Key numbers
over 1316 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 ARB and SOL moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.
The spread is at 1.05 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 407 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 near the bottom of its range — only 1% of the way from the low to the high of the last 1316 daily candles.
When this happened before
Divergences over 1137 candles: 8. Closed by a return to the norm: 7. The median return took 62 days, the longest one 184 days.
The last closed one ran from 03.11.2025 to 06.05.2026, 184 days: peak z = -2.69, SOL was expensive against ARB.
One is running right now: it started on 03.09.2026, has lasted 55 days, peak z = 3.42, ARB was expensive against SOL. It has not returned to the norm yet.
For a holder this answers not “what to do” but “how long it usually took”: the median return is 62 days. That is no guarantee — past divergences closed, this one may not.
| Period | Expensive leg | Peak z | Return |
|---|---|---|---|
| 03.11.2025 — 06.05.2026 | SOL | -2.69 | 184 d |
| 13.08.2025 — 25.09.2025 | ARB | 2.90 | 43 d |
| 09.03.2025 — 10.05.2025 | SOL | -2.51 | 62 d |
| 27.11.2024 — 12.01.2025 | ARB | 2.93 | 46 d |
| 17.06.2024 — 20.10.2024 | SOL | -2.54 | 125 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 SOL is 1 ARB?
1 ARB is worth 0.00169004 SOL at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the ARB/SOL range?
Over the last 1316 daily candles the ratio traded between 0.00083963 (29.08.2026) and 0.0735204 (27.06.2023).
Are ARB and SOL correlated?
The correlation of daily log returns between ARB and SOL is 0.63, 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/SOL spread z-score now?
The z-score is 1.05 — 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/SOL 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 ARB and SOL diverge?
Over 1137 daily candles the spread left ±2σ 8 times. The median return to the norm took 62 days.
