My thought is, utilize swap only works best if you're having huge amount, since the interest given by each currency is so small, more over we only take a one day swap interest. unless you hold your position at least a month, in hoping it also has a good profit so you will get double income. As for me who trade with small fund, i think i'm just concentrate on the trading, if I am getting the positive swaps fee then it's my luck. but the swaps is not my main interest.
