Understanding Numerical Methods in Quantitative Finance: Binomial Trees and Finite Difference Methods
A formula-first, computation-heavy course for quant analyst aspirants, prop trading applicants, and systematizing traders on the two workhorse numerical methods for option pricing: binomial trees and finite difference schemes. Builds from why closed-form Black-Scholes breaks down, through single and multi-step trees, American option early exercise, and on to explicit, implicit, and Crank-Nicolson finite difference methods. Grounded throughout in Nifty 50, Bank Nifty, and NSE stock examples.
