Key numbers
over 456 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 0.49, with a hedge ratio of 1.23. Signals from this pair carry more noise than on a tightly linked one.
The spread currently sits at -2.57 standard deviations from its rolling mean — ERA is cheap relative to SAND 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 near the bottom of its range — only 4% of the way from the low to the high of the last 456 daily candles.
Frequently asked
How many SAND is 1 ERA?
1 ERA is worth 1.02295 SAND at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the ERA/SAND range?

Are ERA and SAND correlated?
The correlation of daily log returns between ERA and SAND is 0.49, 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 ERA/SAND spread z-score now?
The z-score is -2.57 — 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 ERA/SAND suitable for a pair trade?
The mechanics hold up: correlation is 0.49 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.
