Surprised to see a stock trading course, Petko! The EAs are already on my small live account where I test.
Recently I test the EAs not on Demo but on my live account with 0.01. I found that this is the better choice for me because I struggle to find a broker with same Historical data on Demo and Live server.
So when I tested the EAs on Demo and after that I move to live account, the results did not match every time.
