Key numbers
over 635 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 0.59, with a hedge ratio of 2.44. Signals from this pair carry more noise than on a tightly linked one.
The spread currently sits at -2.01 standard deviations from its rolling mean — S is cheap relative to ZRO by the standards of this window.
Reversion is slow: the spread needs roughly 59 days to cover half the way back to its mean. A position would have to be held for a long time.
The current ratio sits near the bottom of its range — only 1% of the way from the low to the high of the last 635 daily candles.
Frequently asked
How many ZRO is 1 S?
1 S is worth 0.0227751 ZRO at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.

Are S and ZRO correlated?
The correlation of daily log returns between S and ZRO is 0.59, 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 S/ZRO spread z-score now?
The z-score is -2.01 — 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 S/ZRO suitable for a pair trade?
The mechanics hold up: correlation is 0.59 and the spread historically covers half the way back to its mean in about 59 days. That is a description of past behaviour, not a forecast or a recommendation.
