Expected Behavior

Method

Synthetic GEX Model: Since we don't have live options chains, we model dealer gamma using Black-Scholes gamma at each strike with synthetic OI distribution.

Call GEX: Dealer gamma from calls (positive = dealer hedges by selling into rallies = resistance)
Put GEX: Dealer gamma from puts (negative = dealer hedges by buying dips = support)

Gamma Flip: The price where net GEX crosses zero. Below = negative gamma (amplified moves). Above = positive gamma (damped moves, mean reversion).

Pin Strike: Strike with highest absolute net GEX — price tends to gravitate here near expiry.
