GDX more upside aheadBut wait until b/o.
High chance it will break out, but whether it can make new highs directly is not that clear. So either:
1. use short term options and take 2/3 profits when close to prior high
2. use long term and hedge with short term put when close to prior high
Depending on your longer term view. The idea is: if prior high was the top, one should see heavy sell off near 44 & 46 (i.e. strong intra-day reversal). Or it should not b/o the triangle at all.
