Hello guys I appreciate your opinion, for simple use buy sell and using trailling function.best is 3cmmas or Corninx
Do you mean 3commas? If so, they are famous and have a long history, but make sure you do not use the CMC API, as it sometimes leads to losses, and at the very least, your personal data will be leaked

I haven't heard of Corninx so it's best to avoid it.
There are many options, open source or closed source, such as Gunbot
