The time series pattern for the prices and volumes of Brent crude oil sold in the London International Exchange was analyzed using non linear analysis techniques developed for complex systems. The analyses show that the variations in the price index and volume of oil exchanged are not random and differ among them. The variations of prices are asymmetric regarding time, showing higher odds for large decreases compared to increases in price. The price index values show more or less stable short periods in time, suggesting strong historic constrains for prices but not for volumes.
