Summary

High-frequency trading (HFT) is a specialized form of algorithmic trading characterized by ultra-high speeds, high turnover rates, and high order-to-trade ratios. Utilizing sophisticated algorithms and co-location, HFT firms execute millions of trades daily with investment horizons lasting only fractions of a second. While HFT provides market liquidity and narrows bid-ask spreads, it is also associated with increased volatility and events like the 2010 Flash Crash. Notable figures like Changpeng Zhao began their careers developing HFT order execution systems for firms in Tokyo and New York, and major firms like Virtu Financial and Tower Research Capital dominate the space. Regulatory scrutiny remains high, with several European countries proposing restrictions to mitigate market instability.

High-frequency trading

High-frequency trading (HFT) is a type of algorithmic automated trading system in finance characterized by high speeds, high turnover rates, and high order-to-trade ratios that leverages high-frequency financial data and electronic trading tools. While there is no single definition of HFT, among its key attributes are highly sophisticated algorithms, co-location, and very short-term investment horizons in trading securities. HFT uses proprietary trading strategies carried out by computers to move in and out of positions in seconds or fractions of a second. In 2016, HFT on average initiated 10–40% of trading volume in equities, and 10–15% of volume in foreign exchange and commodities. High-frequency traders move in and out of short-term positions at high volumes and high speeds aiming to capture sometimes a fraction of a cent in profit on every trade. HFT firms do not consume significant amounts of capital, accumulate positions or hold their portfolios overnight. As a result, HFT has a potential Sharpe ratio (a measure of reward to risk) tens of times higher than traditional buy-and-hold strategies. High-frequency traders typically compete against other HFTs, rather than long-term investors. HFT firms make up the low margins with incredibly high volumes of trades, frequently numbering in the millions. A substantial body of research argues that HFT and electronic trading pose new types of challenges to the financial system. Algorithmic and high-frequency traders were both found to have contributed to volatility in the Flash Crash of May 6, 2010, when high-frequency liquidity providers rapidly withdrew from the market. Several European countries have proposed curtailing or banning HFT due to concerns about volatility. Other complaints against HFT include the argument that some HFT firms scrape profits from investors when index funds rebalance their portfolios.

    Thanks to new microchips, orders can now be submitted within 740 billionth of a second (O'Hara, 2015). U.S. equities exchange, CBOE BYX, reduced order processing times to 64 microseconds in 2018 (Baldauf & Mollner, 2020). High-frequency trading (HFT) is an algorithmic trading (AT) type, which involves heavy order submission within latencies as low as nanoseconds. As of 2008 and 2009, HFT accounted for 42% of trading volume in the large cap stocks listed in NASDAQ and NYSE (Brogaard, Hendershott, & Riordan, 2014). By then, 26 HFT firms participated in 73.8% of all trades in the US equity market (Brogaard, 2010). Hagströmer and Norden (2013) report 25% to 50% HFT participation in the trading activity of 30 most traded stocks in Sweden. Based on the rest of the literature, Menkveld (2014) [...] The increasing volume of messages sent to the exchange by algorithmic traders stimulates a fierce debate among academics and practitioners on the impacts of high-frequency trading (HFT) on capital markets. By comparing a variety of regression models that associate various measures of market liquidity with measures of high-frequency activity on the same dataset, we find that for some models the increase in high-frequency activity improves market liquidity, but for others, we get the opposite effect. We indicate that this ambiguity does not depend only on the stock market or the data period, but also on the used HFT measure: the increase of high-frequency orders leads to lower market liquidity whereas the increase in high-frequency trades improves liquidity. We hypothesize that the [...] This study aims to develop a probabilistic model using machine learning techniques to identify high-frequency trading (HFT) based on order book data. The model enables precise intraday identifications, addressing the lack of a widely accepted framework for HFT identification and the inconsistencies arising from proxy indicators. Leveraging academic data, the model offers improved consistency and reproducibility for future HFT research. By incorporating fuzzy logic, the probabilistic model allows policymakers greater flexibility in shaping policies. The study utilises data from the BEDOFIH database of the French capital market and develops a robust classification model capable of accurately distinguishing HFT. Additionally, reverse engineering enhances the model’s interpretability by

  • High-Frequency Trading Explained: What Is It and How Do You Get ...

    ## What Is High-Frequency Trading? High-frequency trading is a type of automated trading that uses powerful computers to buy and sell financial assets incredibly quickly. The term “high frequency” refers to how quickly these trades are completed. They may take place in minutes, seconds or even milliseconds. One of the core principles of high-frequency trading is to generate small profits on a very large number of trades. Unlike long-term investing, which aims to make substantial returns on a few carefully selected assets, HFT strategies focus on capturing minuscule price differences on thousands or even millions of trades per day. While the profit from each individual trade is minimal, the sheer volume and speed at which they are executed can add up to substantial overall gains. [...] To achieve this, HFT firms rely on highly automated systems that integrate global market data, trading algorithms and ultra-low-latency infrastructure. Together, these systems continuously monitor multiple trading ecosystems, analyze price movements and place orders in real time. This level of automation allows high-frequency traders to process vast amounts of data and identify fleeting opportunities that humans would never notice on their own. For example, a price difference of just a fraction of a cent might exist between the same asset on two different exchanges. HFT algorithms can detect that discrepancy instantly — buying low on one exchange and selling high on another — thus capturing a small profit on each transaction. Repeated at a high volume and speed, these tiny margins add up [...] Can't find your company? Create a company profile.
