This part two dealing with transforming a system of differential equations into a system of algebraic equations. In part one, we had the advantage of dealing with linear equations and solving the problem amounted to finding the inverse of a sparse matrix. In this video we will look at the nonlinear case and adapt our techniques to create a system of equations we can solve using Scipy's fsolve function.

I had a deep in-the-money short call on an ETF that was going ex-dividend. Risk of assignment depends on the value of the dividend compared to the extrinsic value left in the option. How do we determine the dividend value of an ETF which does not announce the amount beforehand? Donate: http://paypal.me/kpmooney ... https://www.youtube.com/watch?v=vKX371HcbXc

I look at using Newton’s method to solve for the implied volatility of an option. This is done using the Black-Scholes model and a simple Python script. My mouth and brain were apparently totally out of sync when discussing the numbers in the slide showing the spreadsheet results for the roots of a parabola. This is one of those situations where you should pay attention to what I am thinking rather than what I am saying. In any case, the numbers in the spreadsheet are correct.
