I know their price action is generally identical, 1 ES tick ~ 2.5 SPY ticks.
However, sometimes I see a volume spike in one and not the other. I imagine since ES has the larger dollar-volume liquidity, its volume is more "important."
Right now I trade SPY, but with tick and volume data charted using ES.
Is my reasoning valid? Useless?
Also, since the ticks don't line up evenly, support/resistance may be broken on one and not the other?
