Dude, search for Gunbot tutorials. It's a mainstream bot (which means there will be quality guides out there, even here in the forum there might be some quality info) and it covers most (if not all) config inputs you'll find on luna or other similar bots.

I quickly found this on google, didn't give it a full read but seems like a nice place to start learning: https://thecryptobot.com/category/gunbot-tutorials/

Check it out or just use the standard config that comes with Luna. It's pretty safe in my experience and delivers a few percent every week.
