A stock ticker is an automated system that consistently displays current stock market data, including ticker symbols, prices, and transaction volumes, typically in real-time. The primary objective of a stock ticker is to provide investors and traders with immediate insights into market movements.
Key Features
- Ticker Symbol: This is a unique series of letters assigned to a security or stock for trading purposes. Examples include ‘AAPL’ for Apple Inc. and ‘GOOGL’ for Alphabet Inc.
- Price Information: Displays the last traded price of the stock, often alongside the price change from the previous trading session.
- Volume: Indicates the quantity of shares traded in the latest transaction or over a specific period.
- Real-Time Updates: Most modern stock tickers update continuously to reflect live market data.
