If you can use them and implement them in your strategy why not? And there's no reason to hype it up, it's been there for so long and people who know about it, know about it. They make trading easier (trading, not making profit) and give access to quite a few automations that make it easier in general for them. I've tried them before and they're definitely helpful.

And at the same time pretty sure a trader can still be one even without it. After all at the end of the day, a tool is just that, a tool. Something that helps, not something that guarantees.
