Does Average True Range Agree on SPY and YM? (1-minute Charts)
Educational reference. Measured from recorded market data through September 4, 2026. Not a forecast.
Average True Range measures how much ground a bar covers — volatility, not direction. This page asks a narrower question than the price comparison: when Average True Range moves on SPDR S&P 500 ETF, does it move the same way on E-mini Dow?
| Bars where Average True Range moved on both | 16,340 |
|---|---|
| … and moved the same direction | 11,398 (69.8%) |
| Price correlation, same period | +0.684 |
Why this is not the same as the price question
Two markets can move together while their momentum, trend strength or volatility do not. A reading that agrees far less than price suggests is exactly where one market is losing steam while the other keeps going — and a reading that agrees more is tracking something shared that direction alone does not capture.
