You can search for it in the telegram search menu to find telegram signal groups, but you might find it difficult to find them because each group you find will claim that their group is the best. Also, as far as I know, signal groups like that require a subscription fee to get lots of signals from them. But it doesn't guarantee you can get trading signals. So I advise you to learn about trading so that you don't depend on other people's signals and can trade freely.
Telegram is the origin of their main trading channels and communities, which are mostly controlled by pro traders and market influencers. Based on traders who are unwilling to thoroughly study trading related PDFs and also gather more knowledge, they served as the dependent clause in the space, always looking up to an influencer before placing any trade, it's more like copy trading. Trading using signals is one of the simplest ways to begin making money in the space althoughit'snot 100% guaranteed. It is apparent that most merchants face these organizations rather than rely on them and study it on their own.
