KUALA LUMPUR, Feb 10 (Reuters) - Malaysian palm oil futures opened higher on Monday, supported by stronger rival Dalian oils, while traders awaited cargo surveyors' export estimates and the Malaysia Palm Oil Board's (MPOB) supply and demand data for further cues. The benchmark palm oil contract FCPOc3 for April delivery on the Bursa Malaysia Derivatives Exchange gained 25 ringgit, or 0.56%, to 4,529 ringgit ($1,013.65) a metric ton in early trade. The contract has risen for a fourth consecutive session. FUNDAMENTALS Dalian's most-active soyoil contract DBYcv1 rose 0.69%, while its palm oil contract DCPcv1 added 1.34%.

The Malaysian Palm Oil Board is expected to release its January supply and demand data later in the day. Cargo surveyors are expected to release Malaysian palm oil export estimates for February 1-10 later in the day. Oil prices ticked higher even as investors weighed U.S. President Donald Trump's latest tariff threat, this time on all steel and aluminium imports, which could dampen global economic growth and energy demand.
