Key numbers
over 373 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 0.36. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread currently sits at -2.01 standard deviations from its rolling mean — API3 is cheap relative to RAD by the standards of this window.
Historically the spread covers half the way back to its mean in about 12 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits mid-range — 24% of the way from the low to the high of the last 373 daily candles.

Are API3 and RAD correlated?
The correlation of daily log returns between API3 and RAD is 0.36, 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 API3/RAD spread z-score now?
The z-score is -2.01 — 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 API3/RAD suitable for a pair trade?
Weakly. Correlation is only 0.36, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
