Syllabus
work through in order; each lesson ends with a short check- ✓ The expected moveHow option prices translate into a range the market is pricing in for a stock over a given period. 2 min
- ✓ Probabilities from option pricesHow Options Band turns option prices into model-estimated odds that a stock finishes above or below a level. 3 min
- ✓ Open interestWhat open interest counts, how it differs from volume, and why it only updates once a day. 2 min
- ✓ Options volumeWhat options volume measures, what it cannot tell you on its own, and how it pairs with open interest. 3 min
- ✓ The put/call ratioA single number comparing put and call activity — a gauge of lopsided flow, not of what traders intend. 2 min
- ✓ Earnings and volatility crushWhy implied volatility builds before an earnings report, collapses after it, and how Options Band measures the reaction. 3 min
