PineScript Render
PineScript Render is a VS Code extension for TradingView Pine Script developers. It provides static analysis, intelligent tooltips, and an integrated backtest preview panel powered by vectorbt — letting you visualize strategy performance without leaving the editor.
Features
Backtest Preview Panel
Run strategies directly from VS Code and view results in an interactive chart panel:
- K-Line Chart with trade entry/exit markers (Lightweight Charts)
- Equity Curve with benchmark comparison and drawdown overlay
- Metrics Bar — net profit, annualized return, win rate, Sharpe, Sortino, max drawdown
- Trades Table — sortable list of all trades with PnL, duration, exit reason
Shortcut: Ctrl+K V (or Cmd+K V on macOS) to open the preview panel.
Static Analysis
- Zero False-Positive Goal: Greedy symbol scraping handles partial parse errors gracefully
- Advanced Diagnostics: Catch void return assignments, argument count mismatches, namespace misuses
- Pine v6 Support: Full support for namespaces (
log., chart.point, UDT constructors)
Intelligent Editor Features
- Hover Documentation: Detailed reference for 800+ built-in functions
- Contextual Autocomplete: Organized by namespace (
ta., math., array.)
- Signature Help: Parameter hints as you type
- WASM Powered: Tree-sitter parser runs on WebAssembly for sub-millisecond AST generation
- Zero-Dependency Core: Bundled with esbuild, lightweight and fast
