There are alot of signals channels and groups on telegram, though some are private which you will have to pay to become a member but some others are free but you can hardly make any significant profits from those free ones, and another thing is that the private ones cost really much but if you can afford it, good for you, but for me, I don't think it's worth it.
Incase you are intrested, you can simply use the search function on telegram to search for signal group or channels, you can also do same on Google and you will find many, there are also some signals channels on Twitter, so depends on your platform of choice.
