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 0.30. A spread built on such a weak link reverts by coincidence rather than by mechanism.

The spread is at -0.41 standard deviations from its rolling mean, which is effectively at its own norm.

Historically the spread covers half the way back to its mean in about 21 days, so a divergence here tends to resolve within weeks rather than months.

The current ratio sits mid-range — 37% of the way from the low to the high of the last 373 daily candles.

What is the API3/ACE spread z-score now?

The z-score is -0.41 — 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 API3/ACE suitable for a pair trade?

Weakly. Correlation is only 0.30, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
