Crude slipped as expectations for more Saudi production and possibly a hike in OPEC output targets weighed on oil prices, while a weak dollar limited losses.
Saudi Arabia is planning to lift oil output sharply in June, whatever policy OPEC adopts at this week's meeting, in an effort to rein in high fuel prices.
Middle East unrest, especially in Yemen, Syria, and the ongoing conflict in Libya also kept oil supported ahead of Wednesday's OPEC meeting.
Now technically market is trading in the range as RSI for 18days is currently indicating 39.06, where as 50DMA is at 4712.92 and crude is trading below the same and getting support at 4378 and below could see a test of 4348 level, And resistance is now likely to be seen at 4443, a move above could see prices testing 4478.
