QuantLibXL (Excel QuantLibAddin) provides a [limited subset of] QuantLib functionality directly in Excel. However, its development follows the development of QuantLib with a lag, e.g. currently the last modified date in project repository is 2017-05-02. I tried to build QuantLibXL with currently latest version of the Visual Studio (success) and to bind it to the latest version of QuantLib (no way).

We have already used QuantLib at letYourMoneyGrow.com several times, in particular to provide a helpful scenario simulator for option traders. QuantLib User Meeting 2017, in which I also took part, provides insights on how to make QuantLib even more accessible for the "mere mortals".

Remarkably, many market players in energy market still cannot calculate the fair value of a gas storage. In particular, many of them rely on perfect foresight. We put online a simple but correct model from QuantLib. Confidence intervals are estimated as well.
NB! This time not for retail investors but for the colleagues from energy industry. Have a look at short introductory video.
Gas Storage is a relatively complex option to evaluate, esp. if there are non-trivial constraints. Remarkably, many energy companies cannot correctly evaluate even the simplest storage contracts. Moreover, they often resort to a so-called perfect foresight: the price paths are considered random but once the price path is known, it is assumed to be known completely (like at the left-hand sketch).

Some of QuantLib functionality is ported to R in RQuantLib. In particular the pricing of Barrier options. Unfortunately, only European. But we need American in order to price and simulate future scenarios for the so-called KO-Zertifikate (Knock-Out Warrants), which are quite popular among German retail traders. We show how to quickly adopt the code from QuantLib testsuite, compile it under Linux and integrate with R and web.

Many retail investors are unaware that the option price sometimes depends on the (implied) volatility much stronger than on the price of underlying. They also often underestimate the losses of time value. Our option calculator lets you estimate the future fair price of an option by different pairs of implied volatility and underlying price.
