With oil prices having fallen around -25% from the September high, a correction higher may be due.
And as prices failed to hold beneath $70, Wednesday's bullish hammer (which is also a higher low) has caught out eye). The hammer was coupled with above-average volume to suggest demand around $75, and the initial break below $70 was seen on strong negative delta (more sellers than buyers) which means the subsequent move higher likely forced them to cover and reconsider their direction.
A move towards $75 could help improve the reward to risk ration for an anticipate move to $80, a break above which brings $82 into focus just beneath the January and April highs.
