Check real-time data in Yahoo Finance for Web

Yahoo Finance provides real-time streaming quotes for many exchanges. Real-time data is available during an exchange's market hours, and in some cases during pre-market and post-market hours. However, not all markets will stream in real-time.

See whether a quote is real-time by checking the trading information below the quote price on the quote summary page. Observe the date and time, volume, and price change. You'll also know a quote is real-time when a red or green background flashes behind the stock price. A red background indicates the price is down and a green background indicates the price is up.
