This package aims to provide a pure Julia version of the popular open source library QuantLib (written in C++ and interfaced with other languages via SWIG). Right now the package is in an alpha state, but there is quite a bit of functionality already.
using Pkg; Pkg.add("QuantLib")Note: only supports versions of Julia 1.0 and up
The package essentially contains the main QuantLib module and two sub-modules for various time-based and math-based operations. Below is a fairly up-to-date status of what is included.
