Thx for sharing OP.Just something i've noticed with intermarket analysis.
Two risk assets like those have a hard time moving together. Not to say they can't but if you already have a strong period of moving together so now it makes sense to "diverge". We'll see.
PS. It requires a good amount of discretion to trade like that.
If the bet is that they will diverge, then why short both? Is it because one will fall at a different rate than the other (ie. They will diverge) so you pocket the spread?
