The currency that Stockade uses is pulled directly from the language settings on your computer. If your operating system is setup to use the American format rather than English, then Stockade will use $ instead of £. In order to change the language settings of your computer, navigate to Start > Control Panel > Clock, Language, and Region > Regional and Language > Keyboards and Languages, select English (United Kingdom) option below Display language and click OK.
