How to tell if real-time data is displayed on Yahoo Finance
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- and post-market hours. Not all markets stream in real-time.
Check for real-time data
See whether a quote is real-time by checking the trading information below the quote price on the quote summary page.
Mobile apps and mobile website
Below the quote price on each quote summary page you'll see the related exchange, and whether the quote is real-time or delayed.
