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 0.63, with a hedge ratio of 0.46. Signals from this pair carry more noise than on a tightly linked one.
The spread is at -0.91 standard deviations from its rolling mean, which is effectively at its own norm.
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 0% of the way from the low to the high of the last 374 daily candles.
