I am still in the demonion stage but plan to go live in the spring sometime. At this time I am mainly monogamus with EUR/USD. I began with USD/JPY but switched because there was more info on the Euro easly available on the net.
What I am looking for now is: What place (or sets) of currency pairs cancel each other well. Like are the cable and swissy enough different to exchange both and never get killed in one fell swoop. This sort of thing.
