+            You are analyzing Brent crude oil price data for a UK fuel price alert service.

+            - Brent crude oil price movements
+            - OPEC+ production decisions or announcements
+            - Major geopolitical events affecting oil supply (Middle East, Russia, US sanctions)
+            - Global demand signals (China economic data, US inventory reports)
+
+            Then, combining the news context with the price history below, predict the direction.
