Warning: Barone-Adesi-Whaley critical commodity price calculation is used.

It has not been modified to see whether the method of Ju is faster.

Ju does not say how he solves the equation for the critical stock price, e.g. Newton method.

He just gives the solution.

The method of BAW gives answers to the same accuracy as in Ju (1999).
