- Real-time price: The most recent traded price.
- Historical data: Price trends over specified periods (e.g., daily, weekly, monthly for the past year).
- Open, High, Low, Close (OHLC): The prices at which the stock opened, reached its highest point, lowest point, and closed during a trading day.
- Volume: The number of shares traded.
- Market capitalization: The total value of outstanding shares.
- Earnings per share (EPS): A measure of a company’s profitability.
- Price-to-earnings (P/E) ratio: A valuation metric comparing a company’s share price to its earnings per share.
- Dividend yield: The percentage return on investment from dividends.
- Company profile: Basic information about the company, such as its industry, sector, and brief description.
- Data Formatting: Presents the retrieved data in a user-friendly format, often as a JSON object, a Pandas DataFrame, or a custom data structure within the application.
Advanced Features

- Data Validation: Validates the retrieved data to ensure its accuracy and consistency, potentially flagging outliers or discrepancies.
- Customizable Data Feeds: Allows users to specify the exact data points they need, reducing the amount of data transferred and processed.
- Alerting: Integration with an alerting system to notify users when a stock price reaches a certain threshold or when other significant events occur.
- Integration with Analytical Tools: Seamless integration with other financial analysis tools within the application, facilitating charting, technical analysis, and portfolio management.
