There was a time when humans were fascinated by computers, and now we have reached an era where advanced AI and technology can be used in nearly every aspect of life, including trading. With these technological advancements, traders can now leverage algorithmic trading, commonly known as algo trading, to potentially create a successful trading portfolio. Learn all about algorithmic trading, how it works, and its various applications in the trading world in this blog.
Algo trading, algorithm trading or algorithmic trading, uses computer programs and software to execute trading strategies automatically based on predefined rules and algorithms. Traders use algo trading to buy and sell stocks, futures, and other financial instruments efficiently and quickly by keying in specific parameters like price, quantity, and volume. These algorithms analyse market conditions to execute trades and manage portfolios without human intervention. This helps traders to take maximum advantage of market opportunities and reduce the impact of emotions on trading decisions.
Algorithm trading is a fascinating way to trade that leverages the power of technology to make intelligent, automated decisions. So now the question arises: How does algorithm trading work? It begins by designing a trading algorithm based on trading indicators and market data to spot trading opportunities.
This algorithm is then backtested with historical data to ensure it performs well under different market conditions. After reviewing the results and making necessary changes, the algorithm is deployed on a trading platform where it continuously monitors the market and executes trades at lightning speed, which is beyond the capacity of an average human.
Algo trading is also equipped with effective risk management techniques such as stop-loss orders and position size limits to protect against significant losses, ensure trading stays within set parameters, and align with the trading plan.
Now that we have seen the details of algorithmic trading, let us consider the following example to understand the concept better.
Consider Trader A, who has an algo trading program that follows a momentum strategy. The program focuses on the auto sector and has identified a stock, ABC Ltd., that has been consistently rising in price over the past few days.
The algorithm is keyed to buy 100 shares of ABC Ltd. at its current price of Rs. 100 per share as it sees a strong upward momentum. The total investment for buying 100 shares would be Rs. 10,000 (100 shares x Rs. 100 per share). The profit target is set at 10% and stop-loss at 5%. This means the program will sell the shares automatically if they reach Rs. 110 (10% profit) or drop to Rs. 95 (5% loss).
The algorithm will then continuously monitor ABC Ltd's stock price. If the price reaches Rs. 110 per share, the program automatically sells all 100 shares, resulting in a profit of Rs. 1,000 (10% of Rs. 10,000). If the price drops to Rs. 95 per share, the program sells all 100 shares to limit losses to Rs. 500 (5% of Rs. 10,000).
This automation helps traders to make timely decisions and manage their portfolios efficiently as well as take advantage of real-time market movements at a rapid pace.
Various categories of algorithms are used in financial markets to execute trades automatically. These algorithms are designed to follow specific rules and strategies to make trading decisions without human intervention. Popular types of algorithmic trading include,
Execution algorithms are designed to buy or sell orders at the most favourable prices, focusing on reducing the market impact of large trades. These algorithms ensure that orders are executed smoothly and efficiently, optimising transaction costs and minimising the price changes that large orders might cause.
VWAP algorithms execute trades based on the volume of assets traded over a specified period. They aim to achieve average prices relative to trading volume, reducing market impact and ensuring that orders are executed at fair prices consistent with market activity.
HFT algorithms execute a vast number of orders at extremely high speeds. They exploit minor price discrepancies in the market, often holding positions for very short durations. The goal is to generate profits from rapid trading and small price changes that occur in fractions of a second.
Statistical arbitrage algorithms use statistical and mathematical models to identify and exploit market inefficiencies. They analyse the historical price relationships between different securities and execute trades, assuming that these relationships will revert to their historical norms after profiting from temporary deviations.
Market-making algorithms aim to provide liquidity by continuously quoting buy and sell prices for a specific security. They profit from the bid-ask spread and typically operate in high-frequency trading environments. This ensures continuous market participation and facilitates smoother market operations.
The increased interest in trading coupled with access to advanced trading platforms has increased the scope and users of algo trading over the years. Aglo trading is rapidly shaping the trading portfolio for traders who are increasingly dependent on this form of trading to execute trades successfully. A few advantages of algorithmic trading are highlighted here.
Speed and Efficiency - Algo Trading executes trades swiftly, capturing fleeting market opportunities and optimising trade execution for better prices.
Cost efficiency - Algo trading minimises operational costs and transaction expenses by automating trade execution and reducing manual intervention.
