TradingView is a widely used charting and social-analysis platform, valued for its clean, highly customizable charts, large library of community-built indicators, and its own scripting language (Pine Script) for building custom tools and strategies. Many brokers now offer direct trade execution from within TradingView's charts, rather than requiring traders to switch to a separate platform.
TradingView is often used purely for analysis and idea-sharing alongside a broker's native execution platform, even by traders who don't place any actual orders through it.
