The dashed line: value before expiry, with time value left.Legs & Greeks
| Leg | Strike | Expiry | Premium | Delta | Gamma | Theta/day | Vega |
|---|---|---|---|---|---|---|---|
| Buy 1 Call | $345 | 30d | $13.19 | 55.2 | 1.33 | −$21.60 | $39.29 |
| Whole position | $1,319 | 55.2 | 1.33 | −$21.60 | $39.29 | ||
Premium is per share; Greeks are for the whole leg in dollars or shares. Delta: shares of stock the position acts like. Theta: what a day of time does to it. Vega: what one point more volatility does.
Premiums are theoretical (Black-Scholes with the volatility and rate above, no dividends, European exercise), not live option quotes, which free data doesn't include. Real prices differ, especially around earnings and for far-from-the-money strikes. For learning, not advice.
