    Move the price control to compare the same structures at expiry. Values before expiry also depend on time value and volatility; an estimated before-expiry value is calculated in the paid hedge workspace.

    Save the hedge with its costs, coverage, and dates.

    Keep the selected contracts and quote snapshot attached to your position. Record the decision, follow the protection period, and reopen the comparison when your coverage or underlying case changes.

    Expiry P&L from today: q(S_T−S_0) + n·m·max(K−S_T,0) − n·m·p − fees for a protective put; a collar adds −n·m·max(S_T−K_c,0) and nets the written call's bid against the put's ask. Purchased options use the ask, written options the bid; fees are an assumed $0.65 per contract. Only standard 100-share contracts are used.
