Hi Steve, thank you for your post..
You are almost right. This afirmation: 'most scalping EA's that work on demo accounts struggle on a live account.' is right in most of situations, but not in mine.
I have real accounts running just this EA for me (actually I am analist of systems from a company here in Brazil, so I don't have time to do trades since March 2010). This accounts are mine and from my friends here of the company.
I am trader since 2006 and I know what you are talking about, and I agree.
Well, why don't I put the REAL results here?
The answers is a quite simple: What guaranty do I have that are theren't system that does copies of orders here?
Is really complicated.. As you know, this system (MyFxBook) connect on our broker with our password to verify each trades and validate it. So I preffer leaves my real accounts far away from this kind of systems.
