Key numbers
over 235 daily candles
How each of these is computed: regression spread, hedge ratio, spread z-score, half-life, correlation.
What the numbers say
The fitted hedge ratio is negative: over the window RAY and RLUSD moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.
The spread currently sits at 3.15 standard deviations above its rolling mean — RAY is expensive relative to RLUSD by the standards of this window.
Reversion is slow: the spread needs roughly 74 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 — 73% of the way from the low to the high of the last 235 daily candles.
Frequently asked
How many RLUSD is 1 RAY?
1 RAY is worth 1.45756 RLUSD at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.

Are RAY and RLUSD correlated?
The correlation of daily log returns between RAY and RLUSD is -0.07, 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 RAY/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 RAY/RLUSD suitable for a pair trade?
No. The fitted hedge ratio is negative, meaning the legs moved in opposite directions over the window — the market-neutral construction that pair trading relies on does not hold here.
