Key numbers
over 271 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 OP and U moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.
The spread is at 1.36 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 21 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits near the bottom of its range — only 19% of the way from the low to the high of the last 271 daily candles.
Frequently asked
How many U is 1 OP?
1 OP is worth 0.138045 U at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the OP/U range?
Over the last 271 daily candles the ratio traded between 0.0844578 (18.08.2026) and 0.373709 (13.01.2026).
Are OP and U correlated?
The correlation of daily log returns between OP and U is -0.04, 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 OP/U spread z-score now?
The z-score is 1.36 — 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 OP/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.
