Response
gamma_flipnumberPrice level where aggregate dealer gamma changes sign. Computed via Brentq root-finding on the continuous GEX curve. The single most important level for regime determination.
gamma_flip_confidencenumberConfidence score (0.0 to 1.0) for the gamma flip level. Higher values indicate a sharper, more reliable zero-crossing.
put_wallnumberStrike with the highest concentration of put gamma. Acts as a strong support level because dealer hedging of puts creates buying pressure as price approaches.
call_wallnumberStrike with the highest concentration of call gamma. Acts as a resistance level because dealer hedging of calls creates selling pressure as price approaches.
max_painnumberPrice level where the total value of all outstanding options is minimized. Prices tend to gravitate toward max pain near expiration.
max_gammanumberStrike with the single largest absolute gamma exposure. This is the strongest mechanical magnet or repeller.
gamma_gravitynumberWeighted average of strike prices by gamma magnitude. Price tends to drift toward gamma gravity in positive gamma environments.
gravity_pullnumberStrength of the gravitational pull toward gamma_gravity. Higher values indicate stronger mean-reversion toward that level.
Note
These levels update continuously as options are traded and open interest changes. In high-volume environments (e.g., OPEX weeks), levels can shift significantly intraday. The gamma flip is the most stable level; put and call walls can move with large block trades.
