* Palm falls after three earlier winning sessions * Stronger ringgit also weighs on palm - trader * Official Malaysia data release scheduled for April 10 By Emily Chow KUALA LUMPUR, April 9 (Reuters) - Malaysian palm oil futures fell on profit-taking on Wednesday after three sessions of gains while a stronger ringgit and overnight losses in U.S. soyoil on the Chicago Board of Trade also weighed. The benchmark palm oil contract for June delivery on the Bursa Malaysia Derivatives Exchange fell 1 percent to 2,480 ringgit ($642.32) a tonne at the midday break, its sharpest fall in three weeks. Palm had hit a five-week high in the previous session after Malaysia announced it would extend tax exemptions on crude palm oil (CPO) exports to a fourth straight month in April. Trading volumes stood at 13,422 lots of 25 tonnes each at noon. "We're seeing some profit-taking after palm's last session, which was overdone on the upside, and ahead of the Malaysian Palm Oil Board report due tomorrow," said a Kuala Lumpur-based futures trader. The Malaysian industry regulator is scheduled to release official data on palm oil's March stockpiles, production and exports after 0430 GMT on Tuesday. End-stocks in Malaysia are forecast to have declined 8.6 percent from February to 2.27 million tonnes, while exports are seen rising to 19.3 percent on-month to 1.57 million tonnes, according to a Reuters poll. Meanwhile, production is seen up 11.3 percent to 1.49 million tonnes in March. The trader also added that weaker overnight soyoil on the Chicago Board of Trade and a stronger ringgit also weakened palm oil prices on Monday. A stronger ringgit, palm's currency of trade, typically makes the edible oil more expensive for foreign buyers. The ringgit slightly strengthened against the dollar in early trade on Monday, rising 0.2 percent to 3.8610 per dollar around noon. In related oils, the Chicago Board of Trade's May soybean oil contract declined 0.8 percent on Friday, but was last up 0.3 percent on Monday. The May soybean oil on China's Dalian Commodity Exchange jumped 2.1 percent, while the Dalian May palm oil contract rose 1.4 percent. Palm oil prices are impacted by movements in rival edible oils as they compete for a share in the global vegetable oils market.
