DislikedCareful who you call a jerk my friend.
If you have ever run short term EA's before, then you'll know the difference between live and demo accounts can turn a great looking EA on demo into an account killer on live.
Test on live with micro lots. If it's no good, then I'll lose maybe $10. If you can't aford to lose that you shouldn't be trading, let alone trading FX.

I will always prefer to demo first, because in demo i can blow as many accounts as i wish to.
i have seen many great systems which fail when you put them as an ea.
even the ATC championships winner "Better" his EA failed miserably on live accounts.