Low latency - Algo trading is operated at lightning speed, thereby capitalising on market opportunities in real-time and reducing order execution times.
Eliminating human error - It eliminates emotional biases and human errors, ensuring trades are executed based on predefined rules and strategies.
Consistency and improved accuracy - Algorithm trading is based on consistent and predefined rules, which leads to improved accuracy and disciplined trading behaviour among traders.
Backtesting and optimisation - Algo traders can backtest their strategies using historical data and optimising them for better performance before deploying them in live markets.
While algo trading is here to stay, there are a few limitations that traders need to watch out for before taking the plunge into algo trading. Here are some of the disadvantages of algorithm trading.
Technical challenges - Algorithmic trading can face technical challenges like connectivity issues or software bugs, potentially leading to losses if not managed well. Traders should also be cautious about over-reliance on these systems and trading platforms as it may lead to neglecting manual oversight and risk management and exposing them to vulnerabilities like unexpected events or technical failures.
Dependence on historical data - Algo trading relies heavily on historical data for backtesting and developing trading strategies. However, market conditions can change and therefore, relying solely on past data may not always lead to optimal results in dynamic markets.
Risk of overfitting - Overfitting occurs when algorithms are overly tuned to historical data, leading to suboptimal performance in live markets. Traders must strike a balance between backtesting and real-world adaptability to avoid overfitting.
Lack of human judgment - Algorithms lack human judgment and intuition, which can be crucial in certain market conditions or unforeseen events. Traders must supplement algorithmic strategies with human oversight and decision-making to mitigate potential risks.
Regulatory risks - Algo trading is subject to regulatory scrutiny, and changes in regulations or compliance requirements can impact trading strategies and operations. Traders must stay updated with regulatory developments and ensure their algorithms comply with legal standards.
Algorithmic trading strategies are automated trading approaches that use computer programs to execute trades based on predefined rules and criteria. Some of the popular algorithmic trading strategies are,
This is one of the simplest algo trading strategies and involves buying or selling assets that are already showing strong price movements. The purpose of this strategy is to ride the current momentum and make profits from continued price increases or decreases in the short term.
Trend-following strategies focus on identifying and trading in the direction of prevailing market trends. Traders using this strategy analyse price charts and technical indicators to determine the trend's direction, such as uptrends or downtrends. The goal is to ride the trend until signs of a reversal appear, capturing profits along the way.
Arbitrage trading exploits price discrepancies for the same asset across different markets or exchanges. Traders simultaneously buy and sell the asset in different markets to profit from the price difference. This strategy requires quick execution and sophisticated technology to capitalise on fleeting opportunities.
Scalping is a popular algo trading strategy in which traders aim to profit from minute profits backed by frequent trades. The aim is to capitalise on small price movements and execute trades with precision and efficiency to accumulate significant profits throughout the day.
Breakout trading involves identifying key levels of support or resistance on price charts. Traders wait for the price to break through these levels, which signals a potential shift in market sentiment. They then enter trades in the direction of the breakout, anticipating a significant price movement and aiming to capture profits from the resultant volatility.
Index fund rebalancing is a strategy to maintain an index fund's composition in line with its benchmark index. This algo trading strategy rebalances the portfolio periodically by buying or selling assets to align with changes in the index's composition or weightage. This strategy aims to track the index's performance closely and optimise returns for investors in the index fund.
Algorithmic trading uses an automated and rule-based approach, which has become a cornerstone of modern trading practices. It helps traders capitalise on market opportunities by executing trades based on predefined criteria and optimising entry and exit levels for better risk management and profitability. However, it is crucial to understand the limitations of algo trading to safeguard the portfolio from the risks of the same.
Yes, algorithmic trading is legal for traders in India and is regulated by the SEBI. Therefore, traders must comply with all the SEBI guidelines and regulations when using algorithmic trading to shape their trading portfolios.
Traders can start algorithmic trading by learning programming languages like Python, Java and C++, familiarising themselves with trading platforms that support algorithmic trading, and staying updated with SEBI's guidelines on algorithmic trading. You could use Fyers’ API to start algo trading or use it to integrate third-party platforms for algo trading.
Algorithmic trading can be effective for traders when implemented correctly with robust algo trading strategies and risk management techniques. However, success is not guaranteed as it depends on factors like market conditions, the quality of algorithms used, and the trader's understanding of financial markets.
