Key numbers
over 359 daily candles
How each of these is computed: regression spread, hedge ratio, spread z-score, half-life, correlation.
What the numbers say
The legs barely move together: correlation of daily log returns is only 0.33. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread currently sits at -2.37 standard deviations from its rolling mean — NOM is cheap relative to ARB by the standards of this window.
Reversion is slow: the spread needs roughly 53 days to cover half the way back to its mean. A position would have to be held for a long time.
The current ratio sits near the bottom of its range — only 4% of the way from the low to the high of the last 359 daily candles.

What is the NOM/ARB spread z-score now?
The z-score is -2.37 — the spread is stretched beyond two standard deviations. It measures how far the regression residual log(A) − β·log(B) sits from its rolling mean, in standard deviations.
Is NOM/ARB suitable for a pair trade?
Weakly. Correlation is only 0.33, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
