"We're only in the fourth inning of a nine-inning ball game as far as the dollar is concerned," Gartman told CNBC's "Fast Money" on Monday.

"I'll take up [the argument] for crude oil fearing that the sums of available are enormous and the prospects for the exports of U.S. crude are far better," added Gartman.
