But, why wait for the range to break on step 3? Having a look just at when the 2.0 drifts through - the ones that get to around 2.06, 2.08, 2.10 are in that "Goldilocks zone" of confirmation, for a further drift. I'd have preempted ya on that one A beautiful parabola (3.5mth sample size of 2.0 drifts)
