I have no idea whether it is possible to make profit using trading bot. But I know that to make profit from trading you need to have good experience in trading otherwise you will have more losses instead of profit. There are some people who start trading without understanding. It is very difficult to make money from trading thinking that you have lost all your money. I think making money from trading is as difficult as it is easy. It is very difficult for people who start trading without understanding to make money from trading.
The bots are not using their brains but only automating the lengthy processes while also eliminating human error. So all the experience and knowledge you have remains as it is, the bots and tools are only helping you polish the skills and automate the process.
Not a fan of bots myself because of the type of trades I do. But in some cases, bots can indeed help you as I have seen it myself.
Eventually, it depends on how you trade and whether you need a bot to assist your trading. If you think a bot will make money by itself then you are mistaken because no such bots exist or they wouldn't sell it.
