Key numbers
over 311 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 0.09. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread currently sits at 3.32 standard deviations above its rolling mean — AR is expensive relative to BANK by the standards of this window.
Reversion is slow: the spread needs roughly 41 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 311 daily candles.
Frequently asked
How many BANK is 1 AR?
1 AR is worth 135.932 BANK at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the AR/BANK range?
Over the last 311 daily candles the ratio traded between 3.19328 (27.07.2026) and 135.932 (19.09.2026).
Are AR and BANK correlated?
The correlation of daily log returns between AR and BANK is 0.09, 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 AR/BANK spread z-score now?
The z-score is 3.32 — 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 AR/BANK suitable for a pair trade?
Weakly. Correlation is only 0.09, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
