I am using the 3commas bots. You can automate your strategy using the trading language view "pinescript" to parameterize your strategy.
I have seen some comments that bots are not profitable and that human intelligence beats them. From my experience humans are not able to open a position if the conditions of 10 indicators (or more) are met, or what is the same, to be able to replicate the behavior of a good bot you have to be all day watching their charts.
My experience with 3commas has been very positive, I have been with them for about 6 months and with a good risk management profile the profits are constant. Miracles do not exist, but a good risk management and a well configured bot is a way to generate good passive income. For any questions you have the telegram or discord community, which is very active. I would recommend it if you do not have any in mind.
