Sorry to be so blunt, but chances are that you are failing, and there’s a multitude of reasons why that may be the case. But the one reason that ties the majority of failing traders together is this: They don’t believe the truth.
This brings to mind the saying: “A good ROBOT follows his rules; a great ROBOT knows when to break them.”

I have stopped selling my system.
I am now only renting my EA to traders who love scalping!
