@Charles Hello, the Exchange extension is self-contained. You do not need to purchase access to any other extensions for a fully functional exchange. The other components you need are the parent plugin which is freely available from wordpress.org, and any coin adapters you need, all available for free from this site when you sign up.
To show the buy/sell boxes, use the shortcodes [wallets_exchange_limit_buy] and [wallets_exchange_limit_sell]. For a full list of shortcodes that you can use and their attributes, please refer to the documentation for the exchange. The documentation is the PDF file included in the bundle download of the exchange.
You also have the option of using the same UIs as widgets, it’s up to you which method you prefer.
@dynamitemedia Thanks, I believe the OP is showing screenshots from other exchanges to explain the buy/sell boxes.
with regards
