Hi Danny
You can download the Top 5 from Robot App, those Top 5 will be based on the last 10 years. Then, you test them in a demo account. After a week, you can see on the char itself, the performance of all of the 5 EAs and then you pick up top 3. You can keep those 5 EAs ongoing in your demo account and keep changing the top 3 from the last week into real challenge account.
