Are you searching for something that is automated and will do the work for you or are you searching for something that could give you a notification when a certain coin reaches a certain value based on your specifications?
If it is the first option then I will suggest you not use such a thing for price prediction. When you rely on something other than yourself, it becomes complicated and the results are not going to be the one to your liking. People use bots or signal services but I never recommend anyone to use those. They can be accurate sometimes but not every time. And if you keep using those services, you will forget even the basics of trading in the long run. So don't use them.

But if it's the second option, there are services available that will keep you up to date but you will have to do it manually.
