Run the gamma structure map recipe
A paid Cookbook of prior-close, convention-based GEX structure for the index complex and active single names: concentration strikes, the highest net-GEX strike, and regime context. It does not claim support, targets, pins, or forecasts.

The job
Print today’s walls and magnet from the chain snapshot, then validate with tape if you trade them.
What this recipe computes
- Call and put concentration strikes (walls) and a gamma magnet from the latest chain snapshot.
- Highest net-GEX strike and a simplified call(+)/put(−) regime read.
- Index complex (SPX/SPY/QQQ and related roots) plus active single names, with DTE windows documented in the recipe.
What it does not claim
- Levels are descriptive. They are not support, resistance, targets, or pins.
- GEX is snapshot / prior-close (T+1 style), not live dealer inventory or HIRO/TRACE.
- It does not overlay ES/NQ futures options or TradingView.
How to read it
Step 1
Run the structure map
Open Gamma Structure Map in Cookbooks for the latest chain snapshot.
Step 2
Read walls as concentrations
Note call/put clusters and the magnet relative to spot. Do not treat a bar as a guaranteed hold.
Step 3
Check flow at the level
If you act, inspect Rank or Option Trades for session flow at those strikes. The recipe is the map, not the tape.
Frequently asked questions
- Is this live GEX?
- No. The map uses the latest option-chain snapshot (prior close / T+1 style) with a live spot overlay where the product shows one. It is not a tick-by-tick dealer book.
- Will the call wall hold?
- The recipe does not say. Walls are concentration strikes. Flow, expiry, and regime can move them. Use the report as structure, then the tape.
Related glossary
- Call wallA call wall is the strike above spot with the densest call open interest or call-side gamma. Traders often treat it as resistance when dealers hedge.
- Put wallA put wall is the strike below spot with the densest put open interest or put-side gamma. Traders often treat it as support when dealers hedge.
- Gamma exposure (GEX)GEX estimates aggregate dealer gamma from listed options. Positive gamma tends to dampen moves; negative gamma tends to amplify them. Option gamma is the building block; extreme short-gamma feedback is covered under gamma squeeze.
- Dealer hedgingDealer hedging is market makers buying or selling the underlying to stay near delta-neutral as price and gamma change.
Related personas
- Call Walls for Index TradersIndex sessions often trade as a conversation between spot and open-interest walls. Call walls frame upside resistance; they need flow confirmation before you treat them as hard stops.
- GEX and Option Flow for Index TradersIndex traders care about session character: where call/put walls sit, whether gamma is dampening or amplifying, and whether premium is chasing or fading the move.
- GEX for Day TradersDay traders should not treat GEX as an entry trigger. Use it for dampened vs amplified expectations, then time with ranked flow and walls.
