Move one input. Watch the effect. Start with the five Greeks that describe how an option responds to change.
01 / PRICE SENSITIVITY
Delta estimates the change in an option’s price for a $1 rise in the underlying, with other inputs held steady. Calls generally have positive delta; puts generally have negative delta.
Try moving the stock price. Notice that the option’s price does not move dollar for dollar.
30 days to expiry · 30% volatility · 4% rate · No dividends
A hypothetical European-style option using the Black–Scholes model, a $100 strike and no dividends. Prices are per share. Theta is per calendar day; vega and rho are per one percentage point. We vary one input at a time. These are theoretical estimates, not market quotes, profit forecasts or trade recommendations. The model does not account for early exercise, fees, spreads or changing market conditions.

One idea at a time
Read an explanation, try the question yourself, then reveal the worked answer. Understanding grows when you examine why an answer fits.

Connect risk, research and human review before considering a real decision.
Agents and human oversight
A confident explanation is a starting point for review. Learn to check sources, recognize limits and separate a proposed action from permission to act.

Options, in plain English
A call gives its holder the right to buy the underlying at the strike price. A put gives its holder the right to sell. Each contract has an expiry and an exercise style. The holder pays a premium; the seller takes on an obligation if assigned. Contract specifications determine the deliverable and multiplier.
Start with the underlying, strike, expiry, exercise style and contract multiplier. Understand the premium, bid–ask spread and liquidity. Examine scenarios where the price moves against you, time passes or volatility changes. Know how exercise and assignment work, and what your broker requires.
A buyer can lose the entire premium paid. Some short-option positions can lose more than the credit received, and an uncovered short call can have unlimited loss. Exercise or assignment can create stock positions and additional obligations. A calculator is a model, not a guarantee.
