E-mini S&P 500 and SPDR S&P 500 ETF are often assumed to move together. This measures it against 2,797 time-aligned 1-minute bars over the last 45 days — no opinion, just what the two actually did.
| Bars where both moved | 2,386 |
|---|---|
| … and moved the same direction | 2,153 (90.2%) |
| Correlation of bar-to-bar changes | +0.890 |
At 90.2% agreement and a correlation of +0.890, these two have a strong tendency to move together on this timeframe.

Prices moving together does not mean everything else does. The indicator pages below measure each reading separately — and momentum, trend strength and volatility frequently disagree even when price does not.

Every 1-minute bar recorded for both instruments in the last 45 days was aligned by timestamp. Bars where either did not move are excluded from the direction figure, since a flat bar agrees with nothing. Correlation is measured on bar-to-bar changes, not on price levels — two markets can both drift upward for unrelated reasons, and correlating levels would call that a relationship.
