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 0.65, with a hedge ratio of 0.93. Signals from this pair carry more noise than on a tightly linked one.
The spread is at -0.32 standard deviations from its rolling mean, which is effectively at its own norm.
Reversion is slow: the spread needs roughly 30 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 mid-range — 26% of the way from the low to the high of the last 988 daily candles.
