GEX
Gamma Exposure — net gamma of all options at each strike. Tells you if dealers amplify or suppress moves.
GUPS
Gamma Unwind Probability Score. Measures risk of a gamma-driven cascade. 0–100 scale, >60 is elevated.
GAPS
GEX-Adjusted Projected Spread. Expected move recalculated using dealer gamma positioning.
Call Wall
Strike with highest positive gamma. Acts as resistance in positive GEX; less reliable in negative GEX.
Put Wall
Strike with highest negative gamma. Acts as support in positive GEX regimes.
Flip Point
Price where net GEX flips from positive to negative. Critical regime change level.
IV Rank
Current IV relative to its 52-week range. 0 = lowest, 100 = highest. Key for premium selling timing.
0DTE
Zero Days to Expiration. Options expiring today. Extreme gamma, extreme theta. The fastest game in town.
