"The market is supported by continued gains in rival oilseed soyoil," said a Kuala Lumpur-based futures trader, adding that the ringgit's strength capped the vegetable oil's gains.
Palm oil prices are impacted by changes in those of soyoil, as they compete for a share in the global vegetable oil market.
