That last bar is an unconfirmed test (upbar to follow for confirmation)
I see some support or accumulation at the previous lows (Jan '15), then a nice up trend.
The gap up in August was a gap over longer term resistance (stale supply), and then the pullback and sideways action, which did not see any follow through on the downbars was promising. However any gap up and pull back raises a concern of supply coming in or distribution of some sort.
But then the recent higher high reduces the chance of ongoing supply, and raises the probabilities for a continuing trend higher.
So now to see what the response to the test is........

cheers
