Which type of market data is of most interest to a trader for executing trades?

• A. Real time quotes and news to facilitate the trading function
• B. Regulatory filings data to ensure compliant trading
• C. Investment research to determine if a security is worth trading
• D. Historical documents and manuals

Answer: (A)

For executing trades, timely market data is essential because it shows current prices, quotes, and news that drive when and how you place orders. Real-time quotes reveal the live bid and offer, the last trade price, and current trading activity, which are needed to determine the best execution venue, the right price to act on, and how quickly you must move in a fast-moving market. Real-time news can also trigger quick price moves, so staying updated helps you react promptly. Regulatory filings data, while important for understanding disclosures and compliance, doesn't guide immediate order timing. Investment research informs whether a security is worth trading, but it often involves analysis that isn’t in real time and doesn’t directly affect the moment-to-moment prices or liquidity. Historical documents and manuals provide background and procedures, not current market dynamics. So, for the task of actually placing trades, real-time quotes and news are the most directly relevant.
