Key numbers

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 0.43, with a hedge ratio of 0.50. Signals from this pair carry more noise than on a tightly linked one.
The spread currently sits at 2.38 standard deviations above its rolling mean — FIL is expensive relative to ERA by the standards of this window.
Historically the spread covers half the way back to its mean in about 16 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits mid-range — 70% of the way from the low to the high of the last 377 daily candles.
Frequently asked
How many ERA is 1 FIL?
1 FIL is worth 13.2864 ERA at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the FIL/ERA range?

Are FIL and ERA correlated?
The correlation of daily log returns between FIL and ERA is 0.43, 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 FIL/ERA spread z-score now?
The z-score is 2.38 — 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 FIL/ERA suitable for a pair trade?
The mechanics hold up: correlation is 0.43 and the spread historically covers half the way back to its mean in about 16 days. That is a description of past behaviour, not a forecast or a recommendation.
