Oil has now approached the marginal resistance zone 77.41-77.97, as shown in the previous analysis. Large point volumes have appeared in the zone and may mean fixation of purchases and the beginning of accumulation of corrective sales. The question is whether the pullback will be and how deep it will be. In general, I expect an approach around 1/2 of the margin and then up again from there. That's why yesterday at 77.40 I closed 50% of buys and I'm still in the waiting mode. Oil after filling volumes likes to make gains and then go into a reversal.
