Key numbers
over 201 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 0.30. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread currently sits at 3.39 standard deviations above its rolling mean — S is expensive relative to XAUT by the standards of this window.
Reversion is slow: the spread needs roughly 69 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 in the upper part of its range — 100% of the way from the low to the high of the last 201 daily candles.
Frequently asked
How many XAUT is 1 S?
1 S is worth 0.000013932409311982 XAUT at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the S/XAUT range?
Over the last 201 daily candles the ratio traded between 0.000004971068156855 (18.08.2026) and 0.000013932409311982 (12.10.2026).
Are S and XAUT correlated?
The correlation of daily log returns between S and XAUT is 0.30, 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 S/XAUT spread z-score now?
The z-score is 3.39 — the spread is stretched beyond two standard deviations. It measures how far the regression residual log(A) − β·log(B) sits from its rolling mean, in standard deviations.
Is S/XAUT suitable for a pair trade?
Weakly. Correlation is only 0.30, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
