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 0.85. Signals from this pair carry more noise than on a tightly linked one.
The spread is at -0.23 standard deviations from its rolling mean, which is effectively at its own norm.
Historically the spread covers half the way back to its mean in about 22 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits near the bottom of its range — only 0% of the way from the low to the high of the last 330 daily candles.
Frequently asked
How many AR is 1 F?
1 F is worth 0.000915074 AR at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the F/AR range?
Over the last 330 daily candles the ratio traded between 0.000915074 (19.09.2026) and 0.00735309 (25.10.2025).
Are F and AR correlated?
The correlation of daily log returns between F and AR 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 F/AR spread z-score now?
The z-score is -0.23 — 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 F/AR 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 22 days. That is a description of past behaviour, not a forecast or a recommendation.
