After specifying the currency units you wish to use, you must specify how the growth of the investment is to be computed. This can be any function, but will often be the output of a History Generator element.

You can use an Investment element to model a collection of investments (by entering vectors of inputs), and you can specify a correlation matrix for the investments (using several different correlation schemes).
Purchases and sales of the investment can be entered as continuous rates or discrete items.
The primary output is the current value of the investment:
