How do I view Real-Time and streaming chart data?
Streaming and Real-Time data cannot be viewed on Interactive, Basic, or Basic Tech Analysis charts. Instead, these features are only available as part of the Yahoo! Finance Real-Time Quotes package on the premium chart feature in MarketTracker.
To use the premium chart, you need to be a Real-Time Quotes subscriber. If you are already a Real-Time Quotes subscriber, you can view Real-Time and streaming data by launching MarketTracker and opening its premium charts.
