Run the zero-gamma flip recipe
A paid Cookbook of the SPX-style dealer-gamma regime: the zero-gamma flip, positive vs negative gamma, the per-strike GEX profile, and a flip board for the index complex.
Official template: Zero-Gamma Flip — The Dealer Regime Boundary · Updated 2026-09-11
The job
Decide fade-the-edges vs follow-through from a labeled regime boundary, not from a secret “vol trigger.”
What this recipe computes
- The zero-gamma flip: where cumulative GEX crosses zero on the snapshot chain.
- Positive vs negative gamma regime relative to that boundary.
- Per-strike GEX profile and a flip board for the index complex.
What it does not claim
- Crossing the flip is not an entry. It is a regime label.
- Not live HIRO, TRACE, or participant-tagged inventory.
- Snapshot / T+1 chain; 0DTE can change character inside the day.
How to read it
Step 1
Run the flip recipe
Open Zero-Gamma Flip in Cookbooks.
Step 2
Place spot vs the boundary
Above the flip, the map describes a more absorbing regime; below it, a more amplifying one. That is context, not a trade.
Step 3
Validate with tape if you trade it
Use Option Trades or Rank when flow fights the regime story.
Frequently asked questions
- Is the flip the same as SpotGamma’s Vol Trigger?
- No. This recipe reports the zero-gamma crossing on TradingFlow’s snapshot GEX. It does not publish proprietary Vol Trigger or Hedge Wall names.
- Can I trade 0DTE off this flip alone?
- Not from this report. 0DTE can rewrite the day’s character while the map stays snapshot-era. Pair with live tape if you trade same-session options.
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.
- Dealer hedgingDealer hedging is market makers buying or selling the underlying to stay near delta-neutral as price and gamma change.
- 0DTE (zero days to expiration)0DTE options expire the same trading day. Gamma and theta move fastest near the money on that clock.
Related personas
- 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.
- 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.
