Does Relative Strength Index Agree on ES and EURUSD? (15-minute Charts)

Educational reference. Measured from recorded market data through September 5, 2026. Not a forecast.

Relative Strength Index measures where price sits within its own recent gains and losses. This page asks a narrower question than the price comparison: when Relative Strength Index moves on E-mini S&P 500, does it move the same way on Euro / U.S. Dollar?

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.
