The primary function of TradingView is analyzing price charts of various financial assets. But it also provides a large selection of tools for technical analysis. The secondary function is an analog of a social network. Users can share experiences, information, and even show their analysis of assets in real time. There is a free version as well as a paid version.
In the free version of the platform, almost all features are available, but with limitations. For example, only one extended watch list and one indicator calculation on another indicator, using no more than three indicators per chart, saving one chart, using one template for indicators are available. But they are also useful auxiliary tools for a trader. In the basic version there is quite a large number of useful features.
