What the numbers say

The legs barely move together: correlation of daily log returns is only -0.10. A spread built on such a weak link reverts by coincidence rather than by mechanism.

The spread currently sits at 3.15 standard deviations above its rolling mean — ORCA is expensive relative to RLUSD by the standards of this window.

Reversion is slow: the spread needs roughly 48 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 258 daily candles.

Frequently asked

How many RLUSD is 1 ORCA?

1 ORCA is worth 2.55123 RLUSD at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.

What is the ORCA/RLUSD range?

Over the last 258 daily candles the ratio traded between 0.765311 (11.02.2026) and 2.55123 (06.10.2026).

Are ORCA and RLUSD correlated?

The correlation of daily log returns between ORCA and RLUSD is -0.10, 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/RLUSD spread z-score now?

The z-score is 3.15 — 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/RLUSD suitable for a pair trade?

Weakly. Correlation is only -0.10, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
