Key numbers
over 384 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 0.08. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread is at -0.48 standard deviations from its rolling mean, which is effectively at its own norm.
Reversion is slow: the spread needs roughly 64 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 near the bottom of its range — only 10% of the way from the low to the high of the last 384 daily candles.
Frequently asked
How many PROM is 1 APT?
1 APT is worth 0.160636 PROM at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the APT/PROM range?
Over the last 384 daily candles the ratio traded between 0.0697085 (30.08.2026) and 1.02099 (25.03.2026).
Are APT and PROM correlated?
The correlation of daily log returns between APT and PROM 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 APT/PROM spread z-score now?
The z-score is -0.48 — 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 APT/PROM suitable for a pair trade?
Weakly. Correlation is only 0.08, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
