Likewise, the oil for delivery in December moved down by Rs 1.85, or 0.25 per cent, to Rs 732.20 per 10 kg in 21,400 lots.
Market analysts said offloading of positions by participants due to muted demand in the physical market against ample stocks position on increased supplies from producing belts, mainly led to decline in refined soya oil prices at the futures trade.
