3. Feasibility & Mean-Reversion Telemetry

Contextual stop-loss monitoring: required move to breakeven vs. remaining DTE expected volatility

Breakeven Line$40.87Short strike minus credit
Move Needed to Win+1.52%+$0.61 to BE
Expected Move (1σ)±3.78%Volatility over remaining DTE
Feasibility Ratio0.40x EMThreshold: ≤ 1.25x EM
Long Wing Barrier$39.50Structural floor intact
Feasibility Rule Status: Feasible (Recovery Projected). The required move to breakeven (1.52%) represents only 40% of the statistical expected move over the remaining holding window, meaning mean reversion remains highly feasible.
