The benchmark third-month futures, March, settled flat at 1,415 ringgit ($374) a tonne, after trading between 1,412 and 1,423 ringgit.
At midday, March was up 3 ringgit after technical buying in the morning prompted by Thursday's rise in soyoil but position squaring in the afternoon levelled those gains.
Other traded months closed down 2 ringgit to up 4 ringgit.
Volume was unusually heavy at 4878 lots of 25 tonnes each, more than double Thursday's.
Both palm oil physicals and futures have been hovering above the psychologically important 1,400 ringgit-mark for a week after floods in Malaysia's northern and eastern regions raised concerns about output from oil palm plantations.
A Reuters poll of plantations in the country on Friday, however, found that stocks of palm oil at end-December may be higher than the record 1.6 million tonnes seen at end-November due to weak exports. US soyoil rebounded on Thursday, also on technical buying, after taking sharp losses for two straight days. Soy and palm compete for exports and their prices often move in step.
January soyoil on the Chicago Board of Trade closed up 0.06 cent a lb to close at 20.90 cents. It remained steady in Friday's electronic session, conducted during Asian business hours.
In the physical market for crude palm oil, offers/bids for January closed at 1,410/1,405 ringgit a tonne. Trades were done between 1,410-1,405 ringgit.
