But as far as I know, every black box bot gets rekt at some point without the involvement of human, I would be glad to see if you find such a bot and seeing it working.
That's why I look at the equity chart for months of forward testing, because I can tell if it will rekt itself. Rest assured, there are indeed strategies which are viable for months/years and they never rekt. Worst case they stop producing profit and then search for a new strategy.
