The dollar rose against the euro on Friday in choppy trading, boosted by technical factors after the single currency hit key resistance levels, even as the greenback's outlook remained bleak amid cautious signals from the Federal Reserve about further rate hikes.

"It seems like we're getting some model and stop-loss buying on the dollar after the euro hit resistance on the upside," said John Doyle, vice president of dealing and trading at Tempus Inc. in Washington.
