Brokers often limit traders in choosing a trading platform. Their proprietary software can be inconvenient and limited in features. TradingView gives traders the ability to personalize their charts as much as possible. In addition, TradingView is also a social platform. You have the opportunity to join discussions, follow other traders' trades, and read a lot of other content that is constantly being created by the community.
The professional version of TradingView doesn't come cheap. But for serious traders who want to use the best software, it can be a good investment.
