Which pairs to trade?

I am looking to trade just four currency pairs,on 4h and and daily charts. I have not yet fully decided upon the 'system' I will use but can any of you experienced traders give me any advice of the best four pairs to trade?
Obviously I wish to diversify my risk so pairs that do not move in a similar way would be preferred.
may I also take this oportunity to thank all you guys who offer your advice so readilly and freely.
This forum is wonderful and shows the tremendous generosity of the trading community.

Just trade the majors you'll have the thightest spread.
EUR/USD, USD/CHF, GBP/USD, USD/JPY

If you want independet pairs look for a correlation tabel on google.

Thanks Tjpld

i would also recommend trading EURJPY and GBPJPY, they have high volatility and thus high potential for returns, but also higher risk. observe these currency pairs for at least 2 months, see how they move, get a feel for them etc and then try trading them on demo. trading these 2 pairs can be very rewarding

I'd say "Stick to ONE pair, maybe two".
Pairs are like women, you date one and after 2 years you know what she's going to complain about before she even opens her mouth". Understanding ONE woman is difficult enough.
Every pair is very very very very very different.
I like two. My wife is EUR/USD, my mistress is GBP/JPY.
With my wife I have stability, tight spreads, I like to look at her and every day I learn one bit more about her imposible-to-understand personality.
My mistress is wild, loves action, risky, volatile.
I spend my life with her and I'm very happy.
However, every now and then I visit GBP/JPY for a wild night stand.

Pairs for illustrative purposes only
I believe in marriage, being faithful and loyal.

I'm a scalper myself, this is why I like EUR/USD (because of the tight spread).
If you're going for long term (1 hour, 4 hours or more) the spread is not a factor trading any of the majors.
If I wasn't a scalper, I'd like GBP/JPY because of the action.
Trading is boring as hell so at least I'd have some action seing the charts
