There are two important things, when you use MFM7:
1.) Find a good broker
I think FXPIG is one of the best Broker for this EA. If you want to test them too, than please write me before you register for a special deal.
2.) Find good settings
The vendor itself already provide 'ready-to-go' settings that are updated by himself. But I think that are not the best settings you can get for this EA. It took me months to backtest all pairs with 99% tick data + variable spreads and find the best settings (in my view) for this EA / strategy. You can compare my settings and the original settings on my profile page.
