The RFD-TV Finance app is a custom XPression application developed for RFD-TV to generate and display commodity charts and quote tables live in broadcasts. It uses data from barchart.com.

It is split into 2 components: 1 client app and 1 XPression server app. The server app runs on the XPression machine while the client app can be installed elsewhere on the network. The client app is responsible for all communication with the barchart web service.

Finance Client App

The client application can be installed on any machine that will be able to access the XPression machine via a network address. It is responsible for all communication with the barchart internet data service.

Prerequisites

Windows 8, 10, or Windows Server 2012 or greater is recommended.

Microsoft .NET Framework 6.1 or greater which can be downloaded from a Microsoft website to suit your version of Windows. This must be the FULL version and not the Client Profile version.

Initial Configuration

The first time you install the application you will need to customize a few settings and preferences.

XPression Server Connection

The client’s remote config settings must match what is set on the XPression server application to enable a successful connection. The server provides support for using either TCP or HTTP protocols. The TCP protocol is recommended.

NOTE: the client app can be run without connecting to the XPression server. Press the Don’t connect button to launch the client app in standalone mode. This allows you to test data access and other client features.

Barchart API Key

To access the data the application requires the use of an api key that will be provided to you by barchart when you subscribe to the service.

The key is set via the File menu - Preferences option. It is the first value displayed at the top of the Preferences window.

No XPression Mode

You can run the client application without connecting to the XPression server. Press the Don’t connect button to launch the client app in standalone mode. You will be able to:

  • search for commodities available to you for chart generation

  • generate and preview charts with data from barchart

  • generate and preview commodity quote table data from barchart

  • build playlists of charts and tables to be used in a later session.

  • update preferences

Preferences

You can change many of the features of the generated charts with the Preferences window. It is accessed via File menu - Preferences...

NOTE: the changes apply only to charts that are generated after the changes are saved and do not apply to existing charts. The exception to this is the chart preview background which is used in local preview only and is not part of what is displayed in XPression.

Barchart API Key

Without a valid API key you won’t be able to access any data to generate charts or commodity tables.

Chart Size

The chart size here controls the size of the generated chart image. It should match the size of the object in the XPression scene that is used to display the chart.

Search - Exchanges

This list of exchange codes is used to filter the search results. Note that you can only use exchanges that are included in your barchart API license.

The default value of this preference is: CBOT, CBOTM, CME, MGEX, KCBT, WCE

Auto-Update

This intraday values displayed on a generated chart scene can be automatically updated just before the graphic is sent to air. This only affects the intraday current value and change. It does not regenerate the chart image.
