SIMULATOR Spread: Germany (-1.5)

A live, interactive instrument for dissecting a single binary position. Sweep the inputs and watch every indicator recompute — payoff geometry, Kelly growth, Bayesian posterior, KL divergence, cost waterfall, Monte-Carlo equity fan, forecast calibration. Companion to the live /feed/pm-fifwc-ger-civ-2026-06-20-spread-home-1pt5 page.
