The profitability really depends on the trader and his methods. But I guess you could put it that way if you look at Bill Lipsutchz's hedge fund. Bill is the guy from market wizards who Jack Schwager claimed to be the "Sultan of Currencies". His hedge fund, Hathersage ( go google it) has 2 different sections one which is a long term currency fund, and another which is a short term day trade kind of fund. His results really show the difference in profitability.
