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 legs barely move together: correlation of daily log returns is only 0.27. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread is at 0.62 standard deviations from its rolling mean, which is effectively at its own norm.
Reversion is slow: the spread needs roughly 53 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 — 22% of the way from the low to the high of the last 272 daily candles.
When this happened before
Divergences over 93 candles: 2. Closed by a return to the norm: 1. The median return took 21 days, the longest one 21 days.
The last closed one ran from 31.07.2026 to 21.08.2026, 21 days: peak z = -2.49, ZAMA was expensive against STX.
One is running right now: it started on 14.10.2026, has lasted 17 days, peak z = 2.06, STX was expensive against ZAMA. 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 21 days. That is no guarantee — past divergences closed, this one may not.
| Period | Expensive leg | Peak z | Return |
|---|---|---|---|
| 31.07.2026 — 21.08.2026 | ZAMA | -2.49 | 21 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 ZAMA is 1 STX?
1 STX is worth 4.69662 ZAMA at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the STX/ZAMA range?
Over the last 272 daily candles the ratio traded between 2.12204 (29.07.2026) and 13.8384 (10.03.2026).
Are STX and ZAMA correlated?
The correlation of daily log returns between STX and ZAMA is 0.27, 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 STX/ZAMA spread z-score now?
The z-score is 0.62 — 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 STX/ZAMA suitable for a pair trade?
Weakly. Correlation is only 0.27, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
How often do STX and ZAMA diverge?
Over 93 daily candles the spread left ±2σ 2 times. The median return to the norm took 21 days.
