The Greeks measure how an option's value reacts: delta to the underlying price, gamma to delta itself, vega to volatility, theta to the passage of time. Traders hedge by neutralizing them. Educational tool, not financial advice.

Gamma0.0221

Vega (per 1% vol)0.276

Theta (per day)-0.024

Governing equation

Δ = N (d_{1}), d_{1} = \frac{ln ( 100/100 ) + ( 0.04 + 0.2 5 ^{2} /2 ) 0.5}{0.25 0.5} = 0.202 \Rightarrow Δ = 0.580

Reading this result: Near the money, gamma and vega peak: the option is most sensitive to both price swings and changes in volatility (vega 0.28 per 1% vol).
