Choose a concept path and start exploring.
Each path combines a visual model, plain-language intuition, equations and thought questions.
Foundations
Mathematics for Quantitative Finance
Start from first principles and build intuition through 84 interactive lessons, from algebra and calculus to probability, estimation, numerical methods and stochastic pricing. Includes a glossary, worked examples and chapter projects.
See the idea. Build the mathematics →Risk sensitivities
DV01, CS01, delta, gamma, vega and curvature across bonds, swaps, CDS, equities and options.
Explore price and risk →Stochastic calculus
Probability, Brownian motion, martingales, Itô calculus, geometric Brownian motion and Black–Scholes.
Open the stochastic path →Yield Curve & Bootstrapping Lab
Build discount curves, infer forwards, compare interpolation and reprice bonds and swaps across seven interactive concepts.
Build the curve →Explore professional applications
Treasury Risk Lab
Build a bank balance sheet, understand funding and FTP, explore liquidity, rates, FX and collateral, then defend an ALCO decision in 33 interactive lessons with 330 thought questions.
From cash basics to treasury decisions →SIMM · Initial Margin Lab
Follow sensitivities through six risk classes, concentration, delta, vega and curvature. Explore hedges, CRIF, collateral and governance with interactive calculations and thought questions.
Understand the margin →Credit Risk & Loss Lab
Explore seven portfolio types, PD, LGD, EAD, default dependence, variable selection, model validation, IFRS 9 ECL and SICR in 34 interactive concepts.
Follow the borrower to the loss →FRTB market risk
SBM delta, vega and curvature for all seven risk classes, DRC, RRAO, IMA ES, NMRFs, RFET, PLAT and backtesting, plus trade-to-capital mapping, visual data tests and a capital optimisation sandbox.
Open the FRTB path →SA-CVA counterparty risk
CVA valuation, netting, collateral, wrong-way risk, hedging and six PRA risk-class laboratories, with delta and vega aggregation.
Open the SA-CVA path →SA-CCR counterparty exposure
Replacement cost, netting, collateral, potential future exposure, six asset-class add-ons and UK alpha treatment.
Open the SA-CCR path →XVA · Valuation adjustments
Explore credit, own credit, funding, collateral, initial margin and capital, then connect wrong-way risk, portfolio pricing, clearing, reserves and tax in 13 interactive lessons.
Understand the whole trade →IRRBB Lab · Banking book
Build a balance sheet, trace cash flows and apply six supervisory shocks. Explore ΔEVE, ΔNII, deposits, prepayments, basis risk, optionality and hedging in 19 applets with 190 thought questions.
Build and stress a bank →FRTB Regulation Divergences
Search FRTB topics and identify differences between PRA, the March 2026 US proposal and Basel with source references and calculation implications.
Analyse the divergences →Liquidity & Funding Risk Lab
Explore LCR, NSFR, cash survival, funding concentration, collateral and funding actions across seven interactive concepts.
Follow the cash →How to use the applets
Begin with the default scenario, change one input at a time, and explain the result in your own words. The “build the intuition” questions are deliberately inquisitive rather than calculation-heavy.
