Key numbers
over 290 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 U and XRP moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.
The spread is at -0.07 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 6 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits mid-range — 64% of the way from the low to the high of the last 290 daily candles.
When this happened before
Divergences over 111 candles: 1. Closed by a return to the norm: 1. The median return took 11 days, the longest one 11 days.
The last closed one ran from 04.09.2026 to 15.09.2026, 11 days: peak z = -2.01, XRP was expensive against U.
For a holder this answers not “what to do” but “how long it usually took”: the median return is 11 days. That is no guarantee — past divergences closed, this one may not.
| Period | Expensive leg | Peak z | Return |
|---|---|---|---|
| 04.09.2026 — 15.09.2026 | XRP | -2.01 | 11 d |
A divergence here is the spread z-score leaving ±2σ; the return is the first value back inside ±0.5σ. Two thresholds rather than one: otherwise chatter right at the border would count as a dozen separate divergences. The first bars of the window are skipped — there z is computed on partial history.
Frequently asked
How many XRP is 1 U?
1 U is worth 0.80133 XRP at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the U/XRP range?
Over the last 290 daily candles the ratio traded between 0.456212 (14.01.2026) and 0.996812 (16.08.2026).
Are U and XRP correlated?
The correlation of daily log returns between U and XRP is -0.21, 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/XRP spread z-score now?
The z-score is -0.07 — 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/XRP 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.
How often do U and XRP diverge?
Over 111 daily candles the spread left ±2σ 1 times. The median return to the norm took 11 days.
