For me a holy grail would be a simple system that you can play automatically like a robot without too much thinking and no personal decisions are made.
it must win in the long term with a nice profit and normal drawdowns.
Bu I don't think a system like that exists.
Sounds a bit lazy to me, wanting a bot to do it for you, i wanted a bot a short while ago, but now, id never go near one, id rather sit in my pj's, work for 2-3 hours and earn that profit, anything over £7 an hour long term has to be seen as a success as thats already more than minimum wage in the uk lol
