Has a minimal footprint that can reduce overall page size compared to multiple static images, offering a lightweight alternative without sacrificing interactivity.
Supports custom plugins to extend functionality beyond built-in capabilities, with interactive examples provided in the documentation.
Offers ES modules and IIFE bundles for different development and production needs, ensuring flexibility in integration.
Being canvas-based, it lacks native accessibility features for screen readers, requiring additional effort to make charts accessible compared to SVG alternatives.
The Apache 2.0 license requires displaying a TradingView attribution link, which might be restrictive for some commercial applications or projects avoiding vendor branding.
Primarily designed for financial time-series data, so it may not support common non-financial chart types like pie or radar charts without custom plugins.
