Course · 10 lessons
Options, from the first contract to the iron condor.
The first five lessons explain how an option works and what sets its price. The last five cover the main strategies and their risks. Each lesson takes a few minutes.
How the course works
Every lesson uses the same example stock. It costs $100, its volatility is 25% a year, the interest rate is 4% and it pays no dividend. The options have 90 days to expiration.
A model script calculates every price, payoff and chance of profit with the Black-Scholes model. So the numbers agree from one lesson to the next, and you can check each one. Real quotes differ from these model prices.
The lessons
- An option is a right with a deadline. Calls, puts, strikes and the 100-share contract.
- Four positions build every strategy. Long and short calls and puts, at expiration.
- An option price is intrinsic value plus time value. Intrinsic value, time value, five inputs and put-call parity.
- The Greeks tell you how an option price will move. Delta, gamma, theta, vega and rho for one contract.
- Time decay speeds up as expiration gets near. Theta near expiration, implied volatility and the expected move.
- A covered call and a cash-secured put are almost the same trade. Two income trades, and why they have the same shape.
- Protection costs money, or it costs upside. A floor under your shares, and two ways to pay for it.
- A spread caps the gain to cut the cost. Debit and credit spreads, and the two rules that size them.
- Straddles and iron condors are bets on how far the stock moves. Trades on the size of a move, not its direction.
- Know the exit rules before you trade an option. Exercise, assignment, leverage and the costs the model leaves out.

For a trade with stock, the cost or credit is for the options only. The 100 shares cost $10,000 more, and a cash-secured put holds $9,500 in cash.
The chance of profit is for the model stock. It does not tell you which trade is better. A trade that wins often usually wins small amounts, as lesson 2 shows.
