NEW YORK, Jan 25 (Reuters) - Oil prices rose slightly on Monday, as the market weighed a weaker dollar and Wall Street's higher open against continuing signs of weak demand.
Still, oil prices were near a one-month low of $74 a barrel after having fallen by almost $10 a barrel over the last two weeks since hitting a 15-month peak of $83.95 on Jan. 11.
U.S. crude for March delivery <CLc1> rose 12 cents to $74.66 a barrel by 12:41 p.m. EST (1741 GMT). The contract fell $1.54 to settle at $74.54 a barrel on Friday, the lowest settlement since Dec. 22, after trading as low as $74.01.
London ICE Brent <LCOc1> rose 36 cents to $73.19.
"Crude and products futures are little changed in New York this morning on moderate overnight volume as the weak dollar supports the markets and prevents further selling," Addison Armstrong, analyst at Tradition Energy in Stamford, Connecticut, said in a research note.
The dollar was broadly weaker on Monday. A weak dollar tends to support commodities priced in dollars as they become cheaper for holders of other currencies. [
