I'm not really sure about it, bots can easily figure out some technical analysis in an instant that I can't do but there are some times about decision making that only I can decide. Actually both trading both and I are the same, I set up the details to him and he executes it in other words the input to the bot is what's on my mind so I think we're both the same.
There are things which bot cant do which is on that emotional aspect where you can change out decisions basing up on market condition which bots cant able to determine such thing which is understandable.
You do set up the bot and they'll do the work on what you had instructed or mandated but due to some factors like emotional then this is something that cant be controlled.
Bots are better in terms of executions of commands but it would always vary on the user itself about how its been set up and the effectiveness would really vary.
