Key takeaways

The foundation of any successful trading AI lies in the quality and comprehensiveness of its data. Sourcing historical market data is the initial crucial step.

This involves identifying reliable sources such as financial APIs (Application Programming Interfaces) offered by brokers, exchanges, and specialized data providers like Bloomberg, Refinitiv, and Alpha Vantage. These APIs provide real-time and historical data on prices, volumes, and other market indicators.

Alternatively, databases like Quandl, IEX Cloud, and even custom-built databases can be utilized. The choice depends on factors such as data granularity (tick-by-tick vs.

daily), asset coverage, cost, and ease of integration. The data must cover a sufficient historical period to capture various market conditions and cycles.

Raw market data is often noisy and incomplete, necessitating rigorous cleaning and preprocessing. This stage involves handling missing values (imputation or removal), outlier detection and treatment (using statistical methods like z-score or IQR), and data type conversion (ensuring consistent formats).

Data normalization or standardization is vital to prevent features with larger scales from dominating the AI model's learning process. Techniques like Min-Max scaling and Z-score standardization are commonly employed.

Additionally, resampling data to different time frequencies (e.g., from minute-level to hourly) can be necessary to align data sources or reduce computational complexity. Careful attention to data quality at this stage directly impacts the model's accuracy and reliability.

Feature engineering is the art of transforming raw data into meaningful features that AI models can effectively learn from. This involves creating new variables that capture relevant patterns and relationships in the market.

Examples include technical indicators like Moving Averages, Relative Strength Index (RSI), MACD, and Bollinger Bands. Lagged values of price and volume are also frequently used.
