I did some testing with MiEA 9.0 using MT4 Strategy Testing, it is quite profitable (easily 100% profit gain with maximum drawdown at about 30%) but MT4 Strategy Testing only allows you to test on 1 pair, which does not really serve the right purpose of MiEA 9.0.
From the look at it, it seems like trading one pair is more profitable than trading all 8 pairs simultaneously. However, I don't know how to configure it so that it only trades 1 pair in real live trading. Anyone knows how?
