Key numbers
over 330 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 together only moderately — correlation of daily log returns is 0.49, with a hedge ratio of 0.58. Signals from this pair carry more noise than on a tightly linked one.
The spread currently sits at 2.19 standard deviations above its rolling mean — AR is expensive relative to F by the standards of this window.
Reversion is slow: the spread needs roughly 32 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 330 daily candles.
Frequently asked
How many F is 1 AR?
1 AR is worth 1120.82 F at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the AR/F range?
Over the last 330 daily candles the ratio traded between 135.997 (25.10.2025) and 1120.82 (19.09.2026).
Are AR and F correlated?
The correlation of daily log returns between AR and F is 0.49, which counts as a moderate 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/F spread z-score now?
The z-score is 2.19 — 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/F suitable for a pair trade?
The mechanics hold up: correlation is 0.49 and the spread historically covers half the way back to its mean in about 32 days. That is a description of past behaviour, not a forecast or a recommendation.
