Key numbers
over 391 daily candles
How each of these is computed: regression spread, hedge ratio, spread z-score, half-life, correlation.
What the numbers say
The legs move together only moderately — correlation of daily log returns is 0.46, with a hedge ratio of 1.04. Signals from this pair carry more noise than on a tightly linked one.
The spread is at -1.91 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 22 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits near the bottom of its range — only 16% of the way from the low to the high of the last 391 daily candles.
When this happened before
Divergences over 212 candles: 1. Closed by a return to the norm: 1. The median return took 44 days, the longest one 44 days.
The last closed one ran from 22.08.2026 to 05.10.2026, 44 days: peak z = 4.49, ARB was expensive against INIT.
For a holder this answers not “what to do” but “how long it usually took”: the median return is 44 days. That is no guarantee — past divergences closed, this one may not.
| Period | Expensive leg | Peak z | Return |
|---|---|---|---|
| 22.08.2026 — 05.10.2026 | ARB | 4.49 | 44 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 INIT is 1 ARB?
1 ARB is worth 1.11275 INIT at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the ARB/INIT range?
Over the last 391 daily candles the ratio traded between 0.75032 (16.02.2026) and 2.95438 (06.09.2026).
Are ARB and INIT correlated?
The correlation of daily log returns between ARB and INIT is 0.46, which counts as a moderate 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 ARB/INIT spread z-score now?
The z-score is -1.91 — 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 ARB/INIT suitable for a pair trade?
The mechanics hold up: correlation is 0.46 and the spread historically covers half the way back to its mean in about 22 days. That is a description of past behaviour, not a forecast or a recommendation.
How often do ARB and INIT diverge?
Over 212 daily candles the spread left ±2σ 1 times. The median return to the norm took 44 days.
