What Are The Risks of Algo Trading?

Algo trading has become a popular alternative to traditional trading, which can often be time-consuming and emotionally draining. Traders can now automatically execute trades at lightning speed using computer algorithms. While it offers many advantages—speed, precision, and efficiency—algo trading comes with its own set of risks. It’s crucial to understand these risks before diving into this high-tech approach to trading.

In this article, we explore some of the key risks involved in algo trading and ways to minimise
them.

Let’s Understand Algo Trading!

Algorithmic (algo) trading involves using automated, pre-programmed instructions to place orders in financial markets— stocks, derivatives (F&O), currencies, and commodities. These algorithms follow specific rules based on factors like price, timing, and quantity to identify trading opportunities and automatically execute orders once set conditions are met. Algos can analyse vast amounts of market data, monitor performance, and execute trades seamlessly, all without human intervention!

For instance, imagine a trader with a strategy to buy a stock when its price rises above the 50-day moving average and sell when it drops below. An algorithm can track this stock continuously and execute trades the moment the criteria are met. It’s rapid and reduces the time and effort required to trade, compared to traditional methods. This precision and efficiency make algo trading appealing for those who value speed and wish to minimise emotional biases in their trading decisions.

What are the Risks of Algo Trading?

1. Technical Glitches

Algo trading is highly dependent on technology, meaning any technical glitch can have serious consequences. A minor error, like a coding bug or server malfunction, can trigger unintended trades or even cause a series of rapid trades that disrupt the market. Such errors have, in extreme cases, led to flash crashes—sudden, severe market drops driven by automated trading gone wrong.

For instance, if a server outage stops the algorithm from executing trades, it could miss critical opportunities or fail to exit a position at the right time. To prevent this, traders should implement robust monitoring and backup systems. Having manual oversight and setting up contingency plans, like alert systems or manual intervention protocols, can help address issues as soon as they arise, reducing the impact of technical mishaps.

2. Data Quality and Integrity

The success of algo trading largely relies on the quality of data fed into the algorithm. Poor or outdated data can lead to inaccurate decisions, resulting in losses. For example, if an algorithm is backtested using unreliable historical data, it might suggest profitable patterns that don’t hold up in live trading. Real-time data errors, like incorrect prices, can also cause the algorithm to execute faulty trades.

To avoid this, traders should source data from reputable data providers/vendors and consistently verify its accuracy and integrity. [You can source data directly through exchanges, brokers, or data vendors.] Popular data vendors in India include TrueData, Global Datafeeds, and Accelpix.] Regularly updating data feeds and cross-checking sources can ensure the algorithm is always working with accurate information, minimising the risk of errors based on faulty data.

3. Overfitting

Overfitting occurs when an algorithm is overly customised to historical data, making it less effective in real-world trading. In essence, the algorithm “learns” past trends too well, which might limit its adaptability to current and future market conditions. For example, an algorithm might show great performance when tested on past data but struggle to generate profits when market conditions change.

One way to address overfitting is by designing algorithms that balance specificity with adaptability. Regularly testing the algorithm with new and varied data can also reveal whether it’s overly dependent on past trends. By developing flexible strategies, traders can ensure that their algorithms are capable of adapting to changing market dynamic

4. Cyber Threats

In today’s digital age, cybersecurity is crucial, especially for algo trading platforms where valuable trading strategies and sensitive data are stored. Hackers or cyber attackers might attempt to steal proprietary trading algorithms or disrupt trading activities. For instance, a hacker gaining access to a trading account could lead to unauthorised trades, resulting in significant financial losses.

Traders can mitigate this risk by investing in strong cybersecurity measures, such as multi-factor authentication and encrypted data storage. Regularly updating software and staying informed about the latest cybersecurity threats are essential practices. Ultimately, protecting trading systems against cyber threats is as important as developing profitable trading strategies.

5. Lack of Human Oversight

You may be wondering: isn’t algo trading all about eliminating manual aspects of trading? Well, there’s more to it. One critical risk in algo trading is the absence of human supervision, which can lead to unexpected and sometimes severe consequences. Algorithms are typically designed based on historical data and specific rules, meaning they may fail to account for rare or unforeseen market events, known as black swan events. For example, during a sudden market crash or an unexpected geopolitical event, an algorithm might continue trading in ways that amplify losses, as it lacks the judgment to pause or reassess in extreme conditions.

To mitigate this risk, it’s essential to maintain some level of human oversight. Regularly monitoring the performance of algorithms and having manual override options in place can help traders intervene when markets behave unpredictably. Staying informed about major events and adjusting algorithms accordingly can also reduce the chances of undesirable outcomes.

