I was really going through hard time trying to get all the profits I can think of, without thinking of learning more. I did copy trade with a robots traders called Zulu, all I was thinking is that this robots don't fails since they're humans but apparently I was wrong, robots do fail as well because they're programmed by humans.
I've encountered two people as well who engage in the use of trading bot for their daily activities while determining their trades for them, but we need to understand one important aspect which you already mentioned that the bots where programmed and also by human Which means though you may buy one and enjoy little advantage but remember that they can't go off their limit to how they have been set up or programmed.
