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.
