3. Feasibility & Mean-Reversion Telemetry

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

Breakeven Line$99.29Short strike minus credit
Move Needed to Win+0.34%+$0.34 to BE
Expected Move (1σ)±7.32%Volatility over remaining DTE
Feasibility Ratio0.05x EMThreshold: ≤ 1.25x EM
Long Wing Barrier$98.00Structural floor intact
Feasibility Rule Status: Feasible (Recovery Projected). The required move to breakeven (0.34%) represents only 5% of the statistical expected move over the remaining holding window, meaning mean reversion remains highly feasible.

This successfully eliminated tail risk and preserved $2,450.00 that was otherwise exposed under the full spread width.
