It’s 3:00 AM. Your algorithm just extracted and processed 12,000 news headlines about the Fed rate decision while you were asleep. The market opened 15 minutes ago, and your strategy is already executing trades based on this data—without a single manual intervention. This isn’t science fiction. It’s the power of data extraction tools in modern algorithmic trading. Data Extraction is the process of retrieving data from unstructured or poorly structured sources for further processing or storage. It’s the critical first step in transforming raw market information into actionable trading signals. Without it, even the most sophisticated algorithms would starve for data. Data extraction isn’t just about pulling numbers from spreadsheets. It’s about systematically retrieving information from chaotic, unstructured sources—like news feeds, social media, or even PDF earnings reports—and converting it into a format your trading platform can use. This process typically involves three phases: extraction, transformation, and loading (ETL).
