Interview with a High-Frequency Trading Expert : interview_with_a_high-frequency_trading_expert.pdf
There are two very different answers to that question. Supporters claim that high-frequency traders (HFTs) are a net-positive market force because they provide liquidity and tighten bid-ask spreads. They say that high-frequency trading is rarely if ever used for nefarious purposes, and regulators make sure of it.
On the other side, detractors claim that HFTs regularly manipulate unaware investors and otherwise destabilize markets. They say that HFTs are a net-negative force on the market and should be reined in.
The answer surely lies somewhere in between. But which is closer to the truth? To find out, we talked to Garrett, an expert on market systems and high-frequency trading. Having experienced first-hand the problems HFTs can cause, he fits firmly in the “detractor” camp, for reasons you’ll read below. Garrett gave us excellent insight into how HFTs profit, along with tips on how to make sure they don’t profit at your expense.
I found this interview highly educational, and I hope you do too. It contains the kind of inside intelligence that separates the informed from the uninformed and allows us as individual investors to understand and adapt to our changing markets.What’s Next for High Frequency Trading? whats_next_for_high_frequency_trading.pdf
Co-Evolving Online High-Frequency Trading Strategies Using Grammatical Evolution : co-evolving_online_high-frequency_trading_strategies_using_grammatical_evolution.pdf
When developing trading models, it is necessary to consider both entry- and exit strategies. The entry strategy decides when to enter a bid or offer into the market (or when to remain idle), whereas the exit strategy decides when to cut losses short or when to take profit by closing open positions in the market. Furthermore, a highly desirable property of any trading model is a high return-to-risk ratio with a low trading cost. Therefore, a trading model needs to consistently produce positive returns whilst minimizing risk and trading costs.
The most lucrative form of trading is high-frequency trading, i.e. when trading decisions are made intra-day, usually using a minute-, second- or millisecond time resolution. In a high-frequency setting, the availability of timely, fundamental economic and financial information is scarce, hence technical indicators are employed in this study.The Trading Profits of High Frequency Traders : the_trading_profits_of_high_frequency_traders.pdf
In this paper, we study market efficiency by focusing on a particular type of investor, High Frequency Traders (HFTs). HFTs depend on speed, which is closely related to information – it is the ability to react to and incorporate information into market prices. Whether it is using expedited information to make an investment, reduce risk, or mitigate the costs of adverse selection, those quickest to react can capture informational rents.
We document that HFTs generate consistent and large excess returns in one of the most liquid and competitive financial markets - the E-mini S&P 500 futures market. These excess returns likely arise as a result of exploiting fleeting informational advantages at short time scales. We find that while HFTs bear some risk, they generate an unusually high average Sharpe ratio of 9.2. The concentration of profits among these few rapidly trading market participants - 31 out of over 31,403 traders – reveals deviations from market efficiency at very short intervals. Within these 31 firms, a small group of aggressive (liquidity-taking) HFTs are the most profitable.high-frequency_trading_and_execution_costs.pdf

For high frequency trading (HFT) response times have gone from milliseconds to microseconds. In such an environment, even fiber optic connections can be too slow. Microwave connections, with latency measured in nanoseconds, can provide the necessary speed.
The New Market Maker HFT grew out of the SEC’s 1998 decision to allow electronic exchanges to compete with the NYSE and other marketplaces. By 2010, HFT was accounting for more than 70% of the trades in U.S. equity markets, and a growing percentage of trades in other countries.advances_in_high_frequency_strategies.pdf
•Predatory algorithms are a special kind of informed traders. Rather than possessing exogenous information yet to be incorporated in the market price, they know that their endogenous actions are likely to trigger a microstructure mechanism, with foreseeable outcome.Examples include:
–Quote stuffing: Overwhelming an exchange with messages, with the sole intention of slowing down competing algorithms.
–Quote dangling: Sending quotes that force a squeezed trader to chase a price against her interests.
–Pack hunting: Predators hunting independently become aware of each others activities, and form a pack in order to maximize the chances of triggering a cascading effect.optimal_strategies_of_high_frequency_traders.pdf

as the National Association for Securities Dealers Automated Quote (NASDAQ) market and the New York Stock Exchange (NYSE), have maintained relevance and centrality in financial intermediation in financial markets settings that have changed so much in the past 20 years that they are hardly recognizable. In this article, we explore the technological, institutional and market developments in leading financial markets around the world that have embraced HFT trading. From these examples, we will distill a number of common characteristics that seem to be in operation, and then assess the
extent to which HFT practices have begun to be observed in Asian regional financial markets, and what will be their likely impacts. We also discuss a number of theoretical and empirical research directions of interest.optimal_strategies_of_high_frequency_traders_1.pdf
