What do you like best about TradingView Charting libraries?
• Highly modular architecture with three distinct JavaScript libraries—Lightweight Charts, Advanced Charts, and Trading Platform so I can match component weight to project scope without re-engineering core code bases. The open-source Lightweight package delivers responsive HTML5 charts in ≈35 KB while the proprietary tiers add 100+ built-in indicators, 80+ drawing tools, multiple layouts, and integrated order-routing APIs for brokerage workflows.
• Clean, framework-agnostic embed. A single script plus a JSON-style widget constructor spins up a fully interactive chart; the same bundle slots into React, Vue 3, Next.js 13, or even Rails, thanks to the official integration examples on GitHub. Two-way data binding happens through a lightweight UDF/Streaming Datafeed interface, so I can wire in WebSocket quotes or historical REST endpoints with minimal glue code.
• Native support for 17 financial chart types (candlesticks, Heikin-Ashi, Renko, Point-&-Figure, etc.) and granular UI hooks. I can override color palettes, toolbars, right-click menus, and hotkeys, then persist user layouts via local storage or a backend of choice. CSS isolation keeps the library’s styles from bleeding into the surrounding app shell.
• Performance is rock-solid on both desktop and mobile. High-frequency panning and zooming stay fluid even when pushing real-time ticks every 100 ms, and the library automatically throttles DOM repaints to preserve 60 fps scrolling on lower-power devices.
• Vendor-agnostic licensing approach. Lightweight Charts ships under Apache 2.0, which removes legal friction for personal or commercial MVPs. The commercial licenses for Advanced Charts and Trading Platform include white-label options so I can strip the TradingView watermark when required for enterprise branding.

What do you dislike about TradingView Charting libraries?
• Initial setup still requires a private ZIP download through an access-controlled portal. Grant provisioning can stretch to several business days, which slows prototype timelines in corporate environments.
• Documentation depth varies. Core API pages are well written, yet edge-case behaviours (e.g., synchronising multiple sub-charts or intercepting crosshair callbacks) often demand reading TypeScript definitions or community threads for clarification. Review collected by and hosted on G2.com.
