What the numbers say

The fitted hedge ratio is negative: over the window U and QI moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.

The spread is at -1.04 standard deviations from its rolling mean: away from the norm, but not far enough to call it stretched.

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 256 daily candles.

Frequently asked

How many QI is 1 U?

1 U is worth 279.95 QI at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.

What is the U/QI range?

Over the last 256 daily candles the ratio traded between 277.833 (14.01.2026) and 886.195 (30.06.2026).

Are U and QI correlated?

The correlation of daily log returns between U and QI is -0.14, 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 U/QI spread z-score now?

The z-score is -1.04 — 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 U/QI suitable for a pair trade?

No. The fitted hedge ratio is negative, meaning the legs moved in opposite directions over the window — the market-neutral construction that pair trading relies on does not hold here.
