MPC
Marathon Petroleum CorporationPrices and gamma are point-in-time snapshots taken at the time shown. Dealer positioning is an assumption, not an observable: open interest shows that a contract exists, never which side a dealer holds. How dealer gamma is computed.

MPC DEALER GAMMA BY STRIKE
Part of the SquawkFlow GEX Calculator: gamma by strike for any US stock. Compare with SPX GEX.
Net gamma exposure at each strike near MPC's spot price, signed from the dealer perspective, calls positive, puts negative. Green strikes are where hedging tends to dampen moves; red is where it tends to amplify them. Dealer positioning is an assumption rather than an observable, so treat these as a map of where hedging pressure concentrates, not a forecast.
Unit: USD of dealer gamma per 1 percent move in spot. A window of the MPC option chain, not the whole book: the 30 strikes nearest spot out of 40 seen, 842 contract rows spanning 12 expirations. Gamma is taken as the chain publishes it per contract; nothing here is re-priced. Crossed with the open interest carried on that chain.
New to these levels? Start with the call wall and put wall, or the zero gamma level where the sign of dealer hedging flips.

ABOUT MPC
Marathon Petroleum is the largest petroleum refiner in the United States, operating 13 refineries with approximately 3 million barrels per day of crude oil capacity. It also owns a majority stake in MPLX, a midstream MLP, and operates the Speedway-legacy retail network (sold to 7-Eleven but retained fuel supply contracts).
WHY TRACK MPC ON SQUAWKFLOW
MPC options flow directly reflects refining margin (crack spread) expectations. Unusual put buying during refinery maintenance seasons or inventory build reports can signal margin compression ahead.
