| It's very hard to read your expression, but it looks like it has the form A x + B x^(-1/2), where (A,B) are independent of x. If so, you want to solve 2 A - B x^(-3/2) = 0 and the answer is x = (2 A/B)^(-2/3). If I'm wrong about the form,... |
| If I use FinancialDerivative for the American-style put option with no method chosen, but a diagonal choice "GridSize"->{npts,npts}, the method apparently converges as npts increases. My questions: Q1. With this diagonal choice, can I rely on the... |
| Thanks -- any thoughts on the issue with Mathematica online? p.s. I have put the issue to Wolfram Technical Support also |
| Thank you both very much. Since my original post, I discovered the exchange has a somewhat newer api and suggests a query no often than once every 2 secs. Also I just wanted a last price that I could feed to other modules. So, the code below is what... |
