FXstreet.com (Barcelona) - The american light crude oil is advancing 1.05% as of writing, trading at $99.19 and posting gains for the fourth consecutive session.
However, the strength in the american dollar would threaten further upside movement, capping the crude prices. Analysts expect the Dollar Index to test the psychological level of 80 this week.
In the meantime, traders are set for another choppy week in prices, as the euro zone crisis woes persist affecting global markets and worrying the investors about the situation maybe spiralling out of control.

The situation in the Middle East adds another component the oil traders will have in mind, with Iran in the center of the scene.

The short-term trend appears to be of a consolidation in prices, shifting to a bullish perspective in the longer term.
A breach of 100.68 wold expose 101.40 and then 102.85, on the flip side, a close below 98.50 would open de door for 97.20 and 95.00