Conclusion

Here’s an important aspect we would like to mention: risks in algo trading can be highly subjective. What might be a significant risk for one trader could be manageable for another, depending on factors like their experience, financial capacity, and trading objectives. An experienced trader with a strong understanding of the market and ample capital might be more willing to take on risks compared to a beginner with limited resources.

The key to successful algo trading is not just recognising the risks but also knowing how to manage and mitigate them effectively. By implementing strong risk management practices, staying informed, and approaching each risk with a clear strategy, traders can navigate the challenges of algo trading more confidently.

Remember, no trading strategy is entirely risk-free, but with the right approach, you can maximise the potential rewards while minimising potential pitfalls in algo trading. 

FAQs

Common Mistakes to Avoid in Algo Trading in India

If you’re a trader navigating the complex financial markets, you must have heard about algo trading. It is the latest revolution where trades are executed with the help of computer “algorithms” or automated systems. If manual trading feels like a big hassle now due to your busy schedules, it’s time to consider algo trading! There are primarily two ways to participate in algo trading in India:

1. Complete DIY (do-it-yourself): In this approach, you need to create a trading strategy from scratch, code your algorithm (yes, it requires extensive technical knowledge), test it, and deploy it on your own.

2. Use dedicated platforms: Various algo trading platforms in India offer built-in strategies and tools to test & execute trades seamlessly.

But regardless of the methods you practice, errors are not just inevitable— they’re an essential part of the learning process. In this article, we will discuss various mistakes traders make while practising algo trading. We will also see how you can avoid those mistakes to have a more profitable trading journey. 

What Are The Common Mistakes Algo Traders Make?

If you choose the DIY approach, here are some common mistakes you could make while practising algo trading:

1. Poor backtesting

Backtesting is the process of testing the trading strategy/algorithm using historical data to predict its effectiveness in live markets. It’s like rewinding the clock and watching your strategy play out, trade by trade! 

Poor backtesting can mislead traders, causing them to overestimate a strategy’s real-world performance. Having limited historical data or ignoring noisy data (​​those containing errors, missing values, or irrelevant information) could lead to losses or sub-optimal results. Moreover, excessive testing or under-testing may also create problems during live trading. 

Traders often expect backtesting results to work out exactly as planned. However, such results often fail to capture the full complexity of live markets, including unexpected events, sudden shifts in liquidity, or changes in market sentiment.

To learn more about backtesting, please go through this article: Backtesting Algo Trading Strategies.

How to Avoid This?

  • Focus on the key principles of backtesting like defining objectives and choosing appropriate parameters & indicators. Ensure your historical data is accurate and complete (use reliable data sources from reputable providers).
  • Backtesting for longer periods (>3-5 years) helps build confidence that the strategy will perform well in various real-world market cycles.
  • Don’t use all your data for backtesting. Divide it into two sets: in-sample (for developing the strategy) and out-of-sample (for testing its performance on unseen data). This method will help you understand how well the strategy adapts to new market conditions.

2. Neglecting transaction costs and slippages

While backtesting, many traders forget to account for slippages or transaction costs like brokerage charges, taxes, and commissions. Traders need to incorporate these estimates into their models while backtesting. Neglecting this can lead to overestimating profits. Strategies can look extremely powerful and profitable on paper, but missing transaction fees can lead to reduced profits or even losses. 

[A “slippage” occurs when the price at which your order is executed does not match the price at which it was requested.]

How to Avoid This?

  • Include and modify the trading algorithm to incorporate these costs to ensure the results will give more realistic net profits. Estimate slippage based on historical data, trade size, etc.
  • Test with different cost conditions to figure out the perfect strategy. Look out for latency (delays) in order placement and execution!

3. Over-optimisation

Also known as curve fitting, this occurs when the algorithms are too excessively fine-tuned to historical data. The algorithm might fail to figure out new market conditions due to over-optimisation.

For example, consider an algo trader developing a moving average crossover strategy for the HDFC stock. Starting with a simple 50-day and 200-day moving average, he optimises his strategy extensively using 12 years of historical data (2010-2022). 

Then, he adjusts parameters, adds filters for volatility & volume, and eventually creates a complex strategy that uses 73-day and 187-day moving averages. This strategy promised an impressive 40% annual return in backtests. However, when deployed in 2023, it quickly lost 17% in the first three months, failing to adapt to new market conditions. This strategy fell victim to overfitting by being too precisely calibrated to past data, ignoring market noise, and becoming overly complex!

