Crude oil futures were trading higher Monday morning, but several factors suggest that a further correction is possible after sharp falls last week.

At 0947 GMT, the April Brent contract on London's ICE futures exchange was at $114.95 a barrel, up 85 cents, or 0.7%. Nymex light, sweet crude for April delivery was up 53 cents, or 0.6%, at $93.66 a barrel.

The April contract opened last week at $117.81 a barrel but fell to a low of $113.32 a barrel Thursday, before rising somewhat to settle at a weekly loss of 3.1%.

"The recent price drop came on the back of what we would see as a deflation of a rally that was driven more by speculative forces than by market fundamentals themselves," wrote analysts from JBC Energy in a note.

Increased volatility in both London and New York crude futures markets suggests that both contracts are heading towards a further downward correction, according to the Schork Report.

"[I]f you buy into the notion that implied volatility falls in bullish markets (on the assumption bull markets are less risky than bear markets) than the current run in option valuations is a concern...bottom line, just like we said for New York, the market in London looks vulnerable to corrective weakness," the report said.

Implied volatility--which measures the relationship between the underlying price of a commodity and an option to purchase it--rose by 35% last week. Schork said that market sentiment was still bullish, however, and that any change to that status was awaiting confirmation from this week's price movements.

In the U.S., money managers have cut their net long positions in WTI crude, implying that they also believe price fall to be on the way. Investors take long positions, buying into a commodity, when they expect its price to go up and are more likely to take short positions if they believe that the price will fall.

Equivalent data for U.K. managers is due later Monday.

A boost to the markets is possible on Tuesday, however, depending on the outcome of a scheduled meeting between Iran and the P5+1 countries--China, France, Russia, the U.K., the U.S and Germany. The meeting, to be held in Kazakhstan, will hope to make progress on negotiations over sanctions placed on Iran's oil exports.

The sanctions, which were put in place as a check on Iran's nuclear program, have cut the country's production to their lowest level in 30 years, according to the International Energy Agency.

At 0948 GMT, the ICE's gasoil contract for March delivery was up $10.75, or 1.1%, at $988.50 per metric ton, while Nymex gasoline for March delivery was up 439 points, or 1.4%, at $3.1235 per gallon.
