Quote from ArchAngel:
Just a hypothetical -
Suppose you had a real working system that was making you $200K a year trading the ES. Now suppose you find that you can sell/rent it to the public for a million dollars or more a year.
What would you do?
Would you're deciding to take the million a year instead of continuing to trade it (or even if you also continued trading it) invalidate your system?
I'll sell/rent it...
Simply becomes, why you make systems... to make money or for egoistical sense.
