Gold prices ended the U.S. day session moderately lower Tuesday after hitting a four-month low in mid-morning dealings. Chart-based selling was featured amid a lack of fresh, major fundamental news so far this week. Focus is now squarely on the FOMC meeting that concludes Wednesday afternoon. April Comex gold was last down $6.30 at $1,146.90 an ounce. May Comex silver was last down $0.72 at $15.545 an ounce.
