Start here — a live market snapshot and how an option desk's view of risk fits together
Greeks explorer — one option seen seven ways: against spot, through time, against volatility, as a surface, compared with other strikes and maturities, and through its P&L
Strategies — 37 structures with payoff, breakevens, leg-by-leg Greeks, and a comparison of any two
Exotics — digitals, barriers, Asians and lookbacks against their vanilla benchmark, with a Monte Carlo check
My book — build a portfolio, read its risk ladders, scenario heatmap and stress tests, and hedge it
Trading simulator — run the book day by day where realised volatility differs from implied, and see the P&L split by Greek
Interview drills — self-marked questions, mental-maths shortcuts, flashcards and a question bank
