There are no such things, bot usually do as your setting do, there are not work well or not thing in bot. That is all matter of luck if you can get profit or busted all of your coin
A bot is no more smarter than a human being who set it up. The only difference is that it is programmed. So it is very disciplined, it is not affected emotionally. It will do thing you tell it to do, without changing the course. A human gambler's judgement will be affected by environmental factors.
