Oil prices are mixed in today's session with Brent Crude trading +0.29% at USD78.70 a barrel and West Texas Intermediate Crude losing -0.20% currently quoted at USD74.46. Brent Crude rose after a car bomb exploded in Iraq, OPEC's second largest oil producer. Oil prices are still under pressure amid weakening global demand and the OPEC resisting calls to cut output. The OPEC with its 12 member countries responsible for 40% of world's oil production is scheduled to meet in Vienna on November 27 to discuss 2015 production target.
