Which function provides real-time data on securities trading intraday?

The Real-Time Quotes function is designed to provide users with up-to-the-minute information regarding the trading of securities. This function enables users to see price changes, trading volumes, bid-ask spreads, and other critical market data in real time throughout the trading day. This feature is essential for traders and investors who rely on timely information to make informed decisions quickly and capitalize on market opportunities as they arise.

In contrast, the Historical End of Day function focuses on data that are only available at the end of the trading day, which is not useful for intraday trading decisions. The Market Overview function offers a broader view of market trends and conditions rather than specific security data in real-time. The Equity Screening function is used to filter stocks based on various criteria but does not provide real-time trading data. Therefore, the Real-Time Quotes function is uniquely suited for intraday data, making it the correct choice.
