Short 20Y Yield, long 20Y futures: Bias view

Disclaimer 1: This is a bias view. I think that 20Y yield (as well as 10Y) will be going down.
Disclaimer 2: Note that this is the 2nd time this year I am calling for longer duration yields to go down (linked in this analysis).

Analysis portion:
1. H&S formation.
2. Completion of double combination of zig-zag.
