Key numbers
over 257 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 RARE and U moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.
The spread is at 0.43 standard deviations from its rolling mean, which is effectively at its own norm.
Historically the spread covers half the way back to its mean in about 18 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits mid-range — 54% of the way from the low to the high of the last 257 daily candles.
Frequently asked
How many U is 1 RARE?
1 RARE is worth 0.0233547 U at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.

Are RARE and U correlated?
The correlation of daily log returns between RARE and U is -0.08, 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 RARE/U spread z-score now?
The z-score is 0.43 — 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 RARE/U 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.
