  FTX.us uses a different API domain for both REST and Websockets. Headers are also slightly different.

  Set the domain in all client options to 'ftxus' to connect to ftx.us. Examples for REST and Websockets are below.

  Note: some API calls may be unavailable due to limitations in the FTX.us APIs.
