Key numbers
over 378 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 0.74. The fitted hedge ratio is 0.91, meaning roughly 0.91 units of S exposure balance one unit of APT.
The spread currently sits at -2.05 standard deviations from its rolling mean — APT is cheap relative to S by the standards of this window.
Historically the spread covers half the way back to its mean in about 8 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 378 daily candles.
Frequently asked
How many S is 1 APT?
1 APT is worth 14.1147 S at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the APT/S range?
Over the last 378 daily candles the ratio traded between 14.1147 (11.10.2026) and 29.7348 (25.06.2026).
Are APT and S correlated?
The correlation of daily log returns between APT and S is 0.74, 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 APT/S spread z-score now?
The z-score is -2.05 — 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 APT/S suitable for a pair trade?
The mechanics hold up: correlation is 0.74 and the spread historically covers half the way back to its mean in about 8 days. That is a description of past behaviour, not a forecast or a recommendation.
