TradingView is an in-browser platform and app for charting, monitoring cryptocurrencies as well as other financial assets. Its charting tools are also available for use directly in other platforms. In addition to charting, you can share your trading strategies and broadcast real-time analysis.
In terms of free features, TradingView is a powerful tool for traders with any level of experience. The basic features should be enough for most of them. However, be careful when studying other users' ideas and broadcasts. It is important not to blindly follow someone, but to find information that will add value to your own strategy.
