I'm new to using FSB but from watching Popov's video's I have learned that demo accounts use different servers than do live accounts and therefore the results will be different.  Also I think that the demo account should be the same size as the account you are going to be trading live so that the lot sizes used will affect trading in the same way.  Therefore once you have tested on a demo account the EA's should be retested in FSB using the symbol data imported from the live trading account trading platform.  My thoughts...
