Should you be working on a system that is like no other? Should you be trading a system that does not even come close to another system?
Can you find a system that is really bad and trade it in reverse? (To Some Degree)
And no, you can't find a system that is really bad and trade it in reverse. If a system is really bad, then it more than likely just generates random signals. And random signals traded in reverse are still random signals.
