The use of technology in stock markets has revolutionised the access and the mode of investing and trading for an average Indian. This also prompted the use of technology for the execution of rapid trades in high frequency that can be instrumental in building a successful portfolio. So what is the meaning of high-frequency trading and how to build a portfolio using it? Given here are the details of the same.

High-Frequency Trading (HFT) refers to a type of trading strategy that uses advanced computer algorithms to execute a large number of trades at incredibly fast speeds. In simple words, it’s like super-fast trading done by computers. HFT relies on powerful computers and sophisticated software programs to analyze market data, identify patterns, and execute trades within fractions of a second. These trades can involve buying or selling stocks, commodities, currencies, or other financial instruments.
The goal of HFT is to take advantage of small price differences that occur in the markets within very short time periods. Computer algorithms can react swiftly to changing market conditions and execute trades faster than human traders can. HFT has become popular because it can generate profits from these tiny price differences when executed at high volumes and frequencies. However, it’s important to note that HFT requires substantial investments in technology and infrastructure to compete in the high-speed trading environment.
HFT operates in highly competitive environments, where milliseconds matter. To be successful, HFT firms invest heavily in high-speed data connections, co-located servers near exchanges, and advanced trading technologies to minimize latency. Technology is used to identify trading opportunities and execute the same in a fraction of a second. The process can be explained as under.
There are several trading strategies that are adopted under high-frequency trading. Some of the common strategies are highlighted below.
In market making, HFT firms play the role of intermediaries by constantly providing liquidity to the market. They place both buy and sell orders for various securities, such as stocks or currencies, with the intention of profiting from the bid-ask spread. The bid price represents the highest price a buyer is willing to pay, while the ask price is the lowest price a seller is willing to accept. By placing orders close to the current bid and ask prices, HFT firms facilitate trading and help ensure there is always a market available for buyers and sellers.
Statistical arbitrage is a strategy employed in high-frequency trading to identify price differences among different securities traded on various exchanges or markets. This approach involves analyzing historical and real-time market data to detect instances where the prices of related securities deviate from their usual patterns. High-frequency traders using statistical arbitrage focus on liquid securities like bonds, equities, currencies, and futures. This strategy may also incorporate traditional arbitrage techniques, such as interest rate parity, to exploit pricing discrepancies and generate profits.
News-based trading strategies focus on reacting to news events that can impact financial markets. HFT algorithms process vast amounts of news data, including earnings releases, economic indicators, and geopolitical developments. By analyzing the news and its potential impact on prices, the algorithms aim to execute trades swiftly to capitalize on the expected market movements triggered by the news event. The speed of HFT allows for rapid response, often even before human traders can fully digest the news.
Scalping is a strategy where HFT firms aim to profit from small price discrepancies in the market. The algorithms quickly enter and exit trades, taking advantage of these small price differences, often capturing just a fraction of a cent per trade. While the profit per trade may be small, the high frequency at which these trades are executed can result in significant cumulative profits.
The benefits and shortcomings of high-frequency trading are highlighted below.
The advantages or merits of high-frequency trading include,
HFT firms actively participate in the market as market makers, providing liquidity by continuously placing buy and sell orders. This helps ensure that there is a ready market for buyers and sellers, enhancing overall market liquidity.
The constant presence of HFT firms in the market helps to narrow the bid-ask spread—the difference between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept. This can benefit traders by reducing transaction costs.
HFT’s rapid analysis and execution capabilities contribute to efficient price discovery. By processing vast amounts of market data and reacting swiftly to news and events, HFT algorithms help prices reflect relevant information accurately and in a timely manner.
High-frequency trading is often considered more efficient than traditional trading because it eliminates human interference. In contrast, high-frequency trading relies on computer algorithms that can execute a large volume of orders at incredibly fast speeds. The automated nature of high-frequency trading enables swift decision-making and eliminates human errors that can occur during manual trading.
The shortcomings of high-frequency trading are mentioned below.
HFT’s speed and automated nature can amplify market volatility. Algorithms reacting to market movements and engaging in rapid trading can contribute to sudden and sharp price fluctuations, potentially leading to increased market instability.
HFT’s complex nature poses challenges for regulators in terms of monitoring and oversight. Regulating HFT practices and addressing potential market abuses, such as front-running or market manipulation, requires continuous adaptation to keep pace with evolving technology and trading strategies.
HFT requires substantial investments in advanced technology and infrastructure. This can create a disparity in market access, as only firms with significant financial resources can compete in the high-speed trading environment. Smaller investors may feel disadvantaged due to limited access to the same level of technology and market data.
High-frequency trading (HFT) is a sophisticated and costly trading approach that utilizes advanced tools and software. It operates within a narrow window of opportunity, executing rapid buy and sell transactions across multiple markets in a very short duration. Traders who engage in HFT need to thoroughly understand the intricacies of this specialized trading system and carefully assess all aspects before proceeding with their investments.
HFT is predominantly employed by major hedge funds, independent proprietary trading units, and brokerages.
High-frequency trading is regulated by SEBI in India and all the participants have to adhere to the rules and regulations set up by SEBI in this regard.
High-Frequency Trading (HFT) and algorithmic trading (algo trading) are related concepts, but there are some distinctions between the two. HFT is a specific type of algorithmic trading that focuses on executing high-speed trades to exploit short-lived market opportunities. Algo trading is a broader term encompassing a wide range of trading strategies executed using computer algorithms, including both high-frequency and other types of automated trading.
Despite being a relatively new market in India, High-Frequency Trading has attracted significant attention and understanding among traders. It has emerged as a highly profitable venture, with several start-ups exclusively focusing on this trading strategy. The number of such start-ups is expected to grow in the future.
