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

NEW YORK, Jan 14 (Reuters) - Oil prices rose marginally on Thursday after proposals from the U.S. futures market regulator to limit positions in energy contracts were deemed not as strict as some feared.
The Commodity Futures Trading Commission moved on Thursday to limit the role of big traders in 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 will apply to the four most-traded energy contracts on the two major exchanges.
It remains to be seen if the limits -- which CFTC said would affect only the 10 biggest position holders if implemented immediately -- are sufficient to satisfy lawmakers who have clamored for regulatory action since oil prices surged to a record $147 in 2008.
"The energy markets are breathing a sigh of relief that the CFTC proposals on position limits do not seem as bad as feared," said Phil Flynn, analyst at PFGBest Research in Chicago.
"It looks like the CFTC has backed off from its tough talk earlier and now appears to have a lot of room to grant exemptions."
U.S. crude for February delivery <CLc1> rose 21 cents to $79.86 a barrel by 2:04 p.m. EST (1904 GMT). In London, Brent crude for February <LC0c1> fell 41 cents to $77.90 a barrel ahead of its expiry later in the day.
Crude had earlier fallen 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 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. [
]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 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.
