Key numbers
over 350 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 0.54, with a hedge ratio of 0.92. Signals from this pair carry more noise than on a tightly linked one.
The spread is at 0.58 standard deviations from its rolling mean, which is effectively at its own norm.
Reversion is slow: the spread needs roughly 48 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 11% of the way from the low to the high of the last 350 daily candles.
