Run the GEX × DEX structural ceiling recipe

What this recipe computes

• Snapshot net GEX and call/put walls with the same kernel as Gamma Structure Map.
• Signed classified DEX = bullish-tagged dex minus bearish-tagged dex (stored dex is unsigned).
• Agree when those two signs match; Disagree when they oppose; Unclear when classified DEX is zero.

What it does not claim

• Agree does not mean a call wall will cap price.
• Classified DEX is not dealer inventory or HIRO/TRACE.
• It is not Wall Break Risk (that recipe labels floor vs accelerant by distance).

How to read it

1. Step 1

   Run the sign-match

   Open Structural Ceiling — GEX × DEX Confirmation in Cookbooks.

2. Step 2

   Read Disagree first

   Opposing signs mean the snapshot book and the day’s classified tape do not rhyme. That is a flag to inspect, not a fade.

3. Step 3

   Split walls, regime, and tape

   Gamma Structure Map still has the strike profile. Wall Break Risk still has distance. Option Trades still has the prints.

Frequently asked questions

Does Agree mean the wall will hold?

No. Agree means snapshot net-GEX sign matches session classified-DEX sign. Walls can still move; 0DTE can still rewrite the tape.

Is signed DEX dealer inventory?

No. Stored dex is an unsigned magnitude. This recipe signs it with sentiment. That is classified flow size, not a dealer book.

Related glossary

• 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.
• Delta exposure (DEX)DEX estimates share-equivalent directional weight of an options trade, roughly delta × size (with the usual multiplier).
• 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.

Related personas

• 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.
• Options Flow for Day TradersDay traders need speed with a filter: see what is printing now, rank what is unusual, then validate structure before risking capital. TradingFlow is built for that same-session loop.
