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 0.16. A spread built on such a weak link reverts by coincidence rather than by mechanism.

The spread is at 1.30 standard deviations from its rolling mean: away from the norm, but not far enough to call it stretched.

Reversion is slow: the spread needs roughly 47 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 — 67% of the way from the low to the high of the last 384 daily candles.

Frequently asked

How many XRP is 1 PROM?

1 PROM is worth 3.8984 XRP at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.

What is the PROM/XRP range?

Over the last 384 daily candles the ratio traded between 0.70978 (10.03.2026) and 5.50401 (30.08.2026).

Are PROM and XRP correlated?

The correlation of daily log returns between PROM and XRP is 0.16, 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 PROM/XRP spread z-score now?

The z-score is 1.30 — 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 PROM/XRP suitable for a pair trade?

Weakly. Correlation is only 0.16, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
