Data Configuration

The chart reads market data through IBasicDataFeed.

Purpose

This is the part of the chart setup that connects your app to market data.

It tells the chart:

• which symbol data to load
• how to fetch historical bars
• whether realtime updates are available
• whether symbol search, watchlists, alerts, or depth data are available

Where It Is Used

The datafeed is used when the chart:

• starts up and loads the first symbol
• switches to a different symbol
• changes timeframe or resolution
• requests historical bars
• receives live updates
• opens symbol search
• creates watchlists or alerts when those features are available
