In the fast-paced world of finance, where every second counts and fortunes are won or lost in the blink of an eye, there’s a powerful technique that exists they not many people have taken full advantage of — Algorithmic Trading.
Traders equipped with cutting-edge technology, leveraging intricate mathematical models and artificial intelligence, executing trades with pinpoint accuracy, all while sifting through mountains of data in real time. Meanwhile, traditional traders are left in the dust, struggling to keep up with the lightning-fast pace of the market. If you’re looking to get with the times and get up to speed on what algo trading is all about, you’re in the right place.
In this blog, we break down what algorithmic trading is, how it works, and what kind of skills you’ll need to wield it.
What is Algo Trading?
Algorithmic trading aka algo trading is a method by which a trade is executed by a computer program (an algorithm) when a predefined set of conditions is met. The basic idea is that you can create algorithms to execute trades automatically when they match the rules you’ve defined in trading strategy like the exit and entry times, stop loss orders, and price movements.
Trades can be executed in a matter of seconds meaning that the trader enjoys economies of scale by making decisions to buy or sell way faster than a person deploying strategies manually.
The use cases for algorithmic trading go above and beyond deploying a trade, you can use it for
- For decision-making (Conducting technical analysis, charting, market scanning, automatic trend detection, tick & volume analysis, getting market alerts)
- Conducting backtesting (Running simulations to test your algorithms effectiveness in different indexes)
- Order execution (Buy or sell trades when predefined conditions are met)
- Execute trading strategies like arbitrage and trend trading.
Processes vast amounts of data — Algorithms can process vast amounts of data and make trading decisions in a matter of milliseconds, allowing for quick reactions to market changes and the exploitation of short-term price movements. This speed advantage is particularly important in highly liquid markets where prices can change rapidly.
Truly rational decision-making — Another benefit of algorithmic trading is its ability to remove human emotions and biases from the trading process. Emotions such as fear and greed can often cloud judgment and lead to irrational trading decisions. By relying on pre-programmed rules and algorithms, algorithmic trading eliminates the emotional component and ensures that trades are executed based on objective criteria.
Algorithmic trading uses sophisticated mathematical models, and statistical analysis combined with the power of machine learning and artificial intelligence to execute trades that have a higher chance of getting favorable outcomes.
In order to understand how algo trading works, we must first look at its evolution.
- Our bias stops us from succeeding: Here’s an oversimplified version of the trading process. First, you do a fundamental analysis of companies to finalize a trading strategy. Rely on gut feeling after the analysis, then decide to place the order, then execute it. But, note that people don’t always act completely rationally in the financial market because of a very human nature — we’re made up of our biases and judgments of the world. So humans are more prone to misjudgments or misinterpretations when making decisions even after doing the fundamental analysis.
- Let math lead the way: To remove such biases, systematic trading was invented. Systematic traders use quantitative models and historical data to identify trends in the market that they can capitalize on. They perform calculations manually based on charts and analysis which takes a considerably longer time, but it gave rise to the era of high-frequency trading, which investment companies often used to do to gain a competitive edge in the market.
- Backtesting trading strategies takes time: Not only did they take incredible time to calculate probabilities, but they also needed to backtest these strategies to learn how effective they were on the markets, which again takes time.
- Introducing AI- and ML-powered quantitative trading: Now these calculations take a lot of time and computing power. So, developers created codes to execute these algorithms so that the calculations could be executed within seconds. The processes of both quant analysis and backtesting can be automated by writing algorithms for them.
Some common strategies you can use in algo trading include trend following, mean reversion, statistical arbitrage, and market making.
- Trend-following algorithms aim to identify and capitalize on long-term market trends, while mean reversion algorithms look for opportunities to profit from the reversal of short-term price movements.
- Statistical arbitrage algorithms seek to exploit pricing inefficiencies between related financial instruments, while market-making algorithms provide liquidity by continuously buying and selling securities.
