TradingView

TradingView completely shattered the global financial software industry by approaching charting not as a clunky piece of desktop software, but as a hyper-modern, beautiful, HTML5 web-based "Social Network" for traders. It is the absolute undisputed most popular charting website on the entire internet, used by tens of millions of people daily. Its signature feature is its "Pine Script" language and the resulting "Community Scripts" massive open-source library. A brilliant trader in Brazil can write a complex momentum indicator in Pine Script, publish it to TradingView, and instantly, millions of users globally can apply that indicator to their own charts for free. This massive crowdsourcing of financial intelligence destroyed the monopoly of expensive, proprietary indicators. While it started purely as a charting tool, it has aggressively evolved into a true Brokerage Trading Platform. A trader can now securely link their OANDA, TradeStation, or Interactive Brokers account directly to TradingView. They can execute massive financial trades directly from the beautiful TradingView web chart, completely bypassing the clunky, terrifying interfaces of the legacy brokers.
