Detailed Description

Pricing engine for double barrier european options using analytical formulae.

The formulas are taken from "The complete guide to option pricing formulas 2nd Ed", E.G. Haug, McGraw-Hill, p.156 and following. Implements the Ikeda and Kunitomo series (see "Pricing Options with Curved Boundaries" Mathematical Finance 2/1992"). This code handles only flat barriers

Note

the formula holds only when strike is in the barrier range

Tests:

the correctness of the returned value is tested by reproducing results available in literature.
