Key numbers
over 367 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 0.39. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread is at 0.38 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 27 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits near the bottom of its range — only 11% of the way from the low to the high of the last 367 daily candles.
Frequently asked
How many ARK is 1 ZRO?
1 ZRO is worth 4.71827 ARK at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.

Are ZRO and ARK correlated?
The correlation of daily log returns between ZRO and ARK is 0.39, 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 ZRO/ARK spread z-score now?
The z-score is 0.38 — 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 ZRO/ARK suitable for a pair trade?
Weakly. Correlation is only 0.39, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
