Quote from KirkVosper:
You can also order them from lowest to highest. If the spread is low on EUR/USD it will probably be low on the other pairs too.
Recently GFT has the best spreads, I think. 1pip on majors, am I right?
BUT KEEP IN MIND, that this, although very important, is as much important as:
1.platform stability (f.e. often disconnects at Oanda),
2 customer support,
3.rollover rates (terrible, very terrible with GFT mini-acconut),
4. and foremost - TRADE EXECUTION!
(5. others)
When either of these points are poor, it adds up to the costs more than a neophyte would think!
