WTI oil prices are taking another run at the $80 support this morning, coming under pressure from a renewed rally in the dollar. Prices fluctuated, yesterday, on dollar pressures and strong US economic data. The dollar pulled back after the strong Treasury market auction at 1:00PM, causing losses to be trimmed. Prices had been under pressure, due to the strong Q3 GDP report of 3.5% and the low weekly jobless claims.
