LOL, I'm not motivated much any more, after 34 years of it, rather play marbles, watching a dripping sink is more fun than trading the same patterns. Hiring other people was best move for me, let someone else do the backtesting/trading...
It doesn't matter any more what instrument you trade, you stare at it look enough, you learn it's personality and make money trading it.
The "edge" is really different at stages in one's life, after you truly learn how to trade and find out "this is it", that's all I had to do to be profitable, it is a let down, shit, I knew all that in my first year. But you convince yourself that the brightest are smarter than you and you have to design complicated methods, spend years redesigning the wheel, trade like a madman, over trade. That is all wrong, less is better, less trades and less time doing it. Make a steady consistent 2-4 points in ES and build up size and quit for the day.
Well, got to go pick up the marbles I dropped, ROFL.
