An experimental open-source desktop charting application. Supports Binance, Bybit, Hyperliquid and OKX
- Multiple chart/panel types:
- Heatmap (Historical DOM): Uses live trades and L2 orderbook to create a time-series heatmap chart. Supports customizable price grouping, different time aggregations, fixed or visible range volume profiles.
- Candlestick: Traditional kline chart supporting both time-based and custom tick-based intervals.
- Footprint: Price grouped and interval aggregated views for trades on top of a candlestick chart. Supports different clustering methods, configurable imbalance and naked-POC studies.
- Time & Sales: Scrollable list of live trades.
- DOM (Depth of Market) / Ladder: Displays current L2 orderbook alongside recent trade volumes on grouped price levels.
- Comparison: Line graph for comparing multiple data sources, normalized by kline
closeprices on a percentage scale
- Real-time sound effects driven by trade streams
- Multi window/monitor support
- Pane linking for quickly switching tickers across multiple panes
- Persistent layouts and customizable themes with editable color palettes
- By default, it captures and plots live trades in real time via WebSocket.
- For Binance tickers, you can optionally backfill the visible time range by enabling trade fetching in the settings:
- data.binance.vision: Fast daily bulk downloads (no intraday).
- REST API (e.g.,
/fapi/v1/aggTrades): Slower, paginated intraday fetching (subject to rate limits). - The Binance connector can use either or both methods to retrieve historical data as needed.
- Fetching trades for Bybit/Hyperliquid is not supported, as both lack a suitable REST API. OKX is WIP.
Standalone executables are available for Windows, macOS, and Linux on the Releases page.
