About

An option looks simple on a screenshot: a strike, a date, a price that doubled. The rules behind it are not on the screenshot, and most people learn them by losing the premium. This course teaches them first.

It’s a game. Each chapter is a short beat from a group chat, a few cards that explain one idea with real numbers, and a handful of puzzles where you put it to work: price the contract, split the premium, read the chain at 3pm on a Friday. Retries are unlimited, and every wrong answer tells you why. RocketCo is fictional, and nothing here is a trade or advice.

It’s made by the same person as balancesheet.art, which teaches the accounting behind the stock. If something is confusing or you have an idea, the Feedback link at the bottom of every page comes straight to me. I read all of it.
