Stable: ATM call + put

Sell one call and one put at the same nearest available common strike K. Buy a call above K and a put below K, with the same expiry. The result includes all four options together.

Target protective strikes: K × (1 + 0.5%) and K × (1 − 0.5%). The closest available outward strikes are used; the grid can make the actual wings unequal.

In the option columns, Call and Put identify the contract type. The strike is shown first; the prices below are entry → exit, per share. The single P&L is for the complete four-option set after commissions.

Historical bid/ask model

Contracts and strikes are selected from the chain available that day. At 09:35 New York, short legs sell at bid and long legs buy at ask using the latest quote within the current regular session. A quote remains current until updated. Positions close at the opposite bid/ask 15 minutes before the stock session ends on expiry day, including shortened sessions.

The model reserves $0.65 per leg for entry and again for exit. This conservative fee estimate includes long options valued at zero with exercise waived; their price is marked with an asterisk.

Displayed prices are historical quotes, not confirmed simultaneous fills. Commissions apply on entry and exit. Early assignment, stock delivery, intraday stops, and financing are not simulated. Risk at expiry is theoretical; quoted closing costs can exceed the spread width.

For 19 closed trades, exit quote size cannot support the budget-sized position. The scaled total is incomplete; these trades remain in the one-contract results.
