Gold clung to the $1,900 level in choppy trading on Friday, with gains capped by a firm dollar, but bullion remained headed for its biggest weekly rise in eight weeks as U.S. President Donald Trump's COVID-19 positive test hurt risk sentiment.

Spot gold eased 0.2% to $1,900.40 an ounce by 1:42 p.m. EDT (1742 GMT). Prices were set to rise 2.2% this week, heading for the biggest weekly percentage rise since early August.

U.S. gold futures settled down 0.5% at $1,907.60. "The election is 33 days away, there's so much unknown -- will it be a mild case, how will he react to it? So we have flight to safety keeping gold afloat," said Bob Haberkorn, senior market strategist at RJO Futures.

"Traders seem cautious because they're concerned about equity markets selling off." Gold had risen to an over one-week high after Trump said in a tweet that he and his wife Melania had tested positive for the coronavirus, hammering Wall Street.

However the White House reassured Americans that the President was "not incapacitated." Investors also took stock of the last monthly employment report before the Nov. 3 presidential election, which showed U.S. job growth slowed more than expected in September.

"Gold is likely to remain range-bound in the short term. The market will wait through the weekend and look for news," said Tai Wong, head of base and precious metals derivatives trading at BMO.

The dollar too benefited from safe-haven inflows, limiting gold's upside. Focus was also on an elusive U.S. coronavirus relief aid deal. Gold can move back up "if the U.S. congress passes a stimulus bill, that seems to be what this market is hanging on to for now," Haberkorn added.

Elsewhere, silver eased 0.6% to $23.73 an ounce, platinum dropped 2% to $878.47 and palladium was down 0.1% to $2,313.68.
