Key numbers
over 393 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 0.25. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread is at 0.11 standard deviations from its rolling mean, which is effectively at its own norm.
Reversion is slow: the spread needs roughly 76 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 7% of the way from the low to the high of the last 393 daily candles.
When this happened before
Divergences over 214 candles: 1. Closed by a return to the norm: 1. The median return took 184 days, the longest one 184 days.
The last closed one ran from 23.04.2026 to 24.10.2026, 184 days: peak z = -2.89, HUMA was expensive against ERA.
For a holder this answers not “what to do” but “how long it usually took”: the median return is 184 days. That is no guarantee — past divergences closed, this one may not.
| Period | Expensive leg | Peak z | Return |
|---|---|---|---|
| 23.04.2026 — 24.10.2026 | HUMA | -2.89 | 184 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 HUMA is 1 ERA?
1 ERA is worth 3.46308 HUMA at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the ERA/HUMA range?
Over the last 393 daily candles the ratio traded between 1.83347 (05.10.2026) and 26.138 (11.10.2025).
Are ERA and HUMA correlated?
The correlation of daily log returns between ERA and HUMA is 0.25, 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 ERA/HUMA spread z-score now?
The z-score is 0.11 — 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 ERA/HUMA suitable for a pair trade?
Weakly. Correlation is only 0.25, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
How often do ERA and HUMA diverge?
Over 214 daily candles the spread left ±2σ 1 times. The median return to the norm took 184 days.
