Key numbers
over 206 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 0.01. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread is at -1.19 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 10 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits near the bottom of its range — only 20% of the way from the low to the high of the last 206 daily candles.
Frequently asked
How many NIGHT is 1 U?
1 U is worth 25.9756 NIGHT at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the U/NIGHT range?
Over the last 206 daily candles the ratio traded between 18.1043 (13.03.2026) and 57.467 (18.08.2026).
Are U and NIGHT correlated?
The correlation of daily log returns between U and NIGHT is 0.01, 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 U/NIGHT spread z-score now?
The z-score is -1.19 — 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 U/NIGHT suitable for a pair trade?
Weakly. Correlation is only 0.01, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
