Key numbers
over 272 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 ZK and U moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.
The spread is at 1.17 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 33 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 272 daily candles.
Frequently asked
How many U is 1 ZK?
1 ZK is worth 0.0156969 U at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the ZK/U range?
Over the last 272 daily candles the ratio traded between 0.00745627 (13.08.2026) and 0.0380524 (14.01.2026).
Are ZK and U correlated?
The correlation of daily log returns between ZK and U is -0.10, 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 ZK/U spread z-score now?
The z-score is 1.17 — 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 ZK/U 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.
