Despite the breach of 89.55 resistance on Friday, lack of follow through buying and subsequent retreat from 89.63 suggest consolidation with mild downside bias is in store and weakness towards support at 87.97 cannot be ruled out but below is needed to signal correction from last week's low at 87.10 has ended.  
On the upside, above 89.63 would bring retracement of recent decline to 90.10/20 and then 90.60 before prospect of a pullback.
