Delayed and Streaming Market Data

Both streaming and delayed market data are available in WebTrader when you log in from the IB website (not when you log in from within Account Management).

Delayed Market Data

Delayed market data is available for instruments for which you do not currently hold market data subscriptions.
The next time you log into WebTrader, you will be prompted to turn on delayed market data for instruments for which you do not hold subscriptions. Your choice will be saved.
You can turn delayed market data on and off on the Market Data tab in the WebTrader Preferences window. So for example, if you opted to turn delayed market data on the next time you log into WebTrader, you will be able to turn it off in the Preferences window.

Streaming Market Data

Streaming market data is supported in the latest web browsers only. If your web browser does not support streaming market data in WebTrader, your market data will be refreshed every ten seconds.
The current status of your streaming market data is displayed on the Market Data tab in the Preferences window.
You can also set the number of decimal places to display for streaming market data on on the Market Data tab in the Preferences window.

Neither streaming market data nor the Market Data tab in the Preferences window is available if you launch WebTrader from within Account Management. You must log in to WebTrader directly from the IB website to access these features.

Streaming market data is supported in the latest versions of Firefox, Chrome and Safari web browers. At this time, it is NOT supported in any version of Internet Explorer.
