Key numbers
over 230 daily candles
How each of these is computed: regression spread, hedge ratio, spread z-score, half-life, correlation.
What the numbers say
The fitted hedge ratio is negative: over the window ZAMA and ARB moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.
The spread is at 1.95 standard deviations from its rolling mean: away from the norm, but not far enough to call it stretched.
Reversion is slow: the spread needs roughly 90 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 mid-range — 27% of the way from the low to the high of the last 230 daily candles.

Are ZAMA and ARB correlated?
The correlation of daily log returns between ZAMA and ARB is 0.30, which counts as a weak link. Log returns are used rather than prices: two rising assets correlate almost by default, joint day-to-day movement is what matters.
What is the ZAMA/ARB spread z-score now?
The z-score is 1.95 — the spread is within its usual range. It measures how far the regression residual log(A) − β·log(B) sits from its rolling mean, in standard deviations.
Is ZAMA/ARB suitable for a pair trade?
No. The fitted hedge ratio is negative, meaning the legs moved in opposite directions over the window — the market-neutral construction that pair trading relies on does not hold here.
