* U.S. retail sales down, jobless claims up
* CFTC proposes energy trader position limits
* Prices in range between $75 and $85 a barrel (Updates prices, adds detail on CFTC proposals)

NEW YORK, Jan 14 (Reuters) - Oil prices slipped marginally on Thursday as weak U.S. economic signals spurred fears of a sluggish rebound in demand in the world's largest energy consumer.
U.S. retail sales fell 0.3 percent last month, the first decline in three months, according to the Commerce Department, while Labor Department data showed more people sought jobless benefits last week. [
]U.S. crude for February delivery <CLc1> fell 6 cents to $79.59 a barrel by 1:25 p.m. EST (1825 GMT), after touching a 2010 low of $78.37 on Wednesday. In London, Brent crude for February <LC0c1> fell 38 cents to $77.93 a barrel ahead of its expiry later in the day.
U.S. crude oil stocks rose by a larger-than-expected 3.7 million barrels last week, Energy Information Administration data showed on Wednesday. And, while heating oil stocks fell by 1.1 million barrels, stocks for the broader category known as distillates still rose by 1.4 million barrels. [
]"Crude futures are down in follow-through selling after yesterday's EIA data showed very large builds in petroleum inventories. Data on retail sales have been disappointing also," said Brad Samples, analyst at Summit Energy in Louisville, Kentucky.
U.S. economic activity is now at a low level but is showing signs of modest improvement, the Federal Reserve said on Wednesday, in remarks seen as reinforcing the prevailing view that oil demand will grow in 2010. [
]Early this month, oil prices rallied to 15-month highs near $84 a barrel as freezing weather across much of the Northern Hemisphere boosted heating demand. Prices then fell, partly on a surprise jump in U.S. distillate stocks, including heating oil, and a rise in crude oil inventories.
Some traders chose to take advantage of Wednesday's price dip by covering short positions and this also helped boost prices back to near $80 a barrel on Thursday, analysts said.
"Prices are moving in a $75-$85 range. It was very good timing to buy back the market," said Ken Hasegawa, a commodity derivatives manager at brokerage Newedge in Japan.
PRICES UNMOVED BY CFTC
The top U.S. futures market regulator moved on Thursday to limit the role of big traders in once high-flying energy markets, unveiling proposals to put a hard cap on the size of positions that dealers can hold, but offering a limited exemption for big financial hedgers. [
]The long-awaited proposals, part of the Obama administration's push to overhaul financial markets, will apply to the four most-traded energy contracts on the two major exchanges.
But it remains to be seen if the limits -- which CFTC said would affect only the 10 biggest position holders, if implemented today -- are sufficient to satisfy lawmakers who have clamored for regulatory action since oil prices surged to a record $147 in 2008.
