Writing enums
~~~~~~~~~~~~~
Elements cannot be added to enums in a new version of the code. Hence, enums are only a good fit for genuinely static
data that will never change (e.g. days of the week). A ``Buy`` or ``Sell`` flag is another. However, something like
``Trade Type`` or ``Currency Code`` will likely change. For those, it is preferable to choose another representation,
such as a string.
