In the first place, trading bots should mostly just be used to decrease your trading work,
As for OP's question, this is the primary function of bots. It only helps you, the trader to take yourself off from screen. It doesn't mean that using bots means big profit. Bits are configuration and can trade even negative and give loss.
I have noticed from my own experience that when the market goes up, trading bots do an excellent job, bringing profit on each trade. But when the market falls, trading bots do not keep up with the price movement and do not have time to close the deal.
