Threshold-Cusp Gamma Harvest Near Strike Boundaries

Find threshold ('above X?') markets where the real-world number is sitting right at the resolution line late in the market's life, then trade the now-extreme price sensitivity as the number wobbles back and forth across the line, scalping each repricing. Digital gamma just means how violently the yes/no price swings per small move when you're near the boundary; that convexity gets sharper as resolution nears.

Will the next monthly CPI print round to exactly 3.0%?
Will a given NFL team finish the next season above .500?
