Connecting…Calculation methodology
Gamma engine. Dollar gamma, flip level, walls and concentration come from the same Barchart chain aggregation as the Gamma Hedge monitor: GEX = gamma × contracts × 100 × spot² × 0.01 per strike, summed across the nearest expirations plus the next monthly OPEX. The nearest repriced zero-GEX crossing is refined with a bounded Newton-Raphson solve.
Expected move. 0/1 DTE 1σ range = spot × ATM IV × √(DTE/365), using the nearest-expiry strike IV closest to spot. Same-day chains use a one-calendar-day floor so the risk band remains usable through expiration day.
Structure selection. Long-gamma regimes get iron condors with shorts at spot ± 0.75× expected move and wings at ± 1.5× expected move, snapped to listed strikes; near/below-flip regimes get wall-breakout longs. Win probability is the lognormal P(put short < S_T < call short) at 1 DTE.
Charm. Dealer delta decay per day = BS charm × open interest × 100 × spot on the nearest expiration; OTM strikes dominate the afternoon unwind (2:00–3:45 PM ET) as their delta bleeds toward 0/±1.
