These charts are cool @elementsiz, please keep sharing.
Took me a minute to *think* I understood it... For anyone scratching their head, here is what ChatGTP says:

 Gamma Flip Line (red)

Gamma Flip: 681.74

This is the strike where total gamma shifts negative → positive.

• Below 681.74(red background): Negative gamma zone
  → volatile, bigger swings

• Above 681.74(green background): Positive gamma zone
  → stabilizing hedging flows

  ---

  Green vertical line

  Last Price: 682.04

  Price is just abovethe gamma flip → meaning:

  ? Market is currently in positive gammaterritory
  ?? Not far above the volatility zone — small drop could re-enter negative gamma

  ---

  ? What This Implies for SPY

  Current Position	Interpretation
  Price > Gamma flip	Hedging flows dampen volatility
  Positive gamma overall	Supportivefor gradual upside / mean reversion
  Nearby negative gamma	Dangerif price breaks below ~682

  ---

  ?Trading Interpretation (not advice)

  If SPY stays above ~681.7→
  ? Dips likely get boughtdue to hedging
  ? Upside grind is easier

  If SPY falls below it →
  ?? Market maker hedging flips → volatility increases
  ? Downside moves can accelerate
