Stock replacement (1-2yr) (Bucket A) — 33 contracts/chain

Every chain's best Fortress sized to the SAME contract count for apples-to-apples capital / max-loss / margin comparison. Change the dropdown to resize. Tick up to 2 chains in the ☑ column to compare them side by side. Structure: + = bought (long), = sold (short). Click any BE & CC-Safe cell to open that chain's CC-Safe Strike card.

★ Score = (Weighted P&L ÷ Max Loss) × horizon-fit. Weighted P&L = expected expiry dollars across a weighted scenario basket. Moderate-bull basket (Bucket A weights): +25% carries the biggest weight, then +50% / +75%; flat and -20% count (they penalize high breakevens); +100% / +200% taper off — rewards stock-replacement structures that pay across the likely-bull range. ÷ Max Loss turns it into return-per-dollar-at-risk (capital efficiency, so a deeper/longer structure is not rewarded just for costing more). × horizon-fit peaks in the 1-2yr window (365-730 DTE) and tapers outside it, keeping the pick inside the thesis horizon. All three terms are size-invariant, so the ★ does not move when you change the contract count.

Margin = real IBKR portfolio (TIMS) maintenance margin from a whatIf order on the 3-leg open combo (BUY LC / SELL SP / BUY HP), the same engine TWS shows. This is the ongoing capital held; the one-time initial requirement to open is higher. Stored at the analyzed contract count and rescaled linearly by the dropdown (TIMS has mild concentration non-linearity, so verify the exact figure in TWS before sizing). For net-long Bucket A synthetics this runs well above the old Reg-T put-spread width, which ignored the long call's directional risk.

★ Score = (Weighted P&L ÷ Max Loss) × horizon-fit. Weighted P&L = expected expiry dollars across a weighted scenario basket. Convexity basket (Bucket B weights): +75% and +100% carry the biggest weight, +200% tail counted, downside (-20% / flat) lightly weighted — rewards OTM structures that pay big on a strong move. ÷ Max Loss turns it into return-per-dollar-at-risk (capital efficiency, so a deeper/longer structure is not rewarded just for costing more). × horizon-fit peaks in the 1-2yr window (365-730 DTE) and tapers outside it, keeping the pick inside the thesis horizon.
