Key numbers
over 356 daily candles
How each of these is computed: regression spread, hedge ratio, spread z-score, half-life, correlation.
What the numbers say
The legs move closely together — correlation of daily log returns is 0.81. The fitted hedge ratio is 1.00, meaning roughly 1.00 units of FIL exposure balance one unit of AR.
The spread currently sits at 2.84 standard deviations above its rolling mean — AR is expensive relative to FIL by the standards of this window.
Reversion is slow: the spread needs roughly 39 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 356 daily candles.
Frequently asked
How many FIL is 1 AR?
1 AR is worth 4.19631 FIL at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the AR/FIL range?
Over the last 356 daily candles the ratio traded between 1.59729 (01.03.2026) and 4.19631 (19.09.2026).
Are AR and FIL correlated?
The correlation of daily log returns between AR and FIL is 0.81, which counts as a strong 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/FIL spread z-score now?
The z-score is 2.84 — 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/FIL suitable for a pair trade?
The mechanics hold up: correlation is 0.81 and the spread historically covers half the way back to its mean in about 39 days. That is a description of past behaviour, not a forecast or a recommendation.
