AI systems analyze data to find trading opportunities

To understand how AI transforms trading, it’s important first to appreciate the sheer scale of data that modern financial markets generate. Countless transactions occur across many exchanges, asset classes, and geographies every second. Each of these transactions contributes to a vast, ever-growing pool of data that includes price movements, trading volumes, order book dynamics, and more. Making sense of this data deluge is an overwhelming task for human traders.

Power of machine learning

Machine learning, a subset of AI, lies at the core of AI-driven trading. It emphasizes empowering computer systems to learn and enhance themselves based on experience without the need for explicit programming. In trading, machine learning algorithms are trained on historical market data to identify patterns, correlations, and anomalies that might signal profitable trading opportunities.

  • The supervised learning, where the algorithm is fed a labelled dataset – that is, data where the desired outputs (e.g., “buy”, “sell”, “hold”) are already known. The algorithm then learns to map the input data to these outputs, essentially learning the rules that connect certain market conditions to certain trading decisions. Once trained, the algorithm is applied to new, unlabeled data to make predictions and generate trading signals.
  • Unsupervised learning is where the algorithm is left to independently discover hidden structures and relationships in the data. This is particularly useful for identifying novel patterns or clusters in market data that human analysts might overlook. For example, an unsupervised learning algorithm might uncover a previously unknown correlation between the prices of seemingly unrelated assets, revealing a potential arbitrage opportunity.

Deep learning and neural networks

In recent years, a type of machine learning known as deep learning has gained significant traction in AI-driven trading. Deep learning involves using artificial neural networks and computer systems modelled loosely on the human brain to learn from and predict complex data. The power of deep learning lies in its ability to discover and extract high-level features from raw data automatically. In the trading context, a deep learning model learns to recognize complex, nonlinear patterns in market data without manual feature engineering. For example, a deep learning model trained on raw price and volume data might automatically learn to identify subtle signs of market regime changes or impending trend reversals.

RNNs are designed to handle sequential data, making them well-suited for analyzing the temporal dependencies in financial time series. By training an RNN on historical price data, for example, it learns to make short-term forecasts of future price movements, which can then be used to inform trading decisions.

Sentiment analysis and alternative data

Beyond traditional market data, AI trading systems increasingly leverage alternative data sources to gain a competitive edge. The prime example is sentiment analysis, where AI algorithms gauge market sentiment from unstructured data sources such as news articles, social media posts, and online forums.

These systems quantify market sentiment in real time by training a natural language processing (NLP) model to understand text data’s emotional content and context. This provides valuable insights into how market participants react to news events, company announcements, and other catalysts, potentially signalling short-term trading opportunities. Other alternative data harnessed by AI trading systems include satellite imagery, credit card transactions, and even weather data. The key is to find novel, informative signals in unconventional data sources that the broader market has yet to appreciate fully.
