits 1 and 2 below provide examples of Quote Stuffing, which is one of the most visually obvious forms of HFT. We will delve into Quote Stuffing in more detail in the next section. We then focus our analysis on Layering/Order Book Fade and Momentum Ignition in subsequent sections. Finally, we highlight the ways in which AES responds to “bad” HFT, protecting our clients and enhancing our strategies.High Frequency Trading, Algorithmic Buy-Side Execution and Linguistic Syntax : high_frequency_trading_algorithmic_buy-side_execution_and_linguistic_syntax.pdf

1) When does the authorisation requirement for highfrequency trading as defined in the High-frequency Trading Act (hereinafter High-frequency Trading) take effect?
The High-frequency Trading Act entered into effect on 15 May 2013. However, with respect to the authorisation requirement, the Act stipulates transitional periods for applying for an authorisation (see section 64p of the Banking Act (Kreditwesengesetz – KWG). A transitional period of six months, i.e. until 14 November 2013, for submitting an application for authorisation is stipulated. For enterprises that are not domiciled in Germany and that are not enterprises within the meaning of section 53b (1) sentences 1 and 2 of the KWG, a transitional period of nine months until 14 February 2014 is stipulatedTapping the Brakes: Are Less Active Markets Safer and Better for the Economy? tapping_the_brakes_-_are_less_active_markets_safer_and_better_for_the_economy.pdf
But often, those changes in sentiments are related to perceptions, to beliefs, which can spread across the investment community, with little relationship to underlying fundamentals. Rob Shiller and others have documented that much of the variation in stock market prices cannot be explained by changes in fundamentals, or news about changes in fundamentals2. There was nothing so dramatic unveiled in October 1987 that could come any way near accounting for the wiping out of a quarter of the value of the stock market. There were no changes in the fundamentals that could account for the wiping out of a trillion dollars of stock market value in the flash crash of May, 2010.
Keynes talked about these changes in sentiments in terms of animal spirits. Using a context that today would be viewed as politically incorrect, he focused on the market as a beauty contest, where the objective was not to ascertain the “fundamentals,” but rather to assess what others were thinking. Modern research in psychology, sociology, and social psychology has begun to explore how each of our beliefs are shaped by those around us; there can be contagion—spirits of optimism and pessimism can spread. (There can also be rational expectations contagion—actions of individuals can convey information; but the observed patterns entail more than this.)The Anatomy of a High-Frequency Trader: Human and Machine Proportions : the_anatomy_of_a_high-frequency_trader_-_human_and_machine_proportions.pdf
