IV crush is the overnight collapse of option implied volatility after an event. We scanned six weeks of the US options tape and measured every big one.
Pin one real Tesla call through its Q1 earnings 8-K and watch implied volatility, price and delta move as the result lands and the IV crush follows.
Delta, gamma, theta, vega and rho, the five option greeks, demonstrated by tracing one real SPY call through its whole life against the stock.
Vega measures an option's sensitivity to implied volatility. Watch IV spike on a real SPY call, see vega grow with time, and drive the earnings vol crush.
Implied volatility is the future move an option's price implies. See IV across stocks, the term structure, the volatility skew, and a year of SPY's vol regime.
Theta measures an option's daily time decay. Watch it deepen on a real SPY call into expiry, see decay accelerate, and why it's the seller's income.
Gamma measures how fast an option's delta changes. See the at-the-money bell, why it spikes near expiry, and how it powers 0DTE and the gamma squeeze.
Option delta measures how much an option moves per $1 in the stock. Watch it track a real SPY call across the strike and see the moneyness S-curve.
