The dollar hit a new seven-month high against the euro on Monday, extending gains after a slew of upbeat data bolstered optimism that the United States is able to fund its current account deficit. Dealers said the greenback was still on a roll after robust U.S. retail sales and employment data lifted the currency through key chart resistance at $1.2730 per euro last week -- its high for the year. The next test will come with U.S. Treasury data at 1300 GMT showing whether the United States attracted enough foreign capital in March to fund its external deficit. "Data on U.S. payrolls and retail sales were better than expected and a lot of real money investors are coming late to the party," said Adam Myers, foreign exchange strategist at Societe Generale.
