The Greeks
- Delta (call)
- 0.6198
- Put: -0.3802
- Delta tells you how much the option's price moves for every $1 change in the stock. A call with Δ = 0.50 gains about $0.50 if the stock rises $1. Call deltas go from 0 (unlikely to finish in the money) to 1 (deep in the money); put deltas are negative and go from 0 to −1.
- Gamma
- 0.0152
- Shared call/put
- Gamma is the "acceleration" of Delta — how fast Delta changes as the stock moves. High Gamma near expiry means small moves in the stock can flip the option quickly between in-the-money and out-of-the-money.
- Theta / day (call)
- -0.0192
- Put: -0.0074
- Theta is how much value the option loses each day just from the clock ticking down, holding everything else constant. A Theta of −0.05 means the option loses about 5¢ per day. It's the "rent" of owning an option.
- Vega / 1%
- 0.3808
- Per 1% σ move
- Vega is how sensitive the option is to changes in implied volatility — the market's expectation of how much the stock will move. A Vega of 0.20 means the option gains about 20¢ if expected volatility rises by 1 percentage point.
σ — Volatility override
Range 0.5 to 300, step 0.5. This value drives the BS model price and Greeks.
