Unit 1 · Level 5 · Volatility Mastery
Gamma & vega: the fast greeks
Delta and theta you know. GAMMA: how fast delta itself changes. It runs highest near the strike close to expiry, where options behave explosively. VEGA: sensitivity to implied volatility. Long options gain when IV rises and bleed when it crushes. Four dials, full instrument panel.
Free to play. No ads, no token, no account needed to start.
What you get asked
Why do 0-days-to-expiry (0DTE) options move so violently?
Gamma is the accelerator pedal. 0DTE is maximum acceleration with maximum theta, a knife fight in a phone booth. Know WHY before ever touching them.
Match the greek to its question
Every options P&L surprise you'll ever have is one of these four dials you weren't watching.
Market-maker ___ hedging (their forced buying and selling as deltas shift) can amplify index moves near big strikes.
'Gamma squeezes' and pinning at round strikes: dealer flows are the stock market's liquidation cascades. Same physics you learned in perps. Forced flows move prices.
You're long a call and IV drops 10 points while price stays flat. Vega says…
Every option position is a volatility position. Masters CHOOSE their vega exposure; tourists discover it on settlement.
The greeks, mastered, turn options trading into…
Instead of one mystery ticket. Boss next, then the market's engine room: microstructure. 🐜
