Your question is Greeks and Time Decay. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do the Greeks (Delta, Gamma, Theta, Vega) impact an option’s price as it approaches expiration?
Explain the directional effect of each Greek, how the behavior changes near expiration, and how the Greeks interact when spot, volatility, and time move simultaneously. Use the illustrative inputs provided in the answer framework to quantify a one-day premium change, and identify the principal risk for a market maker holding the option.
