Gold swung between gains and losses on Wednesday and traded close to the strongest level in more-than-a-three-week period amid speculation that Fed may wait with scaling back its stimulus program until the next year as payrolls rose less than forecast. Bullion for settlement in October was at $1,340.10 an ounce as of 7:57 a.m. Singapore time after it touched the highest level since September 30 at $1,344.85 yesterday.