How to Avoid This?

  • Start with a basic strategy with limited parameters. Look for reasonable strategy performance with acceptable risk metrics. Only add new conditions or features if they deliver better results over time.
  • Use out-of-sampling testing and maintain cross-validation techniques.
    [Out-of-sample testing is a kind of testing you do on unknown data to know whether a backtested strategy is strong enough to work in a live market environment. Cross-validation is used to assess how well a trading strategy or algorithm will perform on new, unseen data.] 

4. Incomplete technological knowledge

Ignoring the technical aspects of algo trading can lead to errors, bugs, or faulty trade executions. Investors must have excellent coding skills (unless they use a third-party platform). Additionally, they need to be well-versed in data handling and all the software required for algo trading.

How to Avoid This?

  • Stay updated with all the latest technological advancements in the field of financial markets & algo trading. Practice coding and improve your skills regularly.
  • Look for alternate platforms where you can use their in-built strategies or strategy builder for creating and deploying. Eg: AlgoBulls.
  • Consult experts in the areas you lack and attend various lectures, talks and seminars on algo trading.

5. Insufficient risk management

Risk management plays a very crucial role in algo trading. Failing to set stop-loss parameters or having a faulty algorithm could even wipe out your entire trading capital. Concentrating risk in a single strategy, asset class, or market sector increases vulnerability to specific market events. Moreover, many traders fail to account for low-probability, high-impact events (black swans), which can lead to significant losses when these events occur.

How to Avoid This?

  • Use position-sizing (allocating a predetermined percentage of your capital to each trade), portfolio diversification, and set stop loss (SL) rules to reduce the potential risks and implement operational risk management strategies like recovery and backup systems, backup power sources, etc.
  • Make sure your algo trading strategies adapt to changing market conditions and economic events. Keep track of news and trends which can create market volatility.

6. Poor Trade Execution

We feel trade execution is the most important step in algo trading. A well-designed strategy can identify profitable opportunities. But if execution is poor, you might not capture those gains. For example, an algorithm aiming to buy at a specific price point might miss the opportunity entirely if execution is slow or inefficient.

How to Avoid This?

  • Invest in high-performance hardware and software, co-location services, and low-latency network solutions to improve the infrastructure.
  • Improve order execution by carefully selecting appropriate order types, and setting stop-loss orders and developing effective order routing algorithms. 

7. Lack of monitoring

A trader’s work is not completed after the algorithm is deployed, they can’t just relax. You could incur losses if you fail to keep track of your algorithm or conduct regular checks for glitches. Failing to monitor the trade performance and not optimising the technical indicator parameters/conditions could cause severe issues in the long run. Not having a backup plan or alerting systems can result in losses or low profits.

How to Avoid This?

  • Use real-time risk management in trading, implement monitoring tools and set up alerts to evaluate real-time performance.
  • Implement regular reviews, and performance assessments and make necessary timely changes to optimise the probability of making profits.

Mistakes to Avoid While Using Third-Party Platforms

One of the biggest mistakes algo traders make is falling victim to mis-selling. This mostly comes from the platforms that offer trading strategies or algorithms. In most cases, this comes as:

  • Inflated performance claims: Most of these platforms or vendors will exaggerate the historical return of their algorithms by presenting overly optimistic back-test results that do not include real-world factors.
  • Lack of transparency: Sellers rarely disclose the exact methodology of their algorithm, which might make it difficult for buyers to check and validate certain claims or even know the risks involved.
  • Not considering individual suitability: Most buyers never check whether the pre-made algorithm fits their risk tolerance, capital, or trading goals.
  • Underestimating challenges in implementation: Most traders underestimate the technical expertise required to properly implement and maintain the purchased algorithms.

Traders should properly research all algo trading platforms, demand complete documentation of their services & costs, and verify the performance claims independently.

Conclusion

In the world of algo trading, mistakes are inevitable and part of the learning process. However, true growth comes from recognising these errors and avoiding them in the future. The path to becoming a successful trader can be challenging, but with the right mindset and tools, you can confidently navigate the complexities of the market. We’ve highlighted several common mistakes traders often encounter and practical solutions to overcome them. Remember, knowledge is power, but the application of that knowledge leads to success!

