Some traders suggested that Monday's wide range reversal to the downside and the prospect that the US economy may be facing a double-dip recession stack in favor of the bears. Expectations for this morning's EIA distillate inventory data are for a weekly build in the range of 1.5 million barrels, compared to an increase of 2.2 million barrels last year.
