across the board," said Carsten Menke, analyst at Julius Baer in
Zurich. He attributed the move in the greenback to a combination
of events in the United States and Europe.
Spot gold was up 0.6 percent at $1,237.85 an ounce by
3:30 p.m. EDT (1930 GMT), after rising to $1,239.10, the highest

The dollar index slipped to the weakest in more than
six months after two U.S. officials said President Donald Trump

high at $942, a two-week high.
A bullish signal for platinum has appeared in charts, said
Stéphanie Aymes, head of technical analysis at Societe Generale.
"Short term, platinum looks headed for $953, the trend line
resistance and the 61.8 percent retracement of the last bout of
down move, and $991," she said in a note, adding that further
targets would be $1,046 and $1,080.
