The live SPY dealer map
Fear tells you the weather. The SPY dealer positioning map tells you where the tape is pinned and where it breaks — the levels the desks actually trade, live and overlaid on a scalping chart.
SPY is the deepest 0DTE market on the board — tightest spreads, most strikes, and the dealer positioning that moves first. Its gamma exposure tells you whether dealers are damping the tape or amplifying it; its walls tell you where price stalls and where it holds. Here's the public read — the live SPY dealer map is in Analyst.
Public read for SPY — the S&P 500. VIX is ~15-min delayed; the live dealer map (net GEX, flip, walls, expected move) is in NoVo Analyst.

SPY's gamma exposure (GEX) measures how much dealers have to hedge as SPY moves. When net GEX is positive, dealers buy dips and sell rips — moves get damped and price tends to pin toward the gamma flip. When it flips negative, dealers hedge with the move and volatility expands. The call wall is the strike with the heaviest dealer gamma above spot, where upside tends to stall; the put wall is the heaviest below, where downside tends to find a floor; the gamma flip is the line between the two regimes.
On 0DTE, gamma is at its most violent — the same dealer hedging that pins SPY at midday can accelerate it into the close. Trading the level means knowing where the wall is before price gets there, and how much room the day has: the expected move is the ±1σ range the options market is pricing from at-the-money implied vol. NoVo maps net GEX, the flip, both walls and the expected-move band live and overlays them on the chart. The VIX gauge below is the public weather report; the live SPY map is inside NoVo Analyst, and The Journal explains the mechanics in depth.