Frequently Asked Questions (FAQs)

1. What is the biggest mistake beginners make in algo trading?

The most common mistake beginners make while starting algo trading is poor backtesting (testing the trading strategy/algorithm using historical data to predict its effectiveness in the live markets). Moreover, many traders either over-optimise their strategy based on past data (curve fitting) or forget real-world factors like transaction costs (brokerage) and slippages. This leads to unrealistic expectations or even losses in live trading.

2. How can I prevent over-optimisation (curve fitting) in my trading algorithm?

To avoid over-optimisation, start with a simple strategy using limited parameters (rules) and only add more rules if it improves performance consistently. Use out-of-sample testing and cross-validation techniques to ensure your strategy adapts to real market conditions rather than just historical data.

3. Why is it important to monitor your trading algorithm even after deploying it?

Algo trading isn’t a “set it and forget it” system. Markets change, errors can happen, and external factors can impact performance. Regular monitoring, alerts, and adjustments help keep your strategy profitable and running smoothly.

What is Algo Trading? History, Benefits Explained!

Algorithmic trading or algo trading has become a popular buzzword in the financial markets over the past few years. It has revolutionised the way people trade. The combination of financial knowledge and computer programs has resulted in faster and more accurate trade executions. In this article, we will help you understand what algo trading is and how it works. We will also discuss the advantages and risks of algo trading in India.

What is Algo Trading?

Algo trading is a method of executing orders in the financial markets (stocks, currencies, commodities, derivatives, etc.) using automated or pre-programmed trading instructions. The ‘algorithm’ places orders based on specific rules and criteria. These criteria include price, timing, and quantity instructions. The trading algorithm follows the instructions to identify opportunities in the market and executes orders when the conditions are satisfied.

Algo trading removes human emotions from the equation. Therefore, it helps avoid manual decision-making and human errors. 

What is an Algorithm?

An algorithm is a set of instructions/directions for solving a problem. It’s a step-by-step process that helps us solve problems or make decisions. These programs or algorithms operate faster than humans and make decisions at lightning-fast speeds. It is a seamless integration of technology and finance.

Brief History of Algo Trading

Algo trading has a rich history, dating back several decades. It gained significant momentum with advancements in technology, which allowed for faster and more complex algorithms.

It all started in the 1970s when computerised trading systems emerged in the American financial markets. In 1976, the New York Stock Exchange (NYSE) introduced an electronic trading system, which traders loved and accepted quickly.

An author named Michael Lewis played a significant role in popularising algorithmic trading. He brought it to the attention of both market traders and the public through his writings, especially when he talked about high-frequency algorithmic trading (HFT). In the US stock market and many other developed financial markets, about 60-75% of the overall trading volume is now generated through algo trading.

In 2008, algo trading got the green light from SEBI (India’s market regulator), and Direct Market Access (DMA) was introduced. DMA gives direct access to the electronic facilities and order books of the stock exchanges to execute trades. This opened the doors to high-frequency trading (HFT) in Indian stock exchanges, allowing more traders to participate actively in the market. But the real game-changer came in 2010 when large institutional brokers were permitted to co-locate their trading servers on the exchange premises. This tiny advantage of a millisecond gave them an edge over regular investors.

How Does Algo Trading Work?

Algo trading is a complex process that involves many steps and processes. However, a basic outline of how algo trading works is given below:

1. Developing a Strategy

The first step in algo trading is to develop a trading strategy. Traders can create and develop strategies based on technical, fundamental, and quantitative analysis. Moreover, in recent times, traders have been using Artificial Intelligence (AI) and Machine Learning (ML) for sentimental and qualitative analysis. Historical patterns, indicator signals, price behaviour, etc., are also analysed to create strategies. 

2. Writing the Algorithm

Once the strategy is developed, the next step is to convert it into a form that computers understand. Data scientists or traders write algorithms or codes that translate the strategy. Programming languages such as Python, C++, and Java are used to write algorithms for algo trading.

3. Backtesting

Before deploying an algorithm in live markets, traders backtest it on historical data. This means that the trading strategy gets simulated or replicated in the past market. Backtesting is necessary to understand its performance in the past. This step is based on the technical analysis principle that “history tends to repeat itself”. 

However, past performance is never a guarantee of future performance. The backtesting provides different metrics such as the total return, average monthly return, standard deviation of returns, etc. [Here, deviation is nothing but a difference in the actual returns and the expected returns.] Traders make multiple optimisations and revisions before deploying the strategy in live markets.

4. Connectivity

An Application Programming Interface (API) establishes an online connection between a data provider and an end user. An API connects the algo trading system to a trading platform/broker. It is essential to implement an automated trading strategy. APIs enable real-time market data access and trade execution.

