The pattern has since broken down, and we can see the 4h Stochastic crossing over to the downside. Prior support sits at 600.86, which we have yet to test from above since we broke above this level several trading sessions ago. A breakdown below this level will spark a larger selloff. Invalidation of shorts occurs when SPY breaks above and turns 603.35 into support. Below that level, the risk-to-reward of puts is better than calls.
From current levels, I see the possibility of a move back into the 560s region and filling the US Election gap. Play it as you see fit.
