SINGAPORE: US oil may retest a support at $85.73 per barrel, a break below which could trigger a drop to $83.50.

It may extend into a range of $81.26-$83.50, as suggested by the channel and a projection analysis.

The current bounce will not be considered as reversal signal until oil breaks above $90.72.

Immediate resistance is at $89.34, a break above which could lead to a gain into $90.72-$91.84 range.
