For teachers and investment clubs
Updated 15 October 2026.
Free for a class
The lessons of stage 1, the first practice flight, the earnings check, the Research Lab and the question pages are free, with no sign-up and nothing collected from students: progress stays in each student's own browser. Every number comes from a stated formula (Black–Scholes) on simulated markets, labelled as such. Nothing on the site recommends a trade.
A ten-minute session
- Predict (2 minutes). Ask: a stock rises $2 the morning after its report; does a call bought the night before gain? Take a show of hands.
- Try it (3 minutes). Open this page and press "The morning after earnings": the call goes from $3.51 to $3.02. Each bar is one force: the stock's rise, time, and the fall in implied volatility.
- See it (3 minutes). In the lesson on the crush, the 3D card shows the whole surface sinking while the call rides on it.
- Test a claim (2 minutes). In the Lab, a streak, or skill? runs 100,000 simulated traders, most of them coin flips: many win long streaks by luck alone.
For a club that meets weekly
A new practice case every Monday (the weekly clinic) gives a club one decision to argue about: a loss limit, a trade or none, and every outcome over thousands of simulated paths afterwards. The full course and the clinic are part of the paid subscription; write to us about access for a class.
