if you trade here, definitely utilize swaps. They are one of the better things about xs.com (other 2 being the safety and the liquidity, but if you're trading with just $5k-$20k, the liquidity is not a concern either way).
Swaps are very good and beneficial here, also I guess if you're really big and can utilize the millions in insurance they give, but for me even 20k euros would be ok, lol.
