In line with weak international trend, gold futures were trading lower by Rs 150 at Rs 31,178 per 10 gram as speculators trimmed their positions.
Similarly, the metal for delivery in far-month December was trading down Rs 141, or 0.45 per cent, to Rs 31,310 per 10 gram in 176 lots.
The fall in gold futures was mostly in step with a weak trend overseas after its biggest weekly advance in two months, as the dollar erased losses, dimming the metal s appeal as an alternative investment, analysts said.
Meanwhile, gold prices fell 0.21 per cent, to USD 1,334.70 an ounce in Singapore today after a 2.1 per cent gain last week, the most since the period to July 29.
