New technologies such as AI and machine learning are not just buzzwords. Tools based on them have been in common use for several years now. AI-based algorithms can be found in search engines, social media, streaming platforms, and even the medical sphere. Not surprisingly, the field of finance and investment has also been influenced.
This FXOpen article offers a closer look at modern machine learning (ML) algorithms for forex trading. You will learn about their application for trading currencies, their pros and cons, and their particular use cases.
Machine Learning in Forex
ML is a subset of artificial intelligence that uses algorithms to analyse and learn from data. Machine learning in forex trading and market analysis can be used to identify patterns and trends in market data to help traders make informed decisions. This technology is effective for predictive modelling, sentiment analysis, risk management, portfolio optimisation, and high-frequency trading.
Some of the popular ML algorithms used in FX market analysis include decision trees, random forests, and neural networks.
- Decision trees use tree-like structures to model decisions and their possible consequences. They are used to identify the most important factors that affect currency prices and determine future trends based on historical data.
- Random forests are an extension of decision trees that use multiple trees to generate more accurate forecasts. They allow you to minimise the risk of overfitting.
- Neural networks are based on the structure and functioning of the human brain. Traders use them for pattern recognition, classification, and regression.
Pros and Cons of Using AI for Forex Trading
Compared to traditional forex analysis methods, machine learning offers several advantages. For example, machine learning algorithms can process large amounts of data quickly and accurately, potentially making it easier to identify patterns and trends. Additionally, machine learning can help traders make more objective decisions by removing biases that may be present in traditional analysis methods.
However, there are also limitations to consider. If the data is incomplete, inconsistent, or biassed, it can lead to an inaccurate analysis. Additionally, it can be difficult to interpret and understand how the model arrived at a particular conclusion or decision. The theory states that ML and deep learning forex trading algorithms should be used in conjunction with other analysis methods for the best results.
The next few sections are devoted to the study of machine learning applications in forex analysis. One of the most common cases of using machine learning is predictive modelling. Such models use historical data to determine future price movements. There are two main approaches to building predictive models: supervised learning and unsupervised learning.
- Supervised learning means using labelled data to train a model. This might involve using historical price data to train a model to determine future price movements.
- Unsupervised learning, on the other hand, involves using unlabelled data to identify patterns and relationships in the data.
Feature selection and engineering are also important considerations when building predictive models for forex analysis. Traders decide which features to include and how to engineer those features to maximise predictive accuracy.
Also, it is important to use accurate historical quotes. These can be found for many assets, from currencies and cryptocurrencies* to stocks, on the TickTrader trading platform.
A code that processes currency pair quotes is not the only forex trading artificial intelligence algorithm. For example, sentiment analysis involves using natural language processing (NLP) techniques to analyse text data. Such algorithms are similar to what popular ChatGPT does.
In forex, sentiment analysis can be used to extract insights from news articles, social media posts, and economic indicators. By incorporating sentiment data into their trading strategies, traders can better understand the market mood and make informed decisions. However, it is important to note that even a popular opinion should not be followed blindly, and it is important to analyse everything for yourself.
Risk Management and Portfolio Optimisation
Machine learning can also be used to assess and manage risk in forex trading. When the algorithm analyses historical market data, it identifies and summarises common price patterns, including average volatility, that may help traders manage risk. Models can be useful if you need to develop a trading strategy.
In addition, traders use ML to optimise trading portfolios. The goal of the algorithm will be to determine the optimal balance between risk and return. This can include identifying which assets to hold, when to buy or sell, and how much of each asset to hold.
High-frequency trading, HFT, involves using algorithms to execute large numbers of orders at high speeds, typically within seconds. HFT uses machine learning to determine short-term price and liquidity changes automatically. AI-based tools are used to develop HFT strategies that take advantage of market inefficiencies and potentially generate opportunities. Machine learning is also used for risk mitigation, hedging, speculative strategies, and volatility estimation during HFT.
However, HFT also comes with its own set of challenges, including the need for high-speed data processing and the risk of errors caused by algorithmic trading. A study found that machine learning procedures may be unable to find high-dimensional patterns in the order book that could be used for trading purposes.
Machine learning offers many advantages for forex analysis, including the possibility to process large amounts of data quickly and accurately. As ML continues to evolve, we can expect to see even more applications of this technology. For example, reinforcement learning, which involves training models through trial and error, could be used to develop more advanced trading strategies.
However, it is important to remember that this is not a silver bullet, and it should be used with other analysis methods. If you already have some analysis techniques, you can open an FXOpen account and leverage advanced tools.
