Hi all. Personally I don't think there's a ideal pair to trade - it's a matter of what you'd rather. Barring news/economic occasions, a few pairs have better trend movements than others, a few range a lot more, etc., etc..
IMO - you should trade what is suitable to you. My issue is I am fairly new to Forex and I really don't understand which pairs I can trade in the days of the day that I'm awake.
My timezone is -5GMT and EUR/USD appears to be more active throughout the 2AM-8AM period for me. I do not mind USD/JPY as a lot of men I've spoken with seem to dislike it.
The suggestion I would make from a newbie point of view is to pick a couple pairs and learn them. That way you understand their patterns on the technicals and have an notion about what to anticipate the fundamentals.
I've attached a few screenshots simply to display - it doesn't really matter the pair you trade. You can make profit off some of these. The spread/swap/technicals/fundamentals may change how things go, but you simply have to find your trading platform and stick with it.
My 2 cents.
