CHICAGO, Nov. 19 (Xinhua) -- Gold futures on the COMEX division of the New York Mercantile Exchange continued to rise on Monday as safe-haven appeal was growing amid geopolitical and trade uncertainties.

The most active gold contract for December delivery was up 2.3 dollars, or 0.19 percent, to settle at 1,225.3 dollars per ounce, booking a fourth straight day of gains.

Uncertainties surrounding Britain's planned exit from the European Union and future Sino-U.S. trade relations supported gold, viewed as a safe-haven asset, said analysts.

The U.S. dollar index, a gauge of the greenback against a basket of other major currencies, fell 0.27 percent to 96.18 as of 1817 GMT.

Gold and the dollar usually move in opposite directions. When the dollar goes down, gold futures will rise as gold, measured by the dollar, becomes less expensive for investors using other currencies.

Analysts noted that the fall of equities also gave support to gold futures, as Dow Jones Industrial Average fell by 449.96 points, or 1.77 percent as of 1827 GMT. The S&P 500 and Nasdaq followed Dow's sharp fall.

As for other precious metals, silver for December delivery went up 2.1 cents, or 0.15 percent, to close at 14.403 dollars per ounce. Platinum for January 2019 delivery was up 11.00 dollars, or 1.3 percent, to settle at 857.60 dollars per ounce. Enditem
