Personally, I find TradingView to be a great platform for practice. It provides accurate data, and so far, I haven’t encountered any bugs or issues that could disrupt the experience. They also offer affordable plans for those interested in accessing some of their premium features. Just to be clear, I’m not advertising the platform, this is based purely on my own experience. And yes, it’s completely free if you don’t want to spend any money. It’s really up to you.
