$710 is the line in the sand for SPY

By Charlie Zhang | Chart Watch

$710 is the line in the sand for SPY. The chatter on Reddit has shifted from geopolitical noise to a specific, technical number. Friday’s close sliced right through it, and now the market is holding its breath at $705. This isn't about Iran or earnings anymore; it's about a gamma flip.

When SPY closed above $710, market makers (the "dealers") were structurally long gamma. That meant they were pinning the price, fading big rips and buying dips to stay neutral. It was a damper on volatility. But a close below $710 changes the game. Now, those same dealers are short gamma. They have to chase price moves to hedge, which can make both rallies and sell-offs sharper and faster. The damper is off. The crowd is laser-focused on this level, with one detailed post laying out the entire ladder: a $720 call wall acting as a hard cap above, and a $700 put wall acting as a magnet below.

The pattern here is a classic regime shift. We’ve broken a key support level that also served as a volatility control mechanism. The market is telling us that the automatic, stabilizing bids that were propping up the relentless grind higher have been removed. Now, price discovery gets messy. Retail traders are watching this level closely, with many positioning for a test of $700. The fear isn't about war; it's about getting caught on the wrong side of a dealer-driven move.

The Setup

Above $710, the path opens for a reclaim rally toward $715 and potentially $720. But it needs to happen with volume—a weak bounce won't flip the dealers back to long gamma.

Below $707, and especially on a break of $705, the magnet is $700. If that level breaks on above-average volume, the next stop is $693. In a short gamma regime, moves feed on themselves.

Watch the first 15 minutes Monday. A failure to reclaim $707 points to bears in control. A swift push back above $710 signals the bulls have wrestled back the narrative. Anything in between means chop—and patience.
