Zero-Gamma Flip — The Dealer Regime Boundary · how the report is assembledConceptual map
  1. 01GEX by strike
  2. 02Cumulative sum
  3. 03Zero-crossing

A modeled regime boundary, not a trading trigger.

Read the output

  1. 01The zero-gamma flip: where cumulative GEX crosses zero on the snapshot chain.
  2. 02Positive vs negative gamma regime relative to that boundary.
  3. 03Per-strike GEX profile and a flip board for the index complex.

Keep in mind

Crossing the flip is not an entry. It is a regime label.

How to read it

From report to evidence

  1. 01

    Run the flip recipe

    Open Zero-Gamma Flip in Cookbooks.

  2. 02

    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.

  3. 03

    Validate with tape if you trade it

    Use Option Trades or Rank when flow fights the regime story.

Method and limitations

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 app template: Zero-Gamma Flip — The Dealer Regime Boundary.

What the report 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.

The flip is the cumulative-GEX zero crossing on the same snapshot chain as Rank’s GEX drawer — a regime boundary, not a live dealer-hedge stream.

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.
