Key numbers
over 255 daily candles
How each of these is computed: regression spread, hedge ratio, spread z-score, half-life, correlation.
What the numbers say
The fitted hedge ratio is negative: over the window NIL and U moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.
The spread currently sits at 4.41 standard deviations above its rolling mean — NIL is expensive relative to U by the standards of this window.
Historically the spread covers half the way back to its mean in about 17 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits in the upper part of its range — 100% of the way from the low to the high of the last 255 daily candles.
Frequently asked
How many U is 1 NIL?
1 NIL is worth 0.126528 U at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the NIL/U range?
Over the last 255 daily candles the ratio traded between 0.0298391 (01.08.2026) and 0.126528 (24.09.2026).
Are NIL and U correlated?
The correlation of daily log returns between NIL and U is -0.12, 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 NIL/U spread z-score now?
The z-score is 4.41 — 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 NIL/U 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.
