Data Window

The Data Window module provides a comprehensive panel for viewing and analyzing raw market data. It displays historical price bars, tick data, and other market information in tabular format.

Key Features​

  • Historical bar data display (OHLCV)
  • Real-time tick data streaming
  • Data export functionality (CSV, Excel)
  • Customizable column selection
  • Timeframe filtering
  • Data search and filtering

Architecture / Behavior​

The Data Window module is implemented as a right sidebar panel that fetches historical data through the data feed's getBars method and subscribes to real-time updates via subscribeBars. It maintains internal state for the displayed data and uses the GlobalStore for data-related state management.

API Usage​

Initialization​

The Data Window module is enabled by default in the chart configuration:

const chart = Chart.create(document.getElementById('container'), {
  // ... other options
  enabled_features: ['data_window'], // Enable data window panel
});

Methods​

The Data Window module automatically displays crosshair and bar data. It does not provide direct API methods for data retrieval, but supports:

  • Crosshair data display (automatically shown when cursor moves over chart)
  • Main series data (OHLCV values)
  • Compare series data
  • Indicator values
  • Real-time updates as data arrives
