Key numbers
over 670 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 2.06 standard deviations above its rolling mean — ORCA is expensive relative to ACE by the standards of this window.
Historically the spread covers half the way back to its mean in about 17 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits mid-range — 74% of the way from the low to the high of the last 670 daily candles.
Frequently asked
How many ACE is 1 ORCA?
1 ORCA is worth 15.0765 ACE at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the ORCA/ACE range?
Over the last 670 daily candles the ratio traded between 1.68605 (21.12.2024) and 19.8525 (02.05.2026).
Are ORCA and ACE correlated?
The correlation of daily log returns between ORCA and ACE 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 ORCA/ACE spread z-score now?
The z-score is 2.06 — 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 ORCA/ACE 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.
