Crude oil futures edged up during the electronic trade on Tuesday recovering part of the previous losses. On Globex, light, sweet crude oil futures for delivery in January added 57 cents to $94.45 during the Asian afternoon trade, gaining 0.6% since opening. The markets were affected by pessimistic economic outlook but the oil is pure exception having the largest number of net long positions thus indicating vulnerability to negative news, said Tim Evans, an energy analyst at Citi Futures Perspective.