These are just a few examples of the many strategies that can be employed in algorithmic trading, and traders and fund managers can choose the strategies that best suit their investment goals and risk tolerance.
Once the trading signals (aka the indicators aka the predefined criteria) are generated, the algorithms automatically execute trades by sending orders to the market. This is typically done through electronic trading platforms or direct market access (DMA) systems.
Here’s a step-by-step guide on starting algorithmic trading as a beginner.
Which language is used in algo trading?
Some widely used languages to create trading algorithms include
- Python, (easy to learn, access helpful libraries, and strong community)
- Java, (platform independence, allows algorithms to run on various systems without modification)
- C++, (high-performance capabilities, enabling low-latency execution crucial in high-frequency trading environments)
- R. Python (extensive library ecosystem and readability)
Algorithmic Trading can be done on algo trading platforms like MT4 or ProRealTime software or by using API provided by bleeding-edge software companies like Creed&Bear on online trading applications. It depends on what kind of user you are.
Algo trading is mostly used by institutional investors or large brokerage firms who are looking to capitalize on minute changes like the super fast deployment of trades to shave off time taken to make trades or profit off small changes in price. Research suggests that algorithmic trading is found to be a cost-effective technique, but it applies only to order sizes that are up to 10% of the average daily trading volume.
For such traders, APIs are more suitable since they can be personalized to your particular needs. However, if you’re an individual trader, you could go for electronic trading platforms that offer algo trading programs like the ones we mentioned earlier.
There are several key skills that are essential for success in algorithmic trading. Depending on whether you’re trading to fuel your own interests or you’re part of larger fund management companies, the skill requirements may vary.
Most times algo trading is employed by fund managers of larger asset management companies or financial institutions, so they don’t really need to know a lot of coding as there are companies that offer software solutions they can directly apply to their trading platforms.
Here are some basic skills needed for algo trading:
- Understanding of the financial markets: Knowledge of financial markets and trading strategies is crucial. Algo traders need to understand how different markets operate, the factors that influence price movements, and the various trading strategies that can be employed.
- Quantitative analysis: Algorithmic trading relies heavily on data analysis and mathematical modeling. Traders need to be able to analyze large datasets, identify patterns, and develop mathematical models that can predict market movements. Strong analytical and mathematical skills are therefore essential.
- Econometrics: The study of econometrics allows you to analyze and model complex financial data. It combines economic theory, statistical analysis, and mathematical modeling to understand and predict economic phenomena. This could be really useful when understanding the relationship between different variables in the financial markets. Trading models developed through econometrics enable you to quantify the impact of various factors on asset prices, such as interest rates, inflation, or market sentiment. It also helps you assess the risk and return of your trading strategies–like estimating the volatility and correlation of different assets, which are crucial for portfolio management.
- Risk management: Algorithmic trading involves executing a large number of trades at high speeds, which can increase the risk of financial losses. Traders need to have a thorough understanding of risk management techniques and be able to implement effective risk mitigation strategies to protect their investments.
- Knowing programming languages: One of the most important skills is a strong understanding of coding. Algorithmic trading involves developing and implementing complex trading strategies using computer programs, so having a solid foundation in programming languages such as Python, C++, or Java is crucial.
- Keeping up to date with news: So, while this isn’t technically a skill, this is probably one of the most crucial aspects of being any kind of trader. Stay up to date on what’s happening in the world. Most political and business updates always have an impact on the financial markets. This is crucial for understanding market sentiments.
Algo trading may seem like a lot. But in reality, it’s a simple concept if you understand trading already. As we wrap up our learnings, it’s important to remember that algorithmic trading isn’t a magic bullet, but rather a sophisticated tool that requires careful planning, adaptability, and a lot of unlearning and relearning. It’s a field where innovation never rests, and staying on top of the latest developments is key to thriving in this dynamic environment. With the mushrooming of AI and ML, coders today can leverage the power of deep learning to reiterate their algorithms to get more favorable outcomes.
