Paul Wilmott Introduces Quantitative Finance

A fourteen-deck interactive companion to Paul Wilmott's textbook — from the binomial model and Black–Scholes through exotic options, interest rate models, and Monte Carlo. Every key idea of the book turned into a draggable, scrubbable, animated picture in the browser.

Pedagogical arc

01 – 02  Markets & Derivatives

The instruments themselves — equities, FX, commodities, forwards, futures, options — and the no-arbitrage logic that makes them all related.

03 – 05  The Random Walk

From the discrete binomial tree to continuous Brownian motion and the basic stochastic calculus needed to price an option.

06 – 08  The Black–Scholes World

The PDE, the closed-form formulæ, the Greeks, the implied-volatility surface, and the hedging strategies that follow.

09 – 10  Exotic & Multi-asset

Barriers, Asians, lookbacks, compounds — and what happens when you write options on baskets, spreads or exchanges of two assets.

11 – 12  Fixed Income

Yield, duration, convexity, swaps, the yield curve — then short-rate models (Vasicek, CIR, HW) and the HJM / BGM forward-rate framework.

13 – 14  Risk & Numerics

Portfolio theory, CAPM, VaR, credit risk and CrashMetrics — then the finite-difference and Monte Carlo machinery that prices everything else.

Why this companion? Wilmott's book is famously written like a working quant talks — informal, fast-moving, packed with the actual reasoning a desk uses to build a model and hedge a book. That style is great to learn from but punishing to flip back to: the key picture you need next is sometimes scattered across three sub-chapters and an exercise. This series instead pins each of those pictures to a slide and makes the parameters draggable. Where the book says "now imagine the volatility is a smile of the form…" you'll have a slider and the smile.

Read the book and the deck side by side — chapter and section numbers in each deck correspond directly to Wilmott's second edition.
