We still have profitable robots. Some traders lose because of lack of emotional control, fear and indiscipline but robots are immune to all of these factors. Take a profitable manual system, code it to the robot, it will still be profitable. and actually I honestly don't like trading on the forex market using robots. I like to trade with my own skills and knowledge rather than using any robot and my own skills and knowledge are the best of any robot but I think of using robots in my trade.