5. Order Execution & Risk Management

Once the algorithm is set, it’s time to wait. Algorithms continuously analyse market data according to the strategy. When the conditions in the strategy are satisfied, the system automatically executes buy or sell orders. Moreover, the algorithms also place stop-loss orders and perform position sizing based on the strategy to manage risk. 

6. Monitoring and Forward Testing

Before the final deployment, the strategy needs to be forward-tested. Forward testing is a method of evaluating the performance of a trading strategy by applying it to real-time market data. Forward testing ensures that the algorithm works as intended. It helps to understand how our system performs in real-time, on data that the strategy has never seen before. Any deviations or unexpected variations are corrected and optimised further.

7. Final Deployment

After forward testing the strategy, the final step is to deploy the strategy. In forward testing, the account will not be fully funded. Here, the account is fully funded and deployed in real markets. Additionally, the trades and strategies get monitored and revised periodically.

Basic Types of Algo Trading

  • High-Frequency Trading (HFT) – High-frequency trading (HFT) is a type of super-fast trading done by powerful computers. These computers use smart algorithms to quickly buy and sell stocks and other assets in different markets. Since they’re so fast, HFT computers can make lots of trades in just a short time. Traders who use HFT aim to make profits by taking advantage of small price changes.
  • Arbitrage Trading – Arbitrage refers to the practice of taking advantage of price differences for the same asset in different markets. This type of algo trading involves using automated computer programs to identify and exploit these price differences quickly and efficiently. To learn more about arbitrage trading, click here!

What are the Advantages of Algo Trading?

1. Speed and Efficiency

Algo trading operates at lightning-fast speeds. The computer program executes all the trades in mere seconds, enabling timely responses to market changes without delay. On the other hand, with manual trading, executing trades at such high speed and accuracy is impossible.

2. Accuracy

Algorithms can process large volumes of data and recognise patterns that human traders might often overlook. This results in more accurate trading decisions than human traders.

3. Eliminating Emotions or Bias

Algo trading eliminates emotional and psychological biases. Emotions such as fear, greed, and overconfidence can cloud judgment and lead to impulsive decisions. By relying on algorithms, traders can stick to predefined strategies without being influenced by market sentiments.

4. Backtesting and Optimization

Algo trading allows traders to backtest their strategies using historical data. Backtesting enables them to refine and optimise their algorithms for better performance. Traders can analyse an algorithm’s past performance and make necessary adjustments to enhance its effectiveness in current market conditions.

5. Diversification

Algo trading enables traders to diversify their portfolios across multiple assets and markets, reducing overall risk exposure. Automated systems can manage multiple trades simultaneously. This allows traders to spread their investments across different strategies, asset classes, and sectors/industries.

What are the Risks of Algo Trading?

Although algo trading has many advantages, it is necessary to be aware of its risks.

1. Technical Failures

Algo trading relies heavily on technology, making it vulnerable to technical glitches, connectivity issues, or system failures. Technical failures can lead to significant and irrecoverable financial losses. Even a minor technical error can disrupt trade execution, leading to missed opportunities or losses. Poor internet connections or latency delays can impact trade execution and pricing.

2. Market Volatility

Rapid and automated trades executed by algorithms may lead to market volatility. Huge volatility can lead to quick crashes and unexpected market movements. In extreme market conditions, algorithms may develop market fluctuations due to their swift response to price changes, leading to market instability.

3. Over-Optimisation

Over-optimising algorithms based on historical data can lead to poor performance in real-market conditions. While algorithms may show good results in backtests, they may not adapt well to real-world market conditions. Therefore, over-optimising strategies may lead to underperformance. 

4. Lack of Human Oversight

Relying fully on algo trading without human supervision may lead to unforeseen and unexpected outcomes. Moreover, algorithms may not account for market events or black swan events outside the scope of historical data.

5. Lack of Human Judgment

Algorithmic trading relies on mathematical models and historical data. So it does not consider the subjective and qualitative factors that can influence market movements. In this case, the lack of human judgment can be a disadvantage for traders who prefer discretionary trading.

In conclusion, algo trading has revolutionised the financial markets, introducing speed, accuracy, and efficiency in trade execution. By removing human emotions and leveraging the power of computer algorithms, traders can capitalise on market opportunities with remarkable precision. However, algo trading does come with inherent risks, making it essential for traders to exercise caution. As the landscape of financial markets continues to evolve, algo trading will undoubtedly play an increasingly vital role in shaping investment strategies and market dynamics.
