Key numbers
over 330 daily candles
How each of these is computed: regression spread, hedge ratio, spread z-score, half-life, correlation.
What the numbers say
The legs move together only moderately — correlation of daily log returns is 0.56, with a hedge ratio of 0.86. Signals from this pair carry more noise than on a tightly linked one.
The spread is at -1.43 standard deviations from its rolling mean: away from the norm, but not far enough to call it stretched.
Historically the spread covers half the way back to its mean in about 29 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits near the bottom of its range — only 5% of the way from the low to the high of the last 330 daily candles.

Are F and ARB correlated?

What is the F/ARB spread z-score now?
The z-score is -1.43 — 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 F/ARB suitable for a pair trade?
The mechanics hold up: correlation is 0.56 and the spread historically covers half the way back to its mean in about 29 days. That is a description of past behaviour, not a forecast or a recommendation.
